I’ve been using Power Photos (and the software that managed iPhoto libraries before it) for years.
Now I’d love something similar for iTunes. Though I’ve not upgraded my OS to Catalina yet… but because my hard drive seems to BLOAT like crazy, I try to keep most of my music, etc, off the computer. It would be wonderful to have a library on the external hard drive on my desk and at work, but only a select few albums on the actual mac.
Any recommendations? Or is it even relevant in Catalina?
