- VIRUSES (1.0)
- ==============
-
- HELP! I HAVE A VIRUS. (1.1)
- -----------------------------
-
- 90% of all problems reportedly caused by viruses are actually
- due to mundane bugs in software (and 90% of all statistics are made
- up :-) ). Check your system with the latest version of Disinfectant,
- 3.3 as of this writing, by the excellent John Norstad from
- Northwestern University. Disinfectant is absolutely free and is
- available from sumex-aim and all the other usual suspects. It's easy
- to use and can completely protect your system from currently known
- Macintosh viruses. Releases to protect from new viruses are normally
- made within a day or two of the first confirmed sighting and capture
- of a new virus, and make their merry way around the electronic
- highways faster than any Macintosh virus ever has.
-
-
- I THINK I'VE FOUND A NEW VIRUS. WHAT DO I DO? (1.2)
- -----------------------------------------------------
-
- DON'T post a report to any comp.sys.mac.* newsgroup. 99% of
- all suspected new viruses are merely mundane bugs in the system or
- applications being used; and even if you really have found a new
- virus, there's nothing we can do about it anyway. You'll only
- generate a lot of panicked, follow-up reports from people who'll
- blame every crash of QuarkXPress on the new virus.
-
- If your system is protected against known viruses by
- Disinfectant or one of the other anti-virus packages and you suspect
- a new virus is causing you trouble, first consult with the most
- knowledgeable local guru about your problem. Nine times out of ten,
- he or she will identify it as a boring, ordinary, known bug in the
- software. If you are the local guru and still think you may have
- found a new virus, and have thoroughly checked out all other
- possibilities, then, and only then, send a detailed description of
- your problem to j-norstad@nwu.edu. Check the Disinfectant manual
- for procedures to follow before reporting a new virus.
-
- Please remember that it is VERY unlikely you have actually
- found a new virus. Around the world in all of 1992 only four
- new Macintosh viruses were discovered. Of all the suspected
- Macintosh viruses which were reported to Usenet before being
- isolated by a recognized virus expert, exactly none were eventually
- confirmed. One recent public virus report, the so-called M virus,
- turned out to be the result of a boring, ordinary bug in a common
- extension. The report which received the most attention, the
- so-called Aliens virus, remains unconfirmed and was probably
- the result of corrupt system software.

- ==============================
- PRINTING AND POSTSCRIPT (2.0)
- ==============================
-
- HOW DO I MAKE A POSTSCRIPT FILE? (2.1)
- ---------------------------------------
-
- First make sure a LaserWriter driver is in your System Folder.
- It doesn't really matter which one although LaserWriter driver 8.1.1
- is the best. This driver is avilable from ftp.apple.com in the
- directory /dts/mac/sys.soft/imaging/laserwriter.8.1 and works
- with System 6.0.5 and later. If you're using the System 6 driver,
- you'll need a Laser Prep file in your System Folder as well as
- the LaserWriter driver and will also need to turn off background
- printing. Once you've verified that there is indeed a LaserWriter
- driver in the System Folder, select LaserWriter in the Chooser.
- A dialog box will probably pop up informing you that the LaserWriter
- requires Appletalk and asking if you want to turn Appletalk
- on. Whether you have AppleTalk or not click OK. Then select
- Page Setup... from the File menu to format your document
- for the LaserWriter. Next select Print... from the File menu.
-
- If you're using LaserWriter driver 7.0 or later, the Print
- dialog box that appears will have a radio button for Destination
- near the bottom. Click PostScript File. The Print button at the
- top should change to a Save button. Click it and you'll get a
- standard file dialog asking you what to name and where to save
- the PostScript file.
-
- If you're using LaserWriter driver 6.0.x or 5.2, the procedure
- is more complicated. When the Print dialog box pops up, position
- the cursor over the Print button and hold the mouse button down and
- keep it down like you're going to click and drag. Then, with your
- other hand, press and hold the K key. If you'll eventually print
- the file on a non- Apple PostScript printer, especially one not
- designed with the Macintosh in mind, also hold down the Command
- key. Using Command-K instead of plain K includes some Mac specific
- information non-Apple-oriented PostScript printers need to know
- about. Now let the mouse button up. When you see a message box
- that says "Creating PostScript file," take your finger off the
- K key.
-
- After you've gotten the message "Creating PostScript file" you
- should find a file called PostScript0 in the same folder as the
- application you were printing from. This is the file you just
- printed. Rename it before you forget what it is. If you print to
- disk (what this whole process is officially called) more than once,
- the second file will be called PostScript1, the third PostScript2,
- and so on. It really is much easier to use the System 7
- LaserWriter driver.
-
-
- HOW DO I PRINT A POSTSCRIPT FILE? (2.2)
- ----------------------------------------
-
- On a Macintosh you'll need the LaserWriter Font Utility
- available on the high density TidBits disk from System 7 or the
- More TidBits disk from the 800K distribution. A more feature-rich
- version called simply LaserWriter Utility is available for
- anonymous ftp from ftp.apple.com in /dts/mac/sys.soft/imaging.
- Both utilities allows you to send files to the LaserWriter in such
- a way that PostScript commands get interpreted as PostScript rather
- than as text to be printed. If you're printing to a PostScript
- printer connected to something other than a Macintosh, you'll need
- to consult your local system gurus. A simple "lpr filename.ps"
- works on my Sparc, but your mileage may vary.
-
-
- WHY WON'T MY POSTSCRIPT FILE PRINT ON MY MAINFRAME'S PRINTER? (2.3)
- --------------------------------------------------------------------
-
- Moving PostScript files between the Macintosh and other
- platforms used to be as dark an art as existed in the Macintosh
- universe. With the recent release of the LaserWriter 8 driver,
- it's no longer so complicated. You will need a PPD file
- for your printer. Many are available from ftp.adobe.com in
- /pub/adobe/PPDFiles. While their names are unfortunately
- restricted by Mess-DOS's braindead 8.3 naming convention, the file
- Filename.MAP should tell you what PPD file your printer requires.
- Be sure to select the options for PostScript Level 1 and ASCII
- text PostScript files in the Print dialog box. Finally if you're
- still having problems try using only genuine PostScript fonts, no
- TrueType or bitmapped fonts; and don't include any fonts in your
- document that already reside in the printer or on the host system.
- (Hugo Ayala's shareware control panel Trimmer will help with this
- if host available fonts are other than the standard 13 which the
- LaserWriter 8 driver has an option to omit.)
-
- Unfortunately the LaserWriter 8.1 driver is incompatible with
- a LOT of important software like most Aldus products, Canvas,
- and QuarkXPress. Until these incompatibilities are fixed you
- may need to continue using an older version of the LaserWriter
- driver. In this case you should experiment with your combination
- of application software, LaserWriter driver, and printer to see what
- works best. If you're using the System 6 LaserWriter driver, try
- using Command-K instead of K to create the PostScript file in which
- the Laser Prep header is included. The System 7 LaserWriter drivers
- include this header automatically though Hugo Ayala's shareware
- Control Panel device Trimmer will leave it out. More importantly
- Trimmer also lets you select which fonts to include in your
- PostScript file. Try using only genuine PostScript fonts,
- no TrueType or bitmapped fonts; and don't include any fonts in your
- document that already reside in the printer or on the host system.
- The freeware DMM-LaserWriter Stuff can customize your pre-8.0
- LaserWriter drivers in several different, useful ways. Among other
- possibilities this package can modify a LaserWriter driver so that
- the PostScript files it creates are more compatible with non-Apple
- printers and printing to disk is the default. The upload to the
- mainframe from which the PostScript file will be printed may also
- make a difference. Normally you need to transfer the file in pure
- Binary format, neither MacBinary nor ASCII.
-
-
- WHY ARE MY POSTSCRIPT FILES SO BIG? (2.4)
- ------------------------------------------
-
- Versions 7.0 and later of the LaserWriter driver automatically
- include all the fonts you use in your document plus the LaserPrep
- information plus the TrueType engine (if you're using any TrueType
- fonts) in the PostScript file. Thus a 3K document formatted in 90K
- of fonts can easily produce a 300K PostScript file. If these fonts
- are present on the system you'll be printing from, they don't need
- to be included in the document. You can remove them with the
- shareware control panel Trimmer or the free utility StripFonts.
- If you're using the LaserWriter 8 driver, you can manually select
- an option to leave out all fonts or just the standard thirteen
- faces of Times, Courier, Helvetica, and Symbol though for more
- control you'll still need StripFonts or Trimmer.
-
-
- HOW CAN I PRINT POSTSCRIPT ON A NON-POSTSCRIPT PRINTER? (2.5)
- --------------------------------------------------------------
-
- You need one of the payware applications Freedom of the Press
- or TScript. For most users who only want to print to common
- printers like DeskWriters, StyleWriters, or Personal LaserWriter
- LS's, the Light version of Freedom of the Press or the Basic
- version of TScript will suffice. ($55 street for either). More
- expensive versions of both products are available that work with
- more esoteric printers, particularly very-high-end color printers
- and imagesetters.
-
-
- HOW DO I MAKE MY IMAGEWRITER II PRINT IN COLOR? (2.6)
- ------------------------------------------------------
-
- Applications such as SuperPaint 2.0 and MacWrite II that
- support the original eight-color model for QuickDraw graphics only
- need a color ribbon to print in color. The shareware GIFConverter
- can open and print a variety of graphics file types in excellent
- dithered color. Jeff Skaitsis's $1 shareware CheapColor can also
- dither PixelPaint and PICT2 files on an ImageWriter II.
-
- If you have a Macintosh with a 68020 or better CPU, the
- payware MacPalette II provides general purpose color printing
- from any application that prints on a QuickDraw printer (e.g. NOT
- Illustrator). MacPalette II is about $45 street. If you need
- more information the publisher, Microspot, can be contacted
- at (800) 622-7568.
-
-
- WHY DOESN'T PRINTMONITOR WORK WITH THE IMAGEWRITER? (2.7)
- ----------------------------------------------------------
-
- Ask the Apple Customer Assistance Center (20525 Mariani Avenue,
- Cupertino, CA 95014, USA, (800) 776-2333) this one. Meanwhile
- the above-mentioned MacPalette II provides background printing
- on an ImageWriter under System 7 and a 68020 or better CPU.
- SuperLaserSpool works with lesser Macs as well. These are fully
- commercial products. There are NO freeware, shareware, or other
- ftpable solutions that work under System 7 so get out your credit
- cards. At $98 street price for SuperLaserSpool and $45 for
- MacPalette but only $300 for a vastly superior DeskWriter or
- StyleWriter II you may want to forgo the software and buy a
- better printer instead.
-
- If you're still using System 6 and have no plans to move to
- System 7, there is a shareware product called MultiSpool from Italy;
- but it is not System 7 compatible and prints only under MultiFinder.
-
-
- WHY DID MY DOCUMENT CHANGE WHEN I PRINTED IT ON SOMEONE ELSE'S PRINTER? (2.8)
- ------------------------------------------------------------------------------
-
- There are many different reasons this can happen. Far and away
- the most common problem is using the wrong printer driver. BEFORE
- you start formatting your document, make sure you have a printer
- driver for the printer you'll use for the final draft in your system
- folder and have selected that printer in the Chooser. Then choose
- Page Setup... from the File menu to let the application know what
- sort of output it should try to match the display to.
-
- The second most common problem is font confusion. Make sure
- you know exactly which fonts are in your document; and, if you're
- printing to a PostScript printer, make sure PostScript versions of
- these fonts are available to that printer. On newer printers you
- might also be able to use TrueType fonts; but PostScript is still
- the standard, especially if you're eventually going to Lino for
- camera ready output.
-
- The third most common source of trouble is poor formatting,
- especially in Microsoft Word. The Mac is not a typewriter, and
- you shouldn't use it as one. Don't use tabs as a substitute for
- indentation; don't force a page break with carriage returns; and
- NEVER use spaces to position anything. If you're writing a resume
- (by far the most common source of formatting problems for Word
- users), give serious thought to using the well-formatted resume
- template that comes with Word to help you avoid problems with
- your final printout.
-
-
- IS THERE A UTILITY TO PREVIEW POSTSCRIPT FILES ON THE MAC? (2.9)
- -----------------------------------------------------------------
-
- Net godhood awaits the first person to write a working shareware
- or freeware PostScript previewer for the Mac. The payware product
- TScript allows viewing PostScript files on the Mac, but this is a
- large package with other purposes and even the light version costs
- over $50.
-
-
- CAN I ATTACH A LASERJET OR OTHER PC PRINTER TO MY MAC? (2.10)
- --------------------------------------------------------------
-
- If your printer isn't a PostScript printer with an AppleTalk
- interface, you need either PowerPrint from GDT Softworks or the
- Grappler from Orange Micro. Both include the necessary printer
- drivers and serial to parallel cable to connect a macintosh with
- any common PC printer including HP LaserJets and DeskJets and
- Canon BubbleJets. If your printer is uncommon you can always
- ask the vendors before ordering. Both packages have street
- prices around $95.
-
-
- HOW CAN I PRINT GREY SCALES ON MY STYLEWRITER I? (2.11)
- --------------------------------------------------------
-
- The StyleWriter II driver 1.2 works with the
- StyleWriter I and will print greys. You can ftp it
- from ftp.apple.com where it's stored on the disk image
- /dts/mac/sys.soft/imaging/stylewriter-ii-install.hqx. You'll need
- to manually install it because the installer script expects all
- four disks to be available. Alternately you can retrieve it from
- the Apple Higher Education Gopher Server at info.hed.apple.com.
- The path, once there, is "USA Service, Support, and
- Training/Apple Software Updates/Printing Software." The printer
- driver is Stylewriter II v1.2.sea.hqx. Updated versions of
- Print Monitor and Printer Share are also available.
-
- When printing on a StyleWriter I with this driver, be sure
- not to select the Clean Print Head option in the Print Options
- dialog box. This damages the print head of the StyleWriter I.
- The StyleWriter I+ patch (available on mac.archive.umich.edu,
- in util/print) will remove StyleWriter II specific code from the
- driver including the option to clean the print head.
-

- ======================
- DOS AND THE MAC (3.0)
- ======================
-
- HOW CAN I MOVE FILES BETWEEN A MAC AND A PC? (3.1)
- ---------------------------------------------------
-
- The simplest way to move files between a PC and a Mac is with
- a null-modem cable and a reliable communications program. You can
- get a null-modem cable from any good electronics store. Make sure
- the cable you buy has the appropriate connectors for the Mac and PC
- you'll be connecting. Hook one end of the cable to the printer or
- modem port on your Mac and the other to a serial port on the PC.
- This should work just like a very high speed (57,600 bps) modem
- connection except that you'll probably need to turn on local echo
- in your communications program.
-
- If the computers aren't within cabling distance, you can either
- upload the files to an intermediary mainframe or put them on a
- floppy disk. The Superdrive sold since the introduction of the
- IIx is capable of formatting and writing to 3.5 inch PC floppies.
- Apple includes Apple File Exchange, a minimal program capable of
- doing this as part of the system software. Apple File Exchange
- is difficult to use and violates at least half of Apple's user
- interface guidelines. (Can anyone explain why no other software
- company violates as many of Apple's user interface guidelines
- as Apple itself does?) For details on its use please Read the
- Friendly Manual.
-
- If you frequently need to use DOS floppies and you have a
- Superdrive, you may want to invest in a more transparent solution.
- The three currently available are AccessPC from Insignia Solutions,
- DOS Mounter from Dayna, and Macintosh PC Exchange from Apple, all
- of which automatically mount and format 3.5 inch DOS floppies in a
- Superdrive without requiring you to run a separate program before
- you insert the disk. Macintosh PC Exchange requires System 7. If
- you use DOS Mounter be sure to increase your Disk cache (RAM cache
- in System 6) to at least 256K. This will substantially improve
- its performance.
-
-
- HOW CAN I TRANSLATE FILES TO A DIFFERENT PLATFORM? (3.2)
- ---------------------------------------------------------
-
- With the increasing popularity of cross-platform development,
- many Macintosh programs like Adobe Illustrator 5.0, Adobe PhotoShop,
- and Microsoft Word 5.1 are able to save directly to a format readable
- by DOS or Windows programs. You'll still need to mount the DOS
- floppies in the Mac drive using one of the products discussed above
- or do a default translation from within Apple File Exchange.
-
- Although translators for Apple File Exchange could theoretically
- be designed to translate files made by applications without these
- capabilities, AFE has never really caught on. The best solution is
- a payware product by DataViz called MacLink Plus. MacLink Plus,
- about $70 street price, can translate over 1000 DOS, Windows,
- Macintosh, and NeXT formats back and forth. For $25 more the Pro
- version comes bundled with a copy of Macintosh PC Exchange.
-
-
- SHOULD I BUY SOFTPC OR A REAL PC? (3.3)
- ----------------------------------------
-
- The various versions of SoftPC will run most DOS software on a
- Macintosh as advertised; but even on the fastest Macs, SoftPC will
- be at most as fast as an original AT. This may be adequate for
- text based software but graphics-oriented programs like most
- games will slow to a crawl. On any Mac slower than an LC III,
- performance will be at best twice the speed of an original XT. More
- likely you'll only equal the speed of an original XT. For today's
- software like WordPerfect 6.0 that's S...L...O...W.
-
- Of course slow is relative. I've seen an Amiga running a Mac
- emulator running SoftPC running a CP/M emulator. That's slow. As
- part of testing the 486 chip design, Intel ran DOS on a simulation
- of the 486 chip running on an IBM 3090 mainframe. It took them
- TWO WEEKS to get to the C> prompt! That's slow. SoftPC on a
- Classic is actually about as fast as the original IBM PC from
- ten years ago.
-
- SoftPC comes in three versions, SoftPC 3.0, SoftPC Professional
- 3.1 and SoftPC 3.1 with Windows. All versions of SoftPC run DOS 5.0
- and emulate an 80286 with an 80287 math coprocessor, support extended
- memory, and let you copy and paste between DOS and Mac programs.
- SoftPC 3.0 ($99 street) supports 16 color EGA graphics. SoftPC
- Professional 3.1 ($185 street) requires a 68030 Mac, adds support
- for 256 color VGA graphics and expanded memory, and includes Netware
- client software. SoftPC with Windows 3.1 ($299 street) requires a
- 68040 Mac with at least 10 megs of RAM and fourteen megs of free
- hard disk space (plus any disk space you want to allocate to DOS and
- Windows files). It includes all of the above plus Windows 3.1 and
- is optimized to make Windows performance tolerable (if not exactly
- speedy) on a fast Mac. If you already have the necessary hardware
- and disk space, it actually may be cheaper at current street prices
- to buy SoftPC than an equivalent PC clone. For someane with a 68040
- Mac and a lot of memory and hard disk space plus only an occasional
- need to run DOS or Windows, SoftPC is a reasonable choice.

- HOW CAN I PASSWORD PROTECT A MAC? (4.1)
- ----------------------------------------
-
- A number of payware, shareware and freeware products exist
- for the purpose of preventing a Mac from being accessed without
- a password. Some of the more easily defeated products, mostly
- shareware, use a system extension or startup application to display
- a splash screen that doesn't go away until the proper password is
- entered. Most of these can be bypassed by any of several methods
- including booting off a floppy or a different SCSI device,
- disabling extensions with the Shift key at Startup, or even
- dropping into the built-in debugger.
-
- Products that are more difficult to defeat (mostly payware)
- don't allow a hard disk to be mounted until the proper password
- is entered. Most of these can be defeated by loading a different
- driver with a hard disk formatter like FWB's Hard Disk Toolkit
- after booting from a floppy. No program of this type provides
- hacker-proof security. Nonetheless the better programs do provide
- a minimum level of protection from casual snoopers or intruders.
-
- Art Schumer's MacPassword 3.9.2 is the cheapest ($35) program
- worthy of consideration in this category. A demo version which
- expires after sixty days and isn't quite as secure is available
- for anonywous FTP. Some hard disk formatters also offer optional
- password protection. Notable in this category is FWB's Hard Disk
- Toolkit Personal Edition, about $50 mail-order.
-
- A number of payware utilities are capable of this and much
- more. My choice of commercial products in this category is Citadel
- from Datawatch ($60 street). Citadel is a complete Macintosh
- security program that provides password protection for hard disks,
- file and folder protection via DES encryption, screen locking, and
- the best protection I've ever seen against accidentally locking
- yourself out of your hard drive while still keeping intruders out.
- It's not totally intruder-proof, (No such product is.) but it does
- provide more reliable protection and more value for the money than
- any similar product I'm aware of.
-
-
- HOW CAN I PASSWORD PROTECT A FILE? (4.2)
- -----------------------------------------
-
- The best (and in many ways only) means of protecting a
- sensitive file from prying eyes is encryption. Many encryption
- utilities are available on the net and as part of various payware
- products. Most will keep out the casual snooper, but fail miserably
- when faced with a knowledgable and determined hacker. All but one
- fail in the face of an attack by an organization with the resources
- of a large corporation or government.
-
- For basic protection I recommend using DES encryption. Several
- payware and freeware products do this including the above mentioned
- Citadel and J. Clarke Stevens' $10 shareware MacEncrypt. DES is
- not unbreakable, but a brute-force attack requires an investment in
- the seven figure range. The DES algorithm has withstood the test
- of time, and it's unlikely that any "holes" exist in the algorithm
- which would allow a cheaper or faster attack provided reasonable
- intelligence is used in the choice of passwords. (i.e. don't use
- any variant of a proper name or any word which can be found in a
- dictionary as a password.)
-
- If you truly are worried about an organization with seven
- figure resources trying to break into your files, you need an
- encoder that uses a more secure version of DES with a larger
- keyspace. Currently there is exactly one such product for the Mac,
- CryptoMactic from Kent Marsh, about $56 street. Its Triple-DES
- encryption is the most secure protection you can buy off the shelf.
-
-
- HOW CAN I PASSWORD PROTECT A FOLDER? (4.3)
- -------------------------------------------
-
- A first line of defense would be to use ResEdit, DiskTop, or
- a similar tool to set the invisible, locked, and nocopy bits on the
- folders, applications, and documents you want to protect. If there
- are files in the protected folder that need to be accessed, you
- can put aliases to them in the Apple menu items folder or use an
- application and document launcher like Apollo to grant access to
- them. This won't stop a knowledgeable or determined hacker, and
- protecting the system folder in this fashion may cause problems
- under System 7; but it will cure 95% of your
- random-user-moving-things-around problems.
-
- If you want to lock out more sophisticated users, you may want
- to consider Empower II from Magna ($155 street). Art Schumer's
- MacPassword ($35 demoware) can also protect folders but only allows
- one password for all the folders it protects. Thus you can't
- grant different access levels to different people. You might also
- consider David Davies-Payne's $10 shareware SoftLock, a utility
- that can make a disk read only. However this can cause problems
- with some applications that can't run from a read-only disk.
-
-
- HOW CAN I PREVENT SOFTWARE PIRACY? (4.4)
- -----------------------------------------
-
- Novice pirates may be stymied by simply setting the nocopy bit
- on an application or by storing an application on a server and only
- granting read privileges to it. However anyone who's been around
- Macs for more than a week knows that StuffIt, Compact Pro, or any
- of a dozen other utilites can copy read-only files. However for a
- stand-alone Mac that's used by multiple individuals this may be the
- best you can do.
-
- However for more reliable protection of software on networked
- Macs consider KeyServer from Sassafras Software. KeyServer
- installs special code into each protected application so that it
- won't run without a key obtained from a server. Thus a pirate
- may be able to copy an application but won't be able to use it.
- KeyServer asymptotically costs about $20 per protected Mac which
- may seem a little expensive just to prevent piracy, but KeyServer
- also works as a license manager. The number of available keys can
- be set at the server so that only as many keys for a given package
- as you have legal licenses will be passed out. Therefore you anly
- need to buy as many copies of applications as will actually be in
- use at any given time, not as many as you have Macs. KeyServer will
- more than pay for itself the next time you upgrade or purchase new
- software. You can get a demo version of KeyServer and various
- sales propaganda and pricing info by sending E-mail to
- sassafras@dartmouth.edu.
-
-
- HOW CAN I KEEP A HARD DRIVE IN A FIXED CONFIGURATION? (4.5)
- ------------------------------------------------------------
-
- Steve Jobs designed the Macintosh with the implicit philosophy
- (which became explicit when he founded Next) of "one person, at
- least one CPU." A Mac is intended to be easily customizable and
- configurable which while fun does not readily lend itself to
- reliability in a lab based environment where users love to install
- their favorite TrueType fonts to crash your color PostScript
- printer, pirated applications to annoy the SPA, RAM hogging
- extensions that play the 1984 Quicktime movie in a continuous loop
- as wallpaper and two megabyte System beeps illegally sampled from
- Star Trek. On stand-alone Macs you probably can't do better than
- setting the locked bit of files and folders you want to protect and
- praying. If you have a Syquest or Bernoulli drive, store a copy of
- the hard disk the way it ought to be on a cartridge and use that to
- restore the disk to the desired state.
-
- If the Mac is attached to a network, however, then Purdue
- University's freeware RevRDist can automate the process of
- restoring the hard drives of any number of Macs to desired
- configurations at specified times. It can replace modified files
- with original copies, delete unwanted files, install new software,
- replace old software that may have been disabled, reset preference
- files, and in short take care of just about anything that depends
- on the presence, absence, location or contents of specific files
- (which is almost everything). RevRDist is completely configurable
- and even comes with source code so you can modify it in the
- unlikely event it doesn't do exactly what you want. RevRdist does
- not offer specific protection against destructive users it but
- does make provisions for running off a floppy so in a worst case
- scenario a hard drive can be rebuilt automatically after
- booting off a specially prepared floppy.

-
- HOW CAN I COPY A TRACK FROM AN AUDIO CD ONTO MY MAC? (5.1)
- -----------------------------------------------------------
-
- First you MUST have an Apple CD-300 or CD-300i. No other
- CD player currently available lets you save audio tracks (though this
- will likely change in the future). Next you need Quicktime 1.6.1 and
- an application that can play Quicktime movies such as Simple Player.
- Turn virtual memory off, put the CD in the CD player, and choose
- Open... from the File menu of Simple Player. Open the audio track
- you want and click Convert. Type a name for the new movie,
- choose a place to save it, and click save.
-
-
- HOW CAN I EXTRACT A SOUND FROM A QUICKTIME MOVIE? (5.2)

- sound conversion utility which converts to and from Mac sound files
- and Windows .wav files. It also converts Soundblaster .voc files,
- UNIX .au files, and AMIGA AIFF files to Macintosh sound files.
- MacTracker 1.00 and SoundTrecker 2.0 will play and convert Amiga

-
- ARE THERE ANY GOOD BOOKS ABOUT THE MAC? (6.1)
- ----------------------------------------------
-
- While there are a number of excellent books covering specific
- software packages, there are not many books that are generally
- useful to someone familiar with the net. The Mac is Not a
- TypeWriter by Robin Williams and The Macintosh Bible, by Arthur
- Naiman, Sharon Zardetto Aker and a cast of hundreds are two
- exceptions. Both are published by PeachPit Press and are
- available in finer and seedier bookstores everywhere.
-
- The Mac is Not a TypeWriter should be required reading for
- anyone using a Macintosh to produce printed matter. It teaches
- the differences between typing and typography and shows you how
- to avoid looking like a moron in print.
-
- The Macintosh Bible is a reference book that's surprisingly
- enjoyable reading. It's comprehensive enough to cover most
- questions that appear in this newsgroup including the not so
- frequent ones. It also includes lots of information you
- probably need but didn't know to ask.
-
-
- HOW CAN I TAKE A PICTURE OF THE SCREEN? (6.2)
- ----------------------------------------------
-
- The Command-Shift-3 FKey that's built into all Macs will take
- a picture of the entire screen. This won't work while a menu is
- pulled down and always includes the cursor in the picture. In
- System 6 Command-Shift-3 only works with black and white monitors
- on compact Macs. The results are stored in a PICT file on the
- root level of your System disk.
-
- Nobu Toge's Flash-It, $15 shareware, will handle almost all
- your screen capture needs. It works in black and white and color
- under both System 6 and System 7, exports images to the clipboard
- or to PICT files, captures pictures when menus are down, and can
- capture either a user-selectable region or the entire screen.
-
- Baseline Publishing's Exposure Pro ($78 street) covers all the
- basics and throws in a host of editing tools besides. Sabastian
- Software offers Image Grabber ($35 street) whose features include
- timed capture, capture of the entire screen, one window, or a
- particular rectangle, and scaling of the captured image. If you
- order Image Grabber please note the spelling. It's two words,
- spelled correctly. Apparently a grammatical product name is so
- unusual that three out of three mail-order companies were unable
- to find Image Grabber in their database until I spelled it out
- for them including the space between Image and Grabber. You can
- also order it directly from the manufacturer at (206) 865-9343.
-
-
- CAN I REPLACE THE "WELCOME TO MACINTOSH" BOX WITH A PICTURE? (6.3)
- -------------------------------------------------------------------
-
- First you need an application capable of saving documents
- in Startup Screen format such as the freeware XLateGraf or the
- shareware GIFConverter. Open the graphics file you want to turn
- into a startup screen and select Save As... from the File menu.
- Then select Startup Screen as the format to save into. Name the
- new document "StartupScreen" (no space between Startup and Screen,
- both S's capitalized) and put it in the System Folder. The next
- time the Mac starts up you should see the happy Mac, followed by
- the picture.
-
-
- HOW DO I USE A PICTURE FOR MY DESKTOP? (6.4)
- ---------------------------------------------
-
- If you have a Macintosh with Color QuickDraw in ROM (Mac II and
- later machines) get the init DeskPict, available from the usual FTP
- sites. A slightly improved and less buggy version called FunPictures
- is part of the payware Now Fun. Users of compact Macs (Plus's, SE's,
- and Classics) can pick up BackDrop from sumex-aim instead. All
- of these will replace the normal Macintosh desktop pattern with a
- picture of your choosing saved in startup screen format. (See the
- previous question.) Before saving your picture in startup screen
- format be sure to convert it to the default application palette,
- or your Mac may display color combinations distorted enough to
- induce flashbacks to that Grateful Dead concert in 1976.
-
-
- WHAT IS AUTODOUBLER? MORE DISK SPACE? SPACESAVER? NOW COMPRESS? (6.5)
- -------------------------------------------------------------------------
-
- Symantec's AutoDoubler ($58 street) is a utility that
- automatically compresses and decompresses most files on your hard
- disk so that you can store more files on it than you'd otherwise
- have room for. Ideally you won't know it's present once you've
- installed it which also means you won't have much control over
- which files are compressed. The consensus of the net is that
- AutoDoubler is fast and safe. The only common, known conflicts
- are with GateKeeper, the Find File function in Microsoft Word 5.x,
- and A/UX. If you use AutoDoubler, use Disinfectant rather than
- GateKeeper. AutoDoubler is completely incompatible with A/UX. Don't
- use AutoDoubler on an A/UX formatted partition. Word's Find File
- will work on an autodoubled volume, but you need to set it to
- find all files, not just certain types.
-
- DiskDoubler, $52 street, also from Symantec, is a
- cross between AutoDoubler and Compact Pro. Like AutoDoubler
- DiskDoubler can automatically decompress files when needed, but
- the decompression isn't nearly as transparent as AutoDoubler's.
- Like Compact Pro it only compresses when and what you tell it to
- compress and can make archives for transmission via floppy or
- modem. (Please don't use it for files you submit to the net
- though. Instead use the tighter and more standard StuffIt 3.0
- format.) SuperDoubler, a bundle that combines AutoDoubler,
- DiskDoubler and CopyDoubler is available for about $80.
-
- Alysis Software's More Disk Space ($39 street) is a competing
- product similar in functionality to AutoDoubler. As well as
- transparently compressing files More Disk Space can also make
- self-extracting and segmented archives for transmission via modem
- or floppy disk. More Disk Space has several unique features that
- make it more suitable for use on a network than competing products
- such as a freeware init that allows all Macs to use files
- previously compressed by More Disk Space as transparently as if
- More Disk Space itself were installed and the ability to create a
- "compression server" that can compress files for all Macs on the
- network on demand. Thus a network of several dozen Macs could
- use one $39 copy of More Disk Space. More Disk Space uses the
- fastest compressor/decompressor on the market, but MDS also saves
- substantially less space than the other products. More importantly
- More Disk Space relies on undocumented features of the system which
- will go away in future system software. I recommend against using
- More Disk Space.
-
- Now Compress ($62) is the latest entry into the increasingly
- crowded compression arena. It offers automatic and on-demand
- transparent compression plus archiving compression that's on a par
- with StuffIt's. Now Compress is fast enough that I don't notice
- it's installed (as are AutoDoubler and More Disk Space) which is the
- point where I decide it's not worth my effort to run detailed timing
- comparisons. Now Compress does compress tighter and thus save more
- space than any of the competing products. Furthermore it's the only
- file-level program that will transparently compress almost anything
- in the System Folder. This is important for those of us with five
- megabytes of indispensable After Dark modules. :-) I myself use and
- recommend Now Compress. It's as fast or faster than its competitors;
- (except for More Disk Space which has too many other problems to be
- seriously considered) and it frees up more space on a typical hard
- drive than any competing product. The recent 1.0.1 release has
- fixed all known incompatibilities.
-
- At 60% of the price of Now Compress SpaceSaver ($35) from
- Aladdin Systems is also a good value, especially since it can
- create and expand net standard .sit files thus serving both
- archiving and transparent compression needs. The compression is
- fast although it's not as tight as the competition's. SpaceSaver
- does give up some speed by decompressing applications onto disk
- rather than straight into RAM like other compressors. This may
- improve compatibility with future systems but slows decompression
- and contributes to file fragmentation, especially on very full
- disks. Documents normally need to be decompressed onto disk
- regardless of compressor, and SpaceSaver is faster than most for
- compressing and decompressing documents. However since any form
- of compression reduces redundancy in data and makes corruption
- of files more likely, I don't compress my document files. Since
- application files don't change nearly as often and since I'm
- therefore a lot more likely to have multiple backups of them,
- I feel much safer only compressing applications. But if you
- do compress your documents, SpaceSaver is quite competitive.
- SpaceSaver's only known major incompatibilities are with Norton
- Utilities' Directory Assistance II, MacPassword, Empower II, and
- SuperATM. Symantec has promised to fix the Directory Assistance
- Conflict in the next upgrade to the Norton Utilities, and a ResEdit
- fix is available on request from Aladdin. The incompatibility with
- SuperATM can be cured merely by renaming SpaceSaver ~SpaceSaver so
- it loads after SuperATM. MacPassword and Empower II are just not
- compatible with SpaceSaver.
-
-
- HOW DO THEY COMPARE TO TIMESTWO, STACKER, AND eDISK? (6.6)
- -----------------------------------------------------------
-
- Golden Triangle's TimesTwo ($83 street) is a unique hard disk
- driver backed by a misleading advertising campaign. Unlike the
- file-level compressors discussed in the previous section TimesTwo
- is not an init that patches the file system. Rather it is a hard
- disk driver similar to Drive7 or HardDisk Toolkit. After a disk is
- formatted with TimesTwo the Finder will report the disk as twice
- the size it actually is; e.g. a forty megabyte disk will seem to
- be an eighty megabyte disk. TimesTwo then uses compression to try
- to fit eighty megabytes of data into the forty megabytes that's
- really there. If it can't compress well enough to fit the eighty
- megabytes of data it promises (and it generally can't), it creates
- a phantom file to take up the space it overestimated. All data
- written to the disk will be automatically compressed. This is
- the exact opposite of the marketdroid promises that TimesTwo works
- without compressing anything. In fact it compresses everything.
-
- Stacker ($95) and eDisk ($62) work similarly to Times Two, the
- main difference being that they are added on top of your current
- hard disk driver rather than in place of it. This may allow you to
- retain the partitions and other features of your current driver if
- it's one Stacker or Edisk is compatible with. However both are
- incompatible with a number of other driver level programs including
- several disk formatters and security programs, most notably the
- latest Apple driver for asynchronous mode on the 68040 Macs.
- Alysis has made a very functional version of eDisk available
- for anonymous ftp. The only restriction is that it
- compresses at most 3-2. You can find it at sumex in
- the Compress-Translate directory.
-
- Driver level compressors allegedly increase disk savings
- by compressing everything whereas file level compressors exclude
- certain frequently accessed files like the desktop file, most
- things in the System Folder, and the hard disk data structures
- from compression. However the existing file-level compressors use
- more efficient compression algorithms than existing driver level
- compressors so they normally save you as much or even more space.
- Furthermore the exclusion of frequently accessed files from
- compression vastly improves the speed of file-level compressed
- disks. Under driver level compression since every file needs to be
- decompressed when read or compressed when written, a driver-level
- compressed disk is noticeably slower than the same Mac with a
- non-compressed disk or even a Mac whose disk has been compressed
- with a file level compressor. As one Apple VAR put it, "installing
- TimesTwo is like dipping your drive in molasses." Stacker and
- eDisk have equally high coefficients of virtual viscosity. Driver
- level compressors are more popular in the PC world where its common
- to find a fast 486 CPU driving a slow IDE hard disk so that the
- time savings from reading fewer physical blocks outweigh the time
- lost doing decompression. In the Macintosh world the opposite
- situation, a fast SCSI disk coexisting with a slow 68000 CPU,
- is more common so driver level compression doesn't work as well.
-
- Using a file-level compressor on a disk already compressed
- by one of these products will gain little if any space and will
- probably cut your disk access speed in half again so you should
- use either driver-level or file-level compression, not both.
-
- All the transparent compression programs have had a number of
- bugs and incompatibilities in their initial releases; and TimesTwo
- Stacker, and eDisk are no exceptions. Unlike the file-level
- programs, however, there have been a number of reports that the
- first releases of all three of these utilities have caused data
- loss and even corruption of entire hard disks. It is as yet unknown
- whether these bugs are fixed in more recent versions. Given the
- known incompatibilities, guaranteed speed loss, and significant
- risk of data corruption associated with driver level compression, I
- recommend that you do not use any of these products at this time.

- WHERE CAN I FIND THE 1984 QUICKTIME MOVIE? (6.9)
- -------------------------------------------------
-
- Try csc.ucs.uwplatt.edu [137.104.128.241] between 8 P.M. and
- 6 A.M. Central Standard Time. It's stored in /Quicktime/1984. The
- total file is 13.9 megabytes though it's split into five StuffIt
- segments of about 2.9 megabytes each. Be sure to ftp it in Binary
- mode, not the usual default of ASCII. This site has several other
- popular Quicktime movies including a recent Saturday Night Live
- "Newton" commercial.
-
-
- DO RAM DOUBLER AND OPTIMEM WORK? (6.10)
- ----------------------------------------
-
- Connectix's RAM Doubler ($50 street) uses the PMMU on 68030 and
- 68040 Macs to fool the system into believing the Mac has twice as
- much memory as it actually has. RAM Doubler provides the extra
- memory through a combination of compressing data in RAM, letting
- applications borrow memory from other programs that aren't using
- their full allotment, and storing data that would normally be in
- RAM on the hard disk. RAM Doubler requires System 7 or later. It
- performs as advertised, providing more RAM for your applications.
- RAM Doubler does this more efficiently and with less speed penalty
- than virtual memory (which can't be used at the same time as RAM
- Doubler) though most Macs do slow down by 5-10% when using it. RAM
- Doubler works better with multiple applications than with a single
- memory hog like Photoshop. Rule of thumb: For best performance
- the memory used by the system plus the largest application
- partition should be less than or equal to your physical RAM size.
-
- Ideally RAM Doubler will be transparent to your system, but
- there are incompatibilities between it and some applications and
- extensions. In particular you should watch out for extensions like
- CopyDoubler or SpeedyFinder which can slow your system to a crawl
- when they try to use all the extra RAM they think they have (but
- really don't) for caching files. RAM Doubler is also incompatible
- with the various development versions of MacsBug 6.3. It works
- with MacsBug 6.2.2. If you must use a development version of
- MacsBug, use 6.5d4 or later and change MacsBug's version from
- "development" to "final" with ResEdit. In general if an
- application works with virtual memory, it should work with
- RAM Doubler. Finally RAM Doubler doesn't yet work on PowerMacs.
-
- The Jump Development's Group Optimem is a more expensive
- ($80 street) competing product. Optimem doesn't increase available
- memory like RAM Doubler does. Instead it forces applications to
- make more efficient use of the memory they have. Optimem doles out
- RAM to applications only as they need it rather than allocating
- fixed size partitions at startup like the Finder normally does.
- Go to the Finder and look at About this Macintosh... in the Apple
- menu. All the light blue (or white on a black and white monitor)
- space in the bar beside each application is RAM that application
- has been allocated but isn't using. Optimem makes that memory
- available to other applications. In effect it forces them to share.
- If you have a lot of white space in your memory bars, then Optimem
- can help you. If you don't then RAM Doubler is certainly a better
- choice. OptiMem and RAM Doubler may be used together. However this
- is going to turn RAM Doubler into little more than another version
- of virtual memory since it does its RAM compression tricks using
- allocated but unused space while Optimem eliminates that space.
- Since Optimem is less transparent than RAM Doubler, Optimem is
- incompatible with more applications. Optimem can, however, be
- disabled on an application by application basis.
-
-
- I'M GREEDY. CAN I TRIPLE MY RAM? (6.11)
- -----------------------------------------
-
- You'll need RAM Doubler 1.0.1 for this trick. (1.0 doesn't
- have the 'pref' resource you'll need to alter.) Turn RAM doubler
- off and reboot your Mac. Then open RAM Doubler with ResEdit. Next
- open its 'pref' resource. This resource contains several fields.
- The one you want is called "multiplier value." This field contains
- one hexadecimal fixed point number, 00020000. Change it to 00030000
- for a RAM tripler, 00040000 for a RAM quadrupler, and so on. Then
- restart twice. You will now have even more RAM. Of course the the
- more RAM you ask for, the more likely it becomes that RAM Doubler
- will need to use virtual memory to meet your RAM demands thus slowing
- down your Mac.
-
- You can also use fractional multipliers as long as you remember
- that the number in the 'pref' resource is a hexadecimal fixed point
- number with the "hexidecimal point" between the second and third
- bytes. For example two and a half would be 00028000 which would
- make a "RAM Double-and-a-halfer"
-

- HOW DO I RUN SOFTWARE THAT NEEDS AN FPU ON A MAC THAT DOESN'T HAVE ONE? (6.12)

- John Neil's $10 shareware extension Software FPU will emulate a
- floating point coprocessor on an FPUless 68020 or 68030. This will
- let most (though not all) software that requires an FPU run, albeit
- somewhat slowly. Software FPU does not work on 68000 Macs. Version
- 2.44 will let some programs work on a 68LC040 Mac like the Quadra
- 605, but due to a bug in the 68LC040 chip many programs may crash.
- You'll need to test each program you use for compatibility.
- Motorola may release a fixed version of the 68LC040 sometime in
- the second quarter of 1994. Software FPU is MUCH slower than a
- real FPU. It will not improve floating point performance for
- applications that do not absolutely require an FPU. Finally note
- that an earlier version of the same program called "PseudoFPU" is
- still available at some archives. This is inferior to the current
- version of Software FPU and should not be used.
