cannot open Apple Music on my iMac

Re: "cannot open Apple Music on my iMac : I have a subscription on Music but cannot open Music on my iMac?"

You might want to try restarting your iMac (Apple Menu > Restart) and wait for the Log-in screen to log back in.

(This deletes temporary files, and often restores order if something is not working right.)

See if Music now opens ok.

Else: If you still need help: Apple support has an article online (link below) that may be helpful:

All the best :-)
