I found this on the Quartz Composer Mailing list - I was having a
similar problem, and it turned out to be a Quartz Extreme issue:
CGDisplayUsesOpenGLAcceleration(kCGDirectMainDisplay)
Checking the above will let you know whether a user's machine is
Quartz Extreme equipped.
Hope that helps,

We're building an app that makes use of Quartz Composer (QCView,
specifically), and we would like it to be able to exit gracefully if
one tries to load it on 10.3. I've tried searching through the
documentation for strategies that deal with this, but haven't been
able to find anything. Switching the "Cross-Develop Using Target SDK"
to 10.3.9 doesn't work because it then fails when trying to find the
Quartz framework.
I was able to detect which version of the OS is running, but the app
just doesn't load on 10.3. I'm not sure if it's because of the QCView
in the nib file, or if because it was compiled with gcc 4, but I
imagine there is a proper way to do this. After all, there are apps
out there already that have Spotlight functionality if you're running
on 10.4, and which still work if you're on 10.3.
I'm guessing that I'm just not looking in the right place in the
documentation for information on how to do this because I would find
it hard to believe that Apple would overlook this important topic.
Any help/direction would be greatly appreciated.
Thanks,
Patrick
