Finder/Preferences/Sidebar check boxes not working
Recently two issues:
(Using Big Sur on Macbook Pro M1 with Apple external monitor. All latest updates installed.)
- The dock has disappeared twice. Latest, it seemed to be related to not closing my Macbook Pro Cover.
Not even sure what the initial cause of that was. It's okay right now.
- Right now. It seems Finder/Preferences/Sidebar is not working. Ticking boxes for Hard Drives, External drives works but nothing else is displayed. Ticking boxes for Recents, Music, iCloud, etc. has no result, although the boxes stay ticked.
MacBook Pro 13″, macOS 11.5
