My MacBook Pro trackpad is out of control, it's been like this for about a week (doesn't work to restart).

The mouse moves constantly without me moving it, and it's not working probably when it's not moving and clicking on it's own.

The only thing that works (for a short while) is to connect a wireless mouse to my mac, but it's still moving and clicking like it's disturbed or something!

Please help!

    Two common problems are

     

    1) additional pointing devices that are still connected -- the Mac uses "all inputs simultaneously", so the movement you get is the sum of all pointing devices. This is especially diabolical if you have a tablet still attached, as tablet rules are a little different.

     

    2) swollen battery -- this causes pressure under the trackpad and makes it misbehave.

    1) some users complained that their mouse was acting wonky. It turned out they still had their graphics tablet plugged in with the pen sitting on it. "But I was not using that!" answer: "Oh yes, you were, your Mac did not know you were not using that, so it was using both the "Idle" graphics tablet and the active mouse at the same time. When the table shakes, the tablet produced an input as well."

     

    This would also apply to a Bluetooth mouse that was still on, but "I was not using that!"

    In normal use, a properly functioning battery does not swell. A swollen battery is only caused by a defect in the battery.

     

     

    But it is a malfunction that happens often enough that we have heard about it here.
