How to de-authorise missing computer?
I can’t sync my apps on the iPhone, in iTunes it tells me to go to store and authorise it and this is the reply I get
This computer is already authorized. Including this one, you have authorised 4 computers out of your available 5.
I have a Mac, an iPhone, and an Apple tv 4, all authorised to upload apps etc so that explains 3 the other one could be an old mac or iPhone please advise how to just have the 3 authorisations. Thanks
iMac, OS X El Capitan (10.11), aim chat (viv0147)
