Ran into a situation where I had to install a new hard drive in my computer. When I went to authorize iTunes, I was told that I had reached my limit of 5 authorizations. I realized that over the past couple of years, I had authorized several computers that I no longer had. Since I couldn’t authorize my new installation, I had to find a way to deauthorize some of the other ones. I found that I could log into the iTunes Store and Deauthorize All my systems and then reauthorize the one’s I’m actively using.
To deauthorize a computer
- Open iTunes.
- Choose Store > Deauthorize Computer (In earlier versions of iTunes, access this option from the Advanced menu).
- Select “Deauthorize Computer for Apple Account” and enter your Apple ID and password.
Make sure you deauthorize your computer before you upgrade your RAM, hard disk or other system components, or reinstall Windows. If you do not deauthorize your computer before you upgrade these components, one computer may use multiple authorizations.
To deauthorize all computers associated with your account
If you find you have reached 5 authorizations, you can reset your authorization count by clicking Deauthorize All in the Account Information screen.
- Click iTunes Store in the menu on the left side of iTunes.
- If you’re not signed in to the store, click the Account button, then enter your account name and password.
- Click the Account button again (your ID appears on the button), enter your password, and then click View Account.
- In the Account Information window, click Deauthorize All.
Note: You may only use this feature once per year. The Deauthorize All button will not appear if you have fewer than 5 authorized computers, or if you have used this option within the last 12 months.
