    In iTunes, when I try to open a movie, I just get a black screen. A couple times, I've had a dialogue box pop up saying "The selected movie won't play on your display. This movie can be played only on displays that support HDCP.” I have a 2017 15" MacBook Pro, so my hardware should be more than sufficient. I've tried doing a PRAM reset, SMC reset, and even reinstalled Mojave. Any other ideas?

    Ah, the wonders of DRM, which only punishes the innocent. HDCP is a security technology designed to prevent you copying videos, by only playing on a compatible display. If it doesn’t detect the security signal, it won’t play. I’ve had similar problems on my TV, which I traced to a loose HDMI cable - but it shouldn’t ever happen with a built in laptop screen.

    Thank you! That solved it. PRAM resets used to solve problems, not create them!
