Now this poor old G4 tower is running 10.4.11 with an ancient Rage 128 Pro graphics card, but it handles its 17inch screen just fine at “million of colors” color depth when sitting in front of it. Once I used the color control on the ARD application to lower the color depth by 1 notch, the next connection worked just fine, with the screen showing up and behaving normally. Keyboard commands still worked (I can blindly log in from the loginwindow), though mouse movements did not pass through to the old Mac.Īfter fruitlessly chasing network issues with my AirPort router, the last post at an Apple Discussions thread pointed me to the right direction.

So, to fix the black screen issue on Microsoft Teams, remove this file. Please google how to tell the difference and then test it.
