Hi Im getting an error message on my new iMac
This Movie cannot be played because its on a display that is not authorised to play protected movies try moving this window to a different display or disconnect any displays that are not HDCP autorised
The thing Is all my movies are bought from iTunes, this is an out the box iMac with nothing connected its the iMac screen im trying to watch the content on i've tried you tube all formats up to 4 k work fine netflix nothing works at all sd 1080p or 4k
Ive looked all over for a result on this and all i get are video converters but that can't be right this is apple stuff it should play on apple computers Ive been on to AppleCare but they think it could be the graphics card does anyone have a fix that isn't third party solution this should work out the box
running sierra non a 5k retina iMac
Thanks in advance for any help
regards
Craig
