I just noticed that some applications will always crash on the MacBook Pro 10.4.10.
The error that I encounter every time is:
Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000
similar crashes affecting either with the games or the CS3 applications or other applications in bulk and on that machine Macintel.
