Retina MacBook PRO 15 2012 w GT650m. When I play games/use high GPU demand soft, my pc start to black screen/reboot, because of GPU reaching 80'+ degrees (or to high clock/voltage). Maxout fans isn’t working. I can underclock GPU in Windows and it fixes problems. Any how to fix GPU in Mac OS? Kexts, EFI mods, Apps? Is it possible to flash GT650m’s bios, like in Windows PCs, to make it work?
