Catalina OS: disable automatic backup iPhone, Apple Devices terminal command

If you annoyed of having to have your iPhone backed up every time you load the new Music app by Apple and sync your Apple device, please read.

As you may or may not know, iTunes is gone, that’s right, gone. More info. iTunes is dead and is being replaced with four separate apps: Music, Books, TV and Podcasts.

On previous versions, it was as simple as entering a one-line command in terminal: defaults write DeviceBackupsDisabled -bool true

As this would work on iTunes, this won’t work in the Apple Music app. Here is how you can disable automatic backup on Catalina (no iTunes) on the Music app.

Find the backup folder

Quit the music app if it’s running.

Using Finder, from the file menu select: Go > Go to Folder…
