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-OTHER, OS X Mountain Lion (10.8.2)
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.

Thank you so much I didn't see how this would help but tried everything else and as soon as I moved the two folder it started to work perfectly thanks a lot
If all else fails, make sure your Macbook has adequate power. I have noticed that when my battery is lower than about 20%, the trackpad isn't as clicky or responsive as it should be, and it often acts like I'm clicking on things or highlighting text when I'm not. I plug in, and the issue is immediately solved 🙂
