I recently got High Sierra up and running on my Optiplex 780. It runs surprisingly smoothly. I was experiencing a black screen on wake from sleep, but did some Googling and found that for the Optiplex 780 from El Capitan up, I should NOT inject ATI, as it will result in the black screen issue. So, I turned that off. Now, on wake from sleep (when I use the power button), I get video... but the computer freezes. No mouse input, no keyboard input, no mounting of thumb drives... nothing. Wake from sleep using a peripheral (mouse or keyboard) continues to give me a black screen, even after turning off ATI injection.
Everything else on the system is running excellently... does anyone have any suggestions for how I can get past this one? My video card is a Radeon 5450, either a PowerColor or a Sapphire... not sure which. Problem reporting files attached. Thanks!
