Storing your Photos.app library on an external disk, that you maybe want to unmount from time to time, was always really annoying. It’s constantly “analyzing” pictures for faces or transcoding videos even if you quit the app.

What’s new is that now the new Music.app that ships with macOS Catalina has the same behavior as apparently the AMPLibrary needs to do important things all the time now.

I guess I’ll just get used to “Force Eject”.
