Use iTunes and iCloud together on Mac
With iTunes in the Cloud, your iTunes Store purchases and iTunes music library can always be available on all your computers and iOS devices — wirelessly and without syncing. See What is iCloud “content everywhere”?
Here’s how it works: When you purchase items from the iTunes Store, they’re stored in iCloud and available to be downloaded on demand to any of your computers and devices that are connected to the internet and set up to use iCloud.
If you subscribe to Apple Music or iTunes Match, you can store all your music in your iCloud Music Library — including songs you imported from CDs and purchased from places other than the iTunes Store. You can play those songs on any of your computers or devices whenever you want.
To download any item from your iCloud Music Library to your computer, click the item’s iCloud Download button . You can view only your downloaded items by selecting Downloaded in the sidebar on the left.
Automatic downloads and downloads of past purchases are available to all iTunes Store customers. To use Apple Music or iTunes Match, you need to be a subscriber.
