Hello there,
My question pertains in part to the Mac Pro and in part to OSX and drivers. I upgraded my GPU with the newly released Mac Pro compatible Sapphire AMD Radeon HD 7950.
This card here:
Installed the drivers- running both on Windows and on Mac things ran great. Games I tested on both were defaulting to the highest possible graphic settings and my video and rendering applications were loving it.
I then updated from 10.8.2 to 10.8.3... I can't definitively say if I started having issues immediately after, but at some point for sure, my Mac side's graphics became pitiful. Expose and core OS animations were being played out in 2 or 3 frames per second, websites would flicker. VLC could no longer play videos (audio was fine) and I receive errors stating something along the lines of there being no OpenGL acceleration. When I go over to my Windows side, there is no issue at all. I repaired permissions and noted that there were anomalies listed with AMD, however the problem persists.
The system won't let me reinstall the drivers and I know of no way to uninstall them to then reinstall them.
I don't know if the problem originates with the software update, but I have no other leads.
OSX still identifies the card installed. I'm at a loss. I contacted apple and they said that they can't suggest anything (software support or otherwise) since I didn't purchase the card through their store..
Thoughts would be great. I've had to look into the hackintosh community for answers, but I'm not comfortable resorting to their solutions before being able to clearly identify the problem.
Thanks
