alien9 Posted April 28, 2015 Share Posted April 28, 2015 I am having problems with my Gigabyte Gtx 970 getting detected by Yosemite install. I have tried too many methods here and there to make it work and because I am a beginner and learning new things with each combination, I am repetitively failing to make that happen. So here are few things I did which are not working as expected: 1) I installed the appropriate drivers and tried to boot up with loading nvidia drivers from preferences center but that didn't worked. 2) I tried injectEDID, InjectNvidia and LoadVideoBios from clover bootloader option and also with the flag kext-dev-mode=1 but it failed to work. In 'about mac' it is showing gtx 970 "0"mb vram. Monitor works so slow that I can distinctly see each buffer and screen refresh every time. 3) I used additional boot flag nvda_drv=1 to make it detect the VRAM of the GPU but after the apple logo, monitor went black showing "NO SIGNAL" error where I have turn off the power supply to restart the system. Please would anyone guide me to make my 970 work with Yosemite.
