iTunes DRM Video Playback
Has anyone managed to successfully build an eGPU setup where playback of DRM videos in iTunes actually works? I have a Mac Mini late 2012 using a GTX 1060 in a Sonnet III-D connected through Thunderbolt 1. This is on macOS High Sierra 10.13.3. All I see in iTunes is that it wants to start playback but it does not actually start. I can see the progress bar of the video but it stays at 0 seconds. When I move iTunes to a monitor connected to the internal GPU playback starts. Moving it back to the eGPU iTunes complains about a HDCP issue and stops playing.
I am using both NvidiaGraphicsFixup and Shiki but those do not seem to help.
