My cursor moves on it's own and does not respond to my movement on the trackpad or a USB mouse.

Blublud02,

thank you for your advice. My cursor went crazy and I realized it was after I cleaned it. So I gently pressed from the left side to the right side of the pad and my cursor is obeying me again. Thanks

Hey! I have the same problem. My cursor works fine in safe boot, but when I reboot it normally its crazy again...what is the problem?

Simple, effective, brilliant! I just gently pressed from the left to the right side of the trackpad, heard a very very subtle click noise… and it's now smoothly working again! Thank you so much!!!! 🙂🙂🙂

Same happened to me, I also thought is was a virus, but after reading this, I remembered that right before the problem started I was cleaning the trackpad and made a little force to the left to clean a stain on it.

I pressed the trackpad gently back to the right and symptoms disappeared.

Thanks

This is really an annoying and irritating problem. The problem with the trackpad started after my little one spilled some water on the trackpad. I tried to clean the tracked pad and may be I applied a bit of force to clean the trackpad. Within few minutes the track pad started acting mad. I did all sort of things to bring the cursor back to normal, including cleaning, reset by disconnecting battery, safe mode boot, etc. etc. but nothing solved the problem permanently until I took a credit card and pressed the track pad from top to bottom and let to right.

Thank you so much for this suggestion Blublud02.

My cursor was going through the exact problem until I cleaned it with an alcohol pad and pressed the trackpad a gently bit to the right and now IT'S WORKING fine. Didn't know how delicate these MacBooks were, but I appreciate your advise. 🙂

This happened with my husband's 2011 MacBook Pro. It seems as if the trackpad button in stuck in the "down" position and it kept making selections on the screen. He uses a USB mouse and rarely uses the track pad, so I made the change in the Accessibility preference to disable the trackpad when a USB mouse is plugged in. It works fine with a mouse, but the trackpad is still stuck.

THANK YOU!!! After all the waiting, cleaning, rebooting, buying new mouse, your advise WORKED with a credit card. My friend tells me that now the magnetic band of my credit card won't work LOL. Thanks again.

My cursor is getting like a horse

My husband has been complaining about his trackpad causing him problems. The mouse just taking off across the screen and clicking things on its own. After I read your response, I took a look at it. I could see that the trackpad on his laptop was off kilter. It was slightly turned. My guess is part of it was under the bezel and the OS thought it was being touched. I just used my hands and straightened back up. Voila! Works like new again. Thank you, thank you!
