Jumpy erratic cursor/arrow - Moves & Selects without touching

I've been having the same problem on a daily basis lately. I tried making my MacBook Pro go to sleep, restart it, shut it down till it cool down then turning it on again, but nothing worked! I cleaned the trackpad vigorously and thoroughly several times, still nothing. I just read about SMC resetting (am I saying it right?) and I tried it but it didn't work at first. Eventually I removed the pink plastic case I've been using for two years, cleaned my MacBook up (there was soooo much dust and dirt collected underneath that case) and voila! I have now an obedient trackpad. So I'm not sure whether it's the SMC thing or removing the plastic case. Either way, you should try both. Good luck!

How much does it cost to replace a trackpad, if I may ask?

If the surroundings are not clean it is not conducive to the efficient operation of anything electronic. A dirty (I don't say that rudely) environment leads to unclean air and in which grease breeds with all the problems that can bring.

You don't have to be immaculate, you do have to be aware. This is not an issue that Apple can address; only you can, the user.

Came to just over $100.

Ouch!

I had this problem, but when I disconnected my monitor and reconnected it, the problem went away.

Saw the solution in another thread and worked for me … My pointer was moving to the right on its own and opening stuff, and it was impossible to move it to the upper left corner. Press the pad slightly and move it to the right. Seems it must have gotten out of alignment.

I have a MacBook Pro 15" 2002

I tried what you suggest and it seemed to fix my problem, for ten minutes, then the cursor began acting erratic again. Weird thing is, prior to trying this I took my Macbook to the Mac store in NY, and they made me run a few tests, including one specifically for the trackpad where I had to touch each part of the trackpad and get a verification that everything was working fine. During the test, the centre of my trackpad, almost a horizontal line of area, was concluded to be not working and I was adviced to change my trackpad. I came back home to mull over it, tried your method and it worked, well at least briefly.

I wonder what the problem is, and how doing the 'disk first aid' fixes it, even if only for ten minutes, and if this is actually a hardware problem if there seems to be some sort of temporary fix.

Pressing all the corners worked for me, at long last. I also slowed my tracking speed. Don't know if this is definitive or temporary, but thanks.

PS Using a late-2009 MacBook Pro running Yosemite, 10.10.2.

I was having erratic cursor issues in my MacBook pro 2011 10.6.8

From time to time it was stabilized but becoming more and more apparent I had to find a fix.

The looming option where I live is to bring it to an authorized apple service center, or a guy good with Macs.

I tried disk utilities and repair disk permissions, everything was fine.

I cleaned the trackpad,which seemed to work only twice.

I the decided it was time to upgrade to Yosemite, which made the situation worse. It started to go between windows.

So before I brought MB in to be looked at. I decided I was going to go through this enduring process to delete my Safari history, which I proudly say are my dirty movie sites.

My primary browser, Firefox does not have these sites on it.

This is what fixed my issue!!! Deleting my Safari history.

I am so happy,I am writing this simple thing that worked for me.

I literally was going to delete,shut down,and bring it in for whatever they would say.

I hope this helps.

I have this issue as well on a Retina Macbook Pro 15-inch from 2014. I reset the SMC controller by pressing left shift + control + option + power button when the computer is turned off. This has fixed the issue for me. Not sure if it will last though. If it gets jumpy and weird all over again, I might have a defective trackpad that needs replacement.

I've been tearing my hair out about this issue and then i found this:

It worked a treat for me.

I am been having the same problem. This helped me fixed it! Thank you!

UPDATE, UPDATE, UPDATE.

This fixed my daughters MacBook touchpad issue.

Solved this problem by reading more help on Google.....I got a Qtip and cleaned the little blue sensor...and like magic, it works!
