Q: Magic Trackpad has a mind of it's own!

My trackpad seems to have a mind of it's own.  When I move the cursor around the screen, the trackpad selects as though it is being pressed.  When I open a pull-down window, the trackpad selects items without being pressed.  I've bumped the PRAM and accomplished an SMC reset.  Niether action has had an effect.  Has anyone else had this issue?  How did you clear it up?

Magic Trackpad, OS X Mountain Lion (10.8.2)

    This worked!

     

    Here's my story .... I just had an update on Yosemite to 10.10.2 last night. Worked fine this morning ... not until the evening did it start to act up. Read various threads ... tried a few things ... but popping out the rubber feet did the trick. Problem went away. My MTP was going crazy ... selecting everything. At one point, I left the mouse right over the Apple on the top left corner of my iMac and watched it select the Apple as if I was going to shut it down numerous times. Then, after popping out BOTH of the rubber feet, I swapped each (right to left and vice versa) ... I also blew some air inside where I propped open the MTP to pull the rubber feet out just in case something was lodged in there. Bottom line, I re-assembled it, and BAM! ... While typing this, my MTP is behaving. Not making any selections randomly.

     

    I would suggest you Google "iFixIt for Magic Trackpad Rubber Replacement/Reinsertion" to get instructions on how to take those rubber feet out. I popped open both corners, pulled out the feet, cleaned them (just in case), blew air in the area where they were installed, swapped them, popped it back together. Done deal!

    I have a 13" MBP from mid 2010. Its trackpad is randomly erratic. Reading the 59 answers gave me the unlikely idea of lack of grounding.

     

    It works!

     

    Fingers on the trackpad brings erratic behaviour. Thumb of the other hand on the chassis outside of the trackpad and the mouse becomes 100% responsive.

     

    Mystifying as ****.

    Made me laugh, reminded me of the GOOD old days with TV rabbit ears. Okay hold left antennae with right hand, lift right leg, freeze don't move show will be over in 30 minutes Just should not have to go through this. I had problem with my previous desktop. When I replaced that with a late 2013 27" that came with another trackpad it worked fine, still does months later. Never tried old track pad with it so don't know if was that or computer but leads me to believe one way or the other was a HARDWARE issue since this one works fine running same OS.
