so my hackontosh is running El Capitan 10.11.6 and works just fine.

But when I tried installing my gpu, nvidia gtx 760, I get no signal to the monitor when booting up. The gpu itself is installed and it functions just fine, and when I plug the hdmi in to the motherboard, I get signal. I have tried using clover configurater but I’m not sure how to get that to work. Also, when I select to use the nvidia rather than the default OS X graphics, the computer restarts and doesn’t come back on.
I’m not sure what to do if I get no signal whatsoever when the HDMI is connected to the gpu. Anyone have any idea what I can do because I’m lost! Thanks.

The GTX 760 works out of the box with full acceleration with native drivers and NO injection.

Ok I got it to turn on now, but the only way I can get past the Apple logo is by using nv_disable=1, otherwise the computer blacks out. Also, once I get in the acceleration isn’t working and the graphics are stretched and bad quality. I can’t use apps like fcp because it says I don’t have the required graphics. I also heard that it was natively supported but it doesn’t seem to be..

Suggest you zip your entire /EFI folder and attach it.
