iTunes Store: Authorize or deauthorize your Mac or PC
You can manage which computers sync or use apps, audiobooks, books, music, movies, and other content you purchase from the iTunes Store by authorizing or deauthorizing your Mac or PC. If your computer isn't working or you don't have it anymore, you can also deauthorize all your computers from the iTunes Store.
Authorize a Mac or PC
Review the following before you authorize a computer:
- You can authorize up to five computers with your Apple ID.
- You must authorize your computer to download past purchases, use Home Sharing, or use the Automatic Downloads setting.
- You can play unprotected music that's in the AAC file format without authorizing your computer. This includes iTunes Plus tracks and content from sources other than the iTunes Store, like your audio CDs.
To authorize a computer, follow these steps:
- Open iTunes.
- Choose Store > Authorize This Computer from the menu bar.
You may need to show the menu bar to see this option in Windows. In earlier versions of iTunes, you can access this option from the Advanced menu.
- Enter your Apple ID and click Authorize.
If your Apple ID uses an expired MobileMe account, you can still authorize your computer.
In some cases, iTunes may ask you to authorize the computer again. iTunes should use the same authorization as before if the computer is in your list of authorized computers.
Learn what to do if iTunes repeatedly asks you to authorize when you try to play your content.
Deauthorize a Mac or PC
After you deauthorize, your content will still be on your computer. You may need to reauthorize to play it. You should deauthorize your computer in these cases:
- If you sell or give away your computer
- If you send your computer in for service
- If you reinstall Windows
- If you upgrade your RAM, hard disk, or other system components. If you upgrade these components before you deauthorize your computer, the computer may use multiple authorizations.
If you don’t have your computer and need to deauthorize it, see the steps to deauthorize all computers.
To deauthorize a computer, follow these steps:

Deauthorize all computers
After you authorize two computers, you'll have the option to deauthorize all computers for your Apple ID. You can deauthorize all computers once a year. You should deauthorize all your computers in these cases:
- If a computer doesn't work anymore
- If you don't have one of your computers
- If you used 5 authorizations and want to authorize a new computer
To deauthorize all your computers, follow these steps:
- Click to open your account in iTunes (you may need to sign in with your Apple ID), or follow these steps:
- Open iTunes and click iTunes Store.
- Click Sign In and enter your Apple ID.
- Click your Apple ID and select Account.
- Click Deauthorize All.
The Deauthorize All button appears only if you have more than two authorized computers.
