Alright guys,
Killing some final bugs. Keep getting freezes, and I suspect they're graphics related.
Uninstalling CUDA is a pain, so I'm trying MacBook Pro 10,1 instead of MacMini 6,2.
I had patched AGPM.kext using values from another post here, and it gave me sleep but might have been responsible for my hangs. Values are as follows:
I'm starting with the native PM that the 10,1 sysdef has to see if that works. If not, maybe I'll dig CUDA out of the system or repaste the current AGMP into it.
What I really want to know (aside from general insight) is how to make AGPM edits for my card, a GTX 660. Most people have the 660 Ti, but that's a GK104 card and this is a GK106. Searching for 650 Ti Boost didn't turn up much, either.
Any other thoughts are welcome, of course.
EDIT: nooope, still crashes. Cinebench works well for making it happen. I think I'll kill CUDA next.
In a possibly unrelated matter, turning on integrated graphics (with appropriate settings/boot.plist edits) causes a hang during boot right after bluetooth initialization.
