Starting up in Music on Mac
I have a Mac using Catalina 10.15.7. Used to using iTunes. Now that it's not there, I went to try out Music app, but when I click on it to open, I get the bar across the top of the screen, but nothing else. Where is the bar down the side that everyone is talking about? I tried to look under every title at the top, but none of them opens up the sidebar with the library, songs, artists, etc. What am I missing?
