iTunes freezes
iTunes freezes when I click on Recently Added. I have sign out/in and wait for updating library but still the same problem.
iMac 27" 5K, macOS 10.14
Try booting into Safe Mode, it carries out some housekeeping that may clear your issue.
Start up the Mac by holding down the Shift key, let it fully boot (it takes longer) and then after 39 seconds close down and start as normal.
