iTunes on the Mac

If you've recently started using a new computer and tried to start using iTunes, but were thwarted by the dreaded "Cannot authorize this computer" message, fear not. There is hope!

We've all been there. Get a new device and can't authorize it with iTunes, so you can't enjoy any of your previously purchased content. The most common problem with not being able to authorize a computer is that you have too many of them already authorized. Due to licensing agreements, you can only have a maximum of five computers authorized under your iTunes account at the same time. You may have old computers that you never deauthorized, or a work computer that you previously used to listen to your finely crafted playlists.

If you know you have five computers, and want to add a sixth, well - you're out of luck. But, if you are currently only using two or three computers to play your iTunes music, you can remove old ones to make room for the new.

Before making any changes to your computer or the iTunes app, be sure to back up your iTunes music library (we can't stress this enough - seriously, back it up).

If you have no idea how many computers you have authorized to access your iTunes account, you can find out in your account settings.
