Not enough storage space to update iPad mini I don't have enough storage space to update my iPad mini  from iOS 7 to iOS 9. As advised I have linked to MacBook Pro through Bluetooth but cannot see what the next step should be. I have little IT knowledge so answers need to be idiot proof.
Since iOS 9 is smaller in file size than iOS 7, you can just delete a few songs or podcasts or apps, whatever is taking up space, then install iOS 9, then re-download whatever you deleted. This can be a bit faster than restoring from backup, although it is still a good idea to back up your iPad!
