- IMPORTANT NEW INFORMATION
-
- The following issues are not covered in the Read Me file.
- Please read this information before installing Mac OS 7.6.1
- Update on your computer.
-
- OPEN TRANSPORT 1.1.2 AND POWERBOOK 3400
- Open Transport 1.1.2 and the PowerBook 3400 are not
- compatible unless you follow these instructions. Open
- Transport 1.1.2 was released to address issues with very
- specific network configurations of some customers, and is
- not required for most Open Transport users. If you require
- version 1.1.2 of Open Transport for your network
- configuration, first install Open Transport 1.1.2, and then
- immediately install the Mac OS 7.6.1 Update for PowerBook
- 3400. This will overwrite resources which otherwise could
- cause crashes when switching between Infrared and LocalTalk.
-
- POWERBOOK 1400 AND NEWER TECHNOLOGY ETHERNET CARD
- A PowerBook 1400 used with the Newer Technology Ethernet
- card requires Ethernet driver version 1.5 or later from
- Newer Technology. Drivers older than version 1.5 may cause
- crashes. Visit Newer Technology's web site for the latest
- version: http://newertech.com/software.html, or call their
- Tech Support at 1-800-678-3726.
-
- INFRARED CONTROL PANEL PRODUCES INCORRECT ERROR
- If the Infrared control panel is selected on a computer that
- does not have infrared capability, an error -192 message is
- displayed. The error should state that Infrared is not
- supported on this computer.
-
- PRINTING SPEED IMPROVEMENTS
- Improved print speed is present for some computers using
- third party printers over LocalTalk networks. However, Power
- Macintosh 5400 and 6400 computers with processor speeds less
- than 200 MHz without an L2 cache still exhibit slow
- printing. Apple is working on a solution to this problem,
- and will post a solution as soon possible in the same
- locations as this update.
-
- 68040 COMPUTERS AND CLOSED CAPTION FEATURE IN APPLE VIDEO
- PLAYER
- Apple Video Player's Closed Caption option will cause a hang
- on a 68040 computer with the Apple TV Tuner card installed.
- Reinstalling the Apple Video Player (version 1.4) from the
- Mac OS 7.6 CD will remedy the problem. To reinstall, launch
- "Install System Software" in the Mac OS 7.6 folder within
- the Software Installers folder on the Mac OS 7.6 CD. Choose
- "Custom Install" from the pop-up, then click on the triangle
- next to the item "Multimedia" to expand it. Select "Apple
- Video Player 1.4" and click "Install." When asked if the
- "Newer" or "Older" file should be used, select "Older."
-
- APPLE VIDEO PLAYER & MAC OS 7.6.1 INCOMPATIBLE WITH
- QUICKTIME MPEG CARD
- Apple Video Player will not properly recognize a QuickTime
- MPEG Card when run under Mac OS 7.6 or Mac OS 7.6.1. With
- Mac OS 7.6.1 the QuickTime MPEG extension can be used to
- view MPEG files using software decompression with Apple
- Video Player.
-
- APPLE VIDEO PLAYER 1.6 IS NOT INSTALLED ON POWERBOOK 3400
- If you need to use this application program, it can be
- downloaded from http://www.info.apple.com.
-
- POWER MACINTOSH 7100/80AV AND APPLE VIDEO PLAYER SOUND
- PROBLEMS
- If the sound is muted and the slider doesn't work in Apple
- Video Player on a 7100/80AV, open Apple Video Player and
- click on the mute button to activate it. Quitting and
- relaunching the Apple Video Player should then remedy the
- problem.
-
- MAC OS 7.6.1 AND APPLEVISION 1710: MISSING COLORSYNC PROFILE
- If you try to import the "AppleVision 1710-9300" ColorSync
- profile, and the error "Could not complete your request
- because a ColorSync error has occurred." appears, install
- AppleVision 1.5.1 to eliminate the problem.
-
- EXTENSIONS MANAGER'S MAC OS 7.6.1 SETS OMIT FILE NEEDED TO
- PRINT
- Selecting "Mac OS 7.6.1 Base" and "Mac OS 7.6.1 All" in
- Extensions Manager, mistakenly turns off "Printing Lib" and
- printing is disabled. Manually turning on "Printing Lib"
- within Extensions Manager after choosing one of these sets
- will allow printing.
-
- EXTENSIONS MANAGER'S MAC OS 7.6.1 SETS OMIT MONITORS CONTROL
- PANEL
- Selecting "Mac OS 7.6.1 Base" and "Mac OS 7.6.1 All" in
- Extensions Manager, mistakenly turns off "Monitors" control
- panel. Manually turning on "Monitors" within Extensions
- Manager after choosing one of these sets will allow access
- to this control panel.
-
- INTERNAL SPEAKER ON POWER MACINTOSH 5500 AND 6500 REMAIN
- MUTED
- If external speakers are connected to a Power Macintosh 5500
- or 6500 when the computer starts up and are then
- disconnected, the internal speakers remains muted. Restart
- the computer after disconnecting the external speakers and
- the internal speaker will work normally.
-
- VM IS NOT TURNED ON FOR 68030 & 68040 COMPUTERS WITH MORE
- THAN 16 MB OF RAM
- 68030- and 68040-based Macintosh computers with more than 16
- MB of physical memory do not have Virtual Memory turned on
- after installing Mac OS 7.6.1 Update.
-
- POWER MACINTOSH 5500 and 6500 SCREEN REFRESH PROBLEM WITH
- MPEG MOVIES
- Windows of MPEG movies on Power Macintosh 5500 computers may
- exhibit white areas obscuring the movie in the window.
- Removing the ATI MPEG extension from the Extensions folder,
- or manipulating the movie window will work around the
- problem.
