I have a Sparkle nVidia 7300 GT gfx card. I used iAtkos v5i install DVD. When I go into system profiler, Quartz extreme isn't supported. I then went into NVinject's plist file and changed ioprobescore from 60000 to 0, restarted and it worked. However, I have since restored my OSX install because I wanted to start fresh. I tried doing the same thing to the plist file, but this time it didn't work. I'm pretty sure I'm using the same NVinject.kext i was using last time, but I'm not positive. Could the kernel have something to do with it? Any help is appreciated.
