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. There is a list of associated devices which can be found in the Account section if iTunes Store.įor more information on Association see this Apple Tech Note (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. By device Apple means an iOS gadget or an authorized computer. You can associate up to 10 devices with each Apple ID. In addition, association allows the use of Apple features such as iTunes Match and Automatic Downloads. More information about Authorization can be found in this Apple Tech Note.Īssociation allows you to download past iTunes purchases onto a different device. However, once a year you can Deauthorize All computers from within your iTunes Store account settings.
Apple only tells you the number that are authorized. If you've forgotten which computers you have authorized in the past, there is not a way to list all authorized computers. You can deauthorize each computer individually. Each Apple ID can authorize a maximum of 5 computers. In order to use apps, audiobooks, books, DRM-protected music, and movies on a computer it must be Authorized. Authorizing a computer allows you to play media purchased from the iTunes Store with a specific Apple ID. I'd like to clarify the terms first, using Apple's own definitions, then answer the question.Īuthorization refers to computers only. But some of the answers here confuse Authorization with Association. The question asks about computer Authorization.
