This is going to seem like a stupid question. But, I have an NVidia GTX 690. And I guess I need to delete the graphics .kexts. So, Do I delete the NVidia ones? Or the AMD/Intel ones? Or all of them?
I have a grey screen with just a loading cursor after trying to boot. I left it for 15 minutes and it did nothing. I'm a noob, can someone help me and/or tell me what to do please?
