About two months ago, I had to borrow my husband's laptop, a MacBook. I made an account for myself, took care of business, and returned it. Now, when he logs into his account, it thinks he's me! It wants to update iTunes and three other apps, but it won't let him use his Apple ID. It says that it was purchased by another user. It sends a security thing to his iPhone, but apparently expects mine. (I don't even have 3 of the 4 that want to update.) I have NO idea what happened. Would it help to delete my account? Or would it make it worse? If that's a "no," then how can we fix it?
