    I am experimenting with mirroring my Macbook Pro Retina (2012) with my new AppleTV.

    The mouse keeps jumping to the top-left area of the screen, no matter what I do. I don't have anything running - just the MBP with Airplay mirroring.

    any ideas?

    airplay mirroring shouldn't touch your cursor.

    are you using a mouse? or the builtin trackpad?

    I'm using the trackpad, but nothing's touching it.

    Is your battery swelling? I had a similar problem a couple of years ago and it turned out that the battery was swelling just enough to put pressure on the underside of the trackpad causing the curser to jump around.

    I would take the battery out and inspect it. You could then plug your computer in to AC power without the battery as a test.

    Oddly my battery is again swelling but this time the trackpad is behaving but my cooling fan is making a buzzing sound.

    It's not swelling.

    After some substantial testing (and googling) i'm sure that this is a bug with mirroring. I ended up using just an AppleTV and mirroring to one screen, since I could not find a reliable solution for two screens.

    I almost got it working with my MBP, AppleTV, and Splashtop...but even besides the mouse issue, you could see the mac struggling to decide on a screen resolution between the three displays.
