I have a Mac Pro 5,1 running Mac OS High Sierra and I also use the 27" ACD w/ mini display port as my primary display. Is this display supported or workable at all in later versions of Mac OS? Thanks for taking a look!
Got a tip for us?

Using a nearly 10-year old one right now on a Mac Pro 5,1 with Radeon RX560 video running Mojave 10.14.6. One of my wife's cats chewed off the Magsafe cable years ago, and the screen displays some faint discoloration along the lower right corner, but otherwise it is still trucking along.
Just connected a 2019 MacBook Air running Big Sur to my 27" ADC with Mini DisplayPort to diagnose a screen issue with no problems. I used a USC-C to DisplayPort adapter that was recommended in another post.
