I have successful instalation of Mavericks 10.9.2 on ASROCK 960GC-GS FX mobo, my CPU is AMD X2 5000 and I have 2GB DDR2 RAM. Everything worx except my NVidia GTX 260. I have downloaded latest Nvidia WebDrivers. Ater booting with -v the last thing I can see is NVDANV50hal... successfully loaded, and after
that just black screen, changing DVI port at graphic card does not help.
booting with IGPEnabler No does not help
I was thinking about this problem, this mobo has onboard AMD Radeon 3000 graphics, but it can not be disabled in Bios, I can just choose which graphics will be primary - PCIE was choosen.
When I use only onboard Radeon, OSX boots and can be used, but without graphical acceleration and I have not found any kext for Radeon 3000.
So that is why I am trying old but still good Nvidia GTX 260.
