I just authorized iTunes against a laptop and I was expecting it to be my third of five computers authorized on my iTunes account. But iTunes said it was the fourth.

How do I find out what machines are authorized against my account?

Go to iTunes on a computer and select your Account (on the right hand side of the window towards the top once you are signed in). Select Manage Devices under iTunes in the Cloud. All computers in this list count against the 5 total computer authorizations each Apple ID can have.

Manage Devices

Hmm. That list is completely wrong. It shows two Macs (should be three) -- neither of which are the new Mac I just added. An iPad and two iPhones. I thought iDevices didn't count, it was only computers. So as to where it's getting 4/5 from is still a mystery to me. –  Ian C. Dec 28 '12 at 3:16
Open a ticket with iTunes billing support if the information is outdated or incorrect. They can and should reset things if your account doesn't match what iTunes lists. The once a year reset does complicate things since some older computers could be authorized against the "last 5 slots" and not the "current 5 slots". –  bmike Dec 28 '12 at 3:40
My list is empty. But apparently I have authorized five devices already since Home Sharing cannot be activated on my Mac. –  gentmatt Dec 28 '12 at 10:43
@bmike so Apple just reset all the authorized devices on my account for me and had me re-authorize the three Macs. I get the right "out of 5" count now but the list of devices under 'Manage Devices' only shows my iDevices, no Macs, now. Go figure. –  Ian C. Dec 28 '12 at 17:05
@IanC. What you describe matches my experience with a reset. Any computers and devices continue to work and cen re-auorize yet no longer show or enumerate on a list of user machines. –  bmike Dec 31 '12 at 20:11

The question asks about computer Authorization. But some of the answers here confuse Authorization with Association. I'd like to clarify the terms first, using Apple's own definitions, then answer the question.


Authorization refers to computers only. Authorizing a computer allows you to play media purchased from the iTunes Store with a specific Apple ID. In order to use apps, audiobooks, books, DRM-protected music, and movies on a computer it must be Authorized. Each Apple ID can authorize a maximum of 5 computers.

You can deauthorize each computer individually. If you've forgotten which computers you have authorized in the past, there is not a way to list all authorized computers. Apple only tells you the number that are authorized. However, once a year you can Deauthorize All computers from within your iTunes Store account settings.

More information about Authorization can be found in this Apple Tech Note.


Association allows you to download past iTunes purchases onto a different device. Apple calls this iTunes in the Cloud. In addition, association allows the use of Apple features such as iTunes Match and Automatic Downloads.

You can associate up to 10 devices with each Apple ID. By device Apple means an iOS gadget or an authorized computer. (Since every associated computer must also be authorized that limits you to 5 associated computers for these features.) So you can associate one computer and 9 other devices, or 5 computers and 5 other devices, but not 9 computers and 1 other device. You're limited to 5 computers.

There is a list of associated devices which can be found in the Account section if iTunes Store.

For more information on Association see this Apple Tech Note

So the only way to determine which computers are authorized is by trial and error: Deauthorize each computer you own in turn using Store > Deauthorize This Computer… within iTunes.

If after doing this the iTunes Store still says you have authorized computers, you only have one option: Use the Deauthorize All feature of iTunes Store, and then reauthorize the computers you own. But keep in mind, Apple only allows you to Deauthorize All once every twelve months.

It looks like there is no way to see which specific computers are authorized; you can only see how many are authorized.

Per this Apple discussion thread, you will have to deauthorize all of them and reauthorize only the ones you want to be able to play.


I'm not sure if devices count toward this limit.
