I installed my Nvidia, and everything is fine except the OpenGL mode, here is screenshot:

How can i enable OpenGL, and what kexts do i use, i almost did it with Nvinject, but screen goes black and i have to delete Nvinject, this is with EfiStudio, and i don't know is this metod succeed.

Did you add the efi string to your boot.plist file? If so you don't need any kexts to make work.

i add it, there is no changes. Something else?
