Question: No Video After Security Upgrade
I had avoided doing the upgrade for some time. Tonight i gave in. After the upgrade i lost all video. Neither of my cards will output video, standard 5770 that came with the Mac Pro or the 1050ti that i added. I am really angry. Why would Apple do this? I have done the pram/nvram thing, i have done the power cord unplug and wait thing and still no success. How do i get video back after the Apple upgrade?
Mac Pro, iOS 11.3, 32gb ram 5770 and 1050ti video
