Hi

Am I the only one who have troubles with iMac 2013 in Target Display Mode with another MacBook Pro?

I'll try to keep it short.
Sierra works perfect, since High Sierra(and Mojave betas) i get a black screen instead of my iMac screen when disconnecting TDM, doesn't matter if i pull the cable or press CMD+F2. I can remote connect to my iMac and control it, which surely proves its running, but with a complete black screen.

I have been in contact with Apple for months, who after multiple times with troubleshooting, now getting data from my iMac with some Support program, even talking with higher up Engineers who doesn't know what's up.

Right now i have to restart my iMac before i can use the screen again.

Does anyone have the same problems with TDM? Maybe someone knows how to fix it?
