Ok, I have never touched a Mac or an Apple. However, my mother, who is 83 and nuts just bought a new Ipad Air 2. BTW, I am a technology coordinator for a large organization, so I am familiar with computers. So, she tries to set it up, having no idea what an Apple ID is, and somehow, she set it up with an email that is totally wrong, non existent. So, now I have to learn all about these things. My first problem that I need to resolve is to delete that bad email address, which shows up in the iCloud part of settings. I tried to reset to factory settings, but, I do not know the password. Any help or ideas appreciated.
