Sync your Apple Music library

If you subscribe to Apple Music, Sync Library lets you access your music library and music that you’ve downloaded from Apple Music on all of your devices where you’re signed in to the same Apple Account. In the latest version of iOS, iPadOS, and macOS, Sync Library is turned on by default.

• On iPhone or iPad: Go to Settings  > Apps > Music, then make sure Sync Library is turned on.

• On Mac: Go to the Music app , choose Music > Settings, click General, then make sure Sync Library is turned on.
