I have a 20" Intel Mac running the latest OS. I am experiencing a jumping cursor in all text editing applications. I have changed from wireless key board and mouse with no change. Apple Care has not solved the problem.
I get this problem sometimes, but not very serious. I just searched for it because I was curious. I'm using a mid 2009 MBP touchpad.
Seeing how both touchpads and mice get it, it looks like a software problem. Maybe some conflict.
On my Windows laptop, sometimes the touchpad would become unresponsive. I think this is due to accumulated static. I swipe the whole touchpad with a finger (like wiping dust off it) and that helps.
How do you reset the display?
I have been having the same issues on my MacBook... cursor seems to have a mind of it's own. Jumps around while typing, highlights, deletes, selects things without my fingers anywhere near the trackpad. Very frustrating!!
After searching many forums and looking it up, I may have an answer for some.
Btw- for me it had nothing to do with my mouse, or accidentally touching the trackpad. Also reset PRAM a few times. And trackpad was clean.
TRY THIS:
In System Preferences, under Trackpad, not only selected "Ignore accidental trackpad input", ALSO selected "Ignore trackpad when mouse is present".
It has worked for me for 5 days now, when this issue occured daily.
This leads me to believe there is a definite issue with the trackpad. Just read the previous post about the battery which certainly could be the issue here.
Hope this relieves some of your cursor anguish!

Just came across the same problem with my MBP. The problem was not a battery issue or a setting in preferences. Turns out that there was an issue with the hardware on either side of the trackpad that when pressure is put on it, as slight as resting my wrists on the computer it would cause the cursor to jump around. I am getting this fixed this week, but if you are still having this problem on your MBPs try typing and pressing around on a few spots. On mine it seems to happen most often at the top/left of the track pad. Hope this helps.
I feel very sure it's a virus. Someone (or something -- a bot of some sort) is trying to take control remotely of my cursor. Whoever suggested that is right-on...
Hey Kimberly,
it seems we were typing at the same time. I'll try what you suggest..; Fingers crossed!!
Well, I did it all!
Run MacScan, no virus found.
Asked the Facebook support team.... they gave me a totally fishy answer
Then did what Kimberly explained, all seems to be fine. But most importantly now that I removed the battery I can see that the trackpad and its clickable area (don't know what it is called!) works much better. So I think it was a hardware problem, with the battery sort of pressing the trackpad up.
Following Kimberly's instructions above, I waited for the second chime and released the keys at that point. I was then greeted with a folder icon containing a question mark center screen. Waiting the longest time without touching any keys, I eventually couldn't stand it any more and rebooted. When I tried again I released them after the first chime. Success!As soon as you turn on the computer make sure you hold down these 4 keys all at the same time. COMMAND, OPTION, P, R
Yep, it resets the NVRAM (Non Volatile RAM) and it works!Apparently it resets something.
