Fix "This computer is not authorized" for songs, films and books

Why it happens

Songs, films and books bought from Apple only play on computers you've authorized with your Apple Account, and one account can authorize up to 5. A new Mac, a fresh install of macOS or a different Apple Account means this Mac isn't on your list yet. Old computers you sold still count until you remove them.

How to fix it

1. Open the Music app. If it's a film or TV show that won't play, use the TV app instead; it has the same Account menu.

2. Choose Account > Authorizations > Authorize This Computer… in the menu bar.

   Music›Account›Authorizations›Authorize This Computer…

3. Sign in with the Apple Account that bought the item and confirm. Your Mac tells you how many computers are now authorized.

4. Play the song, film or book again.

Still not fixed?

1. Told you've already authorized 5 computers? On an old Mac you still have, open Music and choose Account > Authorizations > Deauthorize This Computer…, then try again here.

   Music›Account›Authorizations›Deauthorize This Computer…

2. Old computer sold or broken? In Music, choose Account > Account Settings… and click Deauthorize All. You can only do that once a year, and then you authorize each computer you still use again.

   Music›Account›Account Settings…

3. Check you're signed in with the right Apple Account. The one shown in the Account menu has to be the one that bought the item.

4. Before you sell or give away a Mac, deauthorize it, so it doesn't keep using one of your 5.

5. If it still says not authorized after you've authorized this Mac, or Deauthorize All isn't there, contact Apple Support. They can help with your Apple Account purchases.
