I bought a new iPad and set everything up using iCloud. I now want to sync videos to my iPad that are on my Mac but every time I try to do this I get the 'This iPad is already sync'd with another computer .Erase and Sync'. This is strange because you can't actually setup and iPad via iTunes any more, only iCloud. So every time I setup and iOS device via iCloud and then try to connect it to my Mac it will always say it's been setup with another computer! Am I losing my mind?
