Hi
I have been having an issue of black screens after updating a working Sierra install to 10.12.6.
Lucky I had a carbon copy of an El Capitan install that im able to boot into. I have been told that the GTX 780 has native support so im unsure what is going on here. My clover is not injecting any graphics at all. And my monitors are connected via DVI. After the apple logo loading screen all I get is two black screens with a mouse pointer that im able to move fine but do nothing else.
I have tried boot in verbose and also safe mode but still get the same result of the black screens.
I have spent all evening looking over threads like for the pat 8 hours and I am unsure what to do it was working fine on Sierra before the security update.
Here is my specs
