Hey Mark, how's the CS6 going?
I am realizing I can't use Pr on my Mac Pro 2,1 as Adobe has cut off 32bit EFI support as of CS6. Bummers.
Here is a thread on Adobe forums detailing the many issues with this same exact error issue that we're experiencing. Many people have been having issues with CS6 on Macs, some that seem resolved for a month after extensive system rebuilds uninstall/reinstalls etc and the serious error comes back.
You may find this interesting, and when/if your Pr starts crashing again.
