locally manage iphone from catalina
I want to manage files on my iphone from my Mac, but on Catalina, the Music app no longer works like the old iTunes app.
This has broken local storage, and there's no easily googleable answer. So - what's your advice on how to create local backups, swap files from apps to iphone, and the features that were removed in the switch from iTunes to Music?
Thank you for the help!
