Many times when rebooting my MAC Mini, after it comes up & I go to Music; I click on Songs and find entire Library listed EXCEPT----- All cloud files and individual cloud emojis are greyed. So I go to preferences and Check BOX Sync Library, then I click OK. Window pops up 'To add songs and playlists to your Library, you must use Cloud Music Library. I then click on Merge Library box. BAD NEWS- DID NOT WORK. What am I doing wrong? Or what setting I have set incorrectly? (I am not an Apple Music subscriber currently} Also--- It has worked on occasions in the past but I don't understand what I did different. SOMEONE PLEASE HELP THANKS IN ADVANCE!
