chill will Posted July 10, 2013 Share Posted July 10, 2013 Hello I install mountain lion on my Asus P5 mother board and everything was working fine using a Nvidia 8800 video card, my video card went bad, and I replaced it with a Nvidia 650ti with 2 gigs of ram, now when I boot up mountain lion it will try to boot and just before I get to the login screen it goes black.. What do I need to do in order to get mountain lion to accept my new video card (Nvidia 650ti)? Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted July 10, 2013 Share Posted July 10, 2013 Try booting with GraphicsEnabler=n (at the Chameleon boot GUI select your OS X drive with the arrow keys, then simply start typing). If that doesn't work, let me know if you can boot with -x (safe mode, video drivers don't load) Link to comment Share on other sites More sharing options...
chill will Posted July 11, 2013 Author Share Posted July 11, 2013 Well I try both and either one would not work. I got close to the login using GraphicsEnabler=n before it locked up. -x mode same thing black screen Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted July 11, 2013 Share Posted July 11, 2013 Okay try these all at once, exactly as below, note the capitalization: UseKernelCache=n GraphicsEnabler=n -v -x Link to comment Share on other sites More sharing options...
chill will Posted July 12, 2013 Author Share Posted July 12, 2013 I try that and the same thing it will go as far last login screen, just when you type your user name and pw, and just lock up. My question is how to I delete my old Nvidia 8800 kext, and install a new<Nvidia 650ti> Kexts, when I can not boot up. Link to comment Share on other sites More sharing options...
chill will Posted July 13, 2013 Author Share Posted July 13, 2013 Ok update I was finally able to get it to boot up, the only way I can get it to boot up is to use, -v GraphicsEnabler=No, and the system is showing Nvida 650ti 2gigs Now what do I need to do to get it to boot up with out having to use -v GraphicsEnabler=No Link to comment Share on other sites More sharing options...
