I have been using my 27" iMac as the target display for my iMac Pro over the six months. But, lately, after upgrading both machines on latest macOS Mojave, target display mode stopped working.
After pressing CMD+F2, my 27" iMac goes to black blank screen. I tried restart, Log out, but nothing happens.
Any suggestions?
Thanks in advance.
Best regards.
