This used to be easy. I too had many old devices hanging around. I and running Mac OS 14.4.1 on iMac M1 2021 and on MacBook Air M3, new iPhone 14 with iOS 17.4.1 an Apple TV and an Apple Watch OS 10.3.1 . I will say the phone upgrade went remarkable well even though have my devices connected so they can unlock each other. Thankfully the guy at the AT&T store knew his stuff and we got through it. However the issue became computer authorizations like this thread discusses. In the old days of iTunes it was pretty easy to authorize and deauthorize computers. I am not sure why it is so difficult now. It was my MacBook Air where the problem surfaced. I was trying to open a book in iBooks and of course it wasn't authorized and I was above my limit. Getting to the authorization management wasn't intuitive. Here is what I did (and even if you have no books, I believe the app will behave the same way. ) I did this from my iMac .
- Open Books
- From the Account meant on the title bar , select View my Account
- Scroll down and select View Account Settings
- On the next dialog box, Select View Account Settings
- It will prompt you to Open the App Store. Click OK
- This will take you to a slightly different page than you would get if you opened Account Settings from with in the App Store app if you opened that directly,
- You get a single choice here to Deauthorize all. You don't get the old list of authorized computers. I don't own some of those anymore. So I chose Deauthorize All
- At that point I could go into all my computers that still have and click on the "Authorize the Computer" It worked great and I am back in business.
