TheRacerMaster Posted September 26, 2012 Share Posted September 26, 2012 Delete the nVidia kexts. Do not delete the Intel kexts. Optimus does not work in OS X, and people with the 540M only got it working with a BIOS patch to disable Optimus altogether. Link to comment Share on other sites More sharing options...
