So I have a MacPro 4,1 with a PC GTX570 and a GT120 (Use the first one for CUDA and second for bootscreen) and everything worked well with OSX 10.8

I updated to OSX 10.9 without doing much research and then realized there was no nvidia drivers. Now the drivers are there but when I try to install them the computer stays stuck at the grey boot screen and won't go past it. I have to reset the PRAM and revert to OSX default graphics driver to get the computer to boot.

Is there any way to go around this?:confused:
