New Mac Pro with screen flicker on login
Hello I've just got my new Mac Pro set up with a prodisplay xdr. When I enter my password and login I am seeing my screen go momentarily black twice and also get momentarily resized, subsequently working normally.
I have never seen this in any of my Macs and I don't think it should be happening in a top of the line machine.
I can’t even get through to support. What should I do folks? Thank you.
here’s a vid
