Trackpad Spazz

Yes. Same symptoms. Mouse spazzes out too.

I have noticed that battery life indicator is different from snow leopard os than lion.

If fresh batteries or good battery life shown in lion, then restart in snow leopard, tells me batteries are going bad. Would think restarting to an old os would not be a good solution to determine accurate battery life though.

I also have seen that weird error log thing on starup which i did want to blame on the trackpad.

had the same problem this morning. it just started randomly. after adjusting a million settings, i called apple and they worked on my prob for about 20 mins. not sure what exactly stopped it, but i have a feeling i may have been being hacked. i told the rep that it looked like a ghost was controlling my trackpad...opening apps and cursor was all over the place. to my dismay, i had screen sharing on. if you tried all of the above (cleaning, no bluetooth devices) turn off screen sharing. thanks apple!

I am now having the same or similar issues, frustrting, I am wondering if my issue is due to Mavericks? the batteries only last a week or two now, it intermitantly selects and hilites anything it passes, I change the (rechargeable) batteris, wiped the trackpad, double checked its settings/ preferances, still an issue at times, could the thing be defective or mavericks? what else

I find the spazz happens often independent of the input device used. happens more often when multiple browser tabs are open.

I get the problem using a trackball, wireless magic mouse, and the trackpad.

I find hitting the esc key while moving the ball or mouse around wildy helps restore the cursor.

I believe the issue is more prevelent in lion and up. I was running an old backup drive of Snow Leopard a few weeks back and could not replicate the error with about every application running at full steam. So think I could eliminate low Ram as a cause.

My trackpad has lost its magic too. It is making me insane. It jumps all over the place. Scrolls erratically. I have tried every solution so far. I would love a fix for sure.
