romanvaras Posted February 7, 2017 Share Posted February 7, 2017 Hey Everybody... this is my first post here, and I just setup my first hackintosh. So, I installed Yosemite 10.10 (not with a retail image). And everything seems to be fine except for the Nvidia card which I can not activate. The OS loads with some sort of generic low res standard driver, and I am able to log in and see the desktop but it is really sluggish, you guys know what I am talking about, The first question is : How can I try different kexts, drivers, etc with the possibility of getting back the old settings. Everytime I change a thing in the nvidia/video settings or kexts the next time I reboot I can no longer see the desktop, because my screen goes off. I mean the monitor turns off as a result of the lack of video signal. So I need to recover the default OS video driver without having to reinstall all over again... The second question is : HOW IN THE WORLD can I make the Nvidia 9400GT (deviceId 0x065b) work ? I tried everything I found in this forums to no avail. Anyone can help me with a clear step by step guide ? Thanks in advance. Roman Link to comment Share on other sites More sharing options...

ea dd Posted February 16, 2017 Share Posted February 16, 2017 use Clover Configuator from http://mackie100projects.altervista.org/download-clover-configurator/ to mount EFI partitions. Follow Tools -> Mount EFI -> Efi Partitions. Link to comment Share on other sites More sharing options...
