My app works fine on an Intel Mac running 10.5, and on my old 800 MHz
Powerbook G4 running 10.4.11. But after the latest update I received
complaints from two users with G3 processors. Upon investigation, it
turns out that the message
-[NSBundle classNamed:]
logs an error [1] and returns nil instead of loading the bundle and
returning the requested Class. If I didn't know better, I'd say this
is an apparent case of insufficient hardware to load needed
resources. But, duh, that's supposed to be impossible with virtual
memory.
One user has an iBook with a 800 MHz G3 processor and 640 MB RAM. The
other has a "Paris" Clamshell iBook with a 466 MHz G3 and RAM maxxed
out at 512 MB. She says it's "the oldest iBook that can run OS X".
Now, the user with the 800 MHz iBook has been using my app for over
two years. Also, I myself have run previous versions of my app on my
old 500 MHz G3 iBook with 320 MB RAM, 10.4.?, and it worked. (But I
have since downgraded that puppy to 10.3.9, and my app does not try to
load the problem bundle under 10.3.9.)
It looks like something got changed in the latest build that G3
processors don't like. Any ideas what that might be?

[1] The error is:
*** -[NSBundle load]:
Error loading code /Applications/MyApp.app/Contents/Resources/
BmTiger.bundle/Contents/MacOS/BmTiger
for bundle /Applications/MyApp.app/Contents/Resources/BmTiger.bundle,
error code 4
(link edit error code 4,
error number 0 (
Library not loaded:
@executable_path/../Frameworks/SSSQLiter.framework/
Versions/A/SSSQLiter
which says that the SSSQLiter framework will not load, but I checked
and it ^is^ at the promised path, and ^is^ a universal binary, and of
course this all works fine on my Powerbook G4. MyApp's package
