Hi, A window was opened on my mac book pro when I came back to it from an hour idle and a strange window was open that I've never seen before. It was a pairing request from T-Mobile with a number in black and it asked me if the number corresponded with something. I said no and it went away, but now I'm a little caught off guard by it and worried. And that would be because I don't have TMobile nor do I have Blutooth. Any ideas?
