Topic : Authorizing computers

Individual computers can only be deauthorised directly on them, but if you have 2 or more computers authorised (you can have a maximum of 5) then you can log into your account on your computer's iTunes (Store > View My Account) and 'deauthorise all' (which you can do once every 12 months) and you can then authorise/reauthorise the computers that you still have and need : authorising and deauthorising.

No, it doesn't remove any content, it just means that you won't be able to use iTunes downloads on those computers until you reauthorise them.

The instructions here don't work as of May 2015.

You have to:

1.Go into ITunes and look way up in the top left corner for the little black and white rectangle

2.Click on the rectangle.

3.Click on Itunes Store

4. Click on Authorize or Deauthorize this computer

Nothing else worked from all the suggestions on all the websites.

Totally user unfriendly! :-(
