Hello, I'm new here (so I hope this is the place to post). Lately, I wanted to update some apps, and like in every time I do it, I was requested to sign in with my Apple ID and Password. The strange thing is that it shows me an email which I don't recognize and I can't change it. Someone has an idea? I looked at the System Preferences trying to find out a reason, but I don't find any clue for the strange email on my mac (like in Users & Groups or Security & Privacy). Hacked?
