Hi. Ive spent a lot of time now searching around the internet for this and unfortunately havent found a solution.

I have a Mac Pro 5,1 running high sierra. Until earlier this week it had a GTX980ti running as the gpu. I had to reset the pram as part of other hardware changes, and after booting back up the gpu is no longer recognized.

Ive done this before and normally I just have to put the original gpu back in and re-enable the web drivers. But for some reason, this time I cant use the nvidia card at all. I even tried with a gtx960 as well and came up with the same issue, so it isn’t that the card is defective.

If anyone has a solution to this it would be really appreciated. Thanks!
