@Stork,
Apple removed that update, we can't use that method, unless you know of another place to download the update??
I just checked, and the first link to the Apple Tech Note still works to download the 10.8.2 Supplemental Update. I updated the direct link.
BTW, I think I change my System Definition from MacMini5,1 for HD4000 to MacPro3,1 for the 650 Ti as the tonymacx86 instructions in the link above.
So : I've tried to install the update at http://support.apple.com/kb/DL1609, and to switch config between iMac12,2, iMac13,2, MacPro3,1, but I still have those "NVDA(OpenGL): Channel exception!" errors… What's more, I can't use Unigine Heaven, because I always get this error before it ends (I've never been able to get to the end of the test !). Anyone has an idea ? I have installed CUDA drivers, can it be involved, causing this error ?
Ever any final luck man??? These errors are driving me nuts, I can't let go of this card cause I paid good money and it screams in Windows.. :/
I successfully installed a GTX650 Ti, MSI's Power Edition, using Bimmer's instructions with Mountain Lion 10.8.2 on a GA-Z77X-UP4 TH with the Intel i73770K CPU last week. I did NOT install Cuda. Zero problems with any application, sleep, etc.
I recommend this methos as well. I got the 650Ti MSI Power Edition to work as well. Also, I am a newb and this is probably not the right place but how do you change the System Definitions with an already installed OS? Probably just overlooking it. . .
Awesome! Thank you for helping me out. I am on the Mac Pro 3,1 so it will be cool to update that. Seen any better results with certain ones? Guess not completely sure what would change them.
