screen mirroring appletv+ causes black screen
I open Apple TV plus on my new iMac and start watching a movie. But when I screen mirror to my TV in the lounge the movie on the iMac goes black but with audio. The black screen mirrors to the TV as a black screen including audio on the TV. If I open a YouTube video on the iMac, it screen mirrors to the TV as expected. The error seems to be linked to trying to screen mirror Apple TV plus. I have set Mirror Built-in Retina Display.
iMac 24″, macOS 13.5
