Frequently Asked Questions about the Mac OS 8.5.x Memory Bug Patch
----------------
Q: I can no longer connect to my ISP and/or use TCP/IP and/or use AppleTalk after
applying the patch.
A: To date, two people owning blue & white G3s have reported this problem. I am not
sure what causes this and suggest that you use the patch with extra caution (or not
at all) if you have a blue & white G3.
----------------
Q: TechTool and/or TechTool Pro report my System file as "damaged" after applying the
patch.
A: This is normal. It's is because TechTool Pro doesn't actually check the System file,
it merely compares it with an internal database, and my patch isn't in that database.
The workaround for this problem is to press and hold the Option key while clicking on
"Run" in TechTool Pro. TechTool will then list all "damaged" resources. If you are using
an up-to-date version of the TechTool DNA file, then the only item on this list should
be the "nlib" resource ID=11, which is the only thing that is modified by the patcher
(thanks to Paul Schilling for pointing this out to me).
----------------
Q: Does the patch work with my Spanish/French/Ukrainian system?
A: I have only tested it with US-English and German versions of Mac OS 8.5 and 8.5.1,
and it worked with both. This probably means that it should also work with other
OS versions that use Western language encodings and character sets. You should not use
it with versions that use other encodings or character sets, such as Cyrillic, Arabic,
Hebrew, Japanese, Chinese, or Korean.
----------------
Q: I don't want to modify my System file. Can't you release the patch as an Extension/
Init file?
A: No, I can't. Somebody else might, but I'm not familiar enough with the Mac OS system
architecture. Making a patcher is fairly easy thanks to Michael Hecht's ResCompare, but
writing an INIT file that doesn't mess up your system requires more expertise than I have.
If you follow the instructions closely, the patcher should not inflict any damage, though.
----------------
Q: The patcher refuses to work and displays an error instead.
A: This means that your System file is most likely damaged. Install a clean system and
try again.
----------------
Q: Can/Should I use this patch on OS 8 or 8.1?
A: No. The bug is only in OS 8.5 and 8.5.1. You should not use it on any other versions
of the MacOS.
----------------
Q: What weird file format is .cpt? How can I open it?
A: It's a Compact Pro file. This was a common compression format many years ago, when
StuffIt was not yet a standard. I used it because the only version of StuffIt that I
have handy is 5.1, and many people can't decompress that yet.
Compact Pro files can be decompressed with any version of StuffIt Expander from 3.0
through 5.1. If you have one of those, but still cannot expand it, rebuilding your
Desktop file should help.
----------------
Q: Can I patch my active System file?
A: Don't! You will most likely damage it. NEVER modify an active System file.
----------------
Q: Is this patch official?
A: No. It is not sanctioned by Apple. You use it at your own risk. Neither myself nor
Apple can be made responsible if you lose any data because of it.
----------------
Q: Is this patch legal?
A: Sort of. The license agreement states that modifying the software is not allowed. Now
I am not doing that, but, erm, _you_ are, if you are applying the patch.
However, if Apple asks me to remove the patch from distribution, I will of course comply.
