iMac access to Music app and AppleID Setting message
I have a 2012 iMac running macOS Catalonia and have been experiencing this problem for a while now. There are actually two but I think they may be connected. System preferences keeps telling me to update Apple ID Settings, but doesn't tell me what to update. Also, Music app will not log into my account. It works fine on my ipad2 and my iPhone and on the web access, but just will not connect on my iMac. I've tried the 'redeem' hack, reseting cache and library, renaming library. My username and password are correct, it won't let me authorise the computer ('There's a temporary problem' message), tried logging in and out of iCloud, starting in safe mode. Not sure what else I can do.
iMac 21.5″, macOS 10.15
