Can't log into Music / Itunes on Mac

Hi All

I've sorted the issue.... it was a corruption of the icloud database on my Mac.

If anyone else has a similar issue try this solution shown in this thread iCloud and internet accounts broken - Apple Community

Following the instructions below worked for me.

To repair, copy and paste this command into Terminal, but do not hit enter before closing all other applications running on your computer. Once everything else is closed, go ahead and hit enter. You may be prompted to enter your administrator password because it is a sudo command, so go ahead and do that (but keep in mind that when you type your password into terminal, the text cursor will not move to show how much you have typed already). A few moments later, your computer should restart. Once it's open, you should be able to sign into iCloud and Internet Accounts as normal.

Here is the command:

sudo -v ; killall -9 accountsd com.apple.iCloudHelper ; defaults delete MobileMeAccounts ; mkdir ~/Library/Accounts/Backup ; mv ~/Library/Accounts/*.sqlite* ~/Library/Accounts/Backup/ ; killall -9 accountsd com.apple.iCloudHelper ; sudo reboot
