nothing in my iTunes will play as my iMac says I already have 5 "machines" authorised. I don't, I only have this one...but it won't let me deauthorise either. Completely at a loss as to what to do. iMac is only a month old. Any ideas.
iMac 24″, macOS 14.3
See the 'If you need to deauthorize a computer that you don't have access to' section in:

This seems to be a bug with the latest MacOS. See:
Why can't I "Deauthorize All" in Music 1.… - Apple Community
iMac won't let me authorise it to play music despite only having 1 machine authorised
