Cursor is not responding and moving on its own

My battery is not getting hot. MBP: cursor bouncing everywhere! Ran my pinky nail around the right edge of the track pad [my thumb nail is too fat] pressing as hard as I can. then pressed the trackpad four corners at once. problem solved!

I don't know with yours, but resetting the SMC of my RMB worked for me.

Mac notebook computers that have a battery you should not remove include: MacBook Pro (Early 2009) and later, all models of MacBook Air, MacBook (Late 2009), and MacBook (Retina, 12-inch, Early 2015).

To reset the SMC:

1. Shut down the computer.
2. Plug in the MagSafe or USB-C power adapter to a power source and to your computer.
3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
4. Release all the keys and the power button at the same time.
5. Press the power button to turn on the computer.

My cursor started doing the same thing yesterday on my Macbook Pro. Today it went wild and started moving on it's own. I can't get an appointment until Weds at the Genius Bar. I am curious if you found a solution. I have noticed that the battery is getting VERY hot when it is not plugged in.

PROBLEM SOLVED!

Thank the Lord! My mouse cursor was moving erratically, seemed to be opening tabs, maybe doing the equivalent of holding shift and dragging, minimized windows, etc. Pretty much the same problems I see on other's posts.

I tried dissonnecting WI-FI, then shutting off Bluetooth, Disconnected and Turned off my Bluetooth Mouse, disconnected my wireless keyboard nub from the USB port, tried shutting off my Macbook and restrarting. I even shut the lid of my Macbook and worked off my second monitor in clamshell mode. NOTHING WORKED.

I thought I was hacked or had some type of Malware for sure, but it was a simple fix that I found on another help board.

I clean my Mac, keyboard and mouse regularly and had just got done wiping everything with a cloth with a mixture of warm water and rubbing alcohol (recommended)

I saw on another board that someone fixed their problem by moving their trackpad (gently) to the right, since the trackpad seemed to be too snug on the left side of the macbook body edge it sits in.

I moved the trackpad over and it took care of my problem immediately.

It was comforting to learn that Malware on a Mac is in fact still rare and that it is unlikely that someone would hack into your computer to 'remote control' your machine and be obvious about it.

No ghost in the machine. Trackpad is incredibly sensiitive I've learned.

Share the knowledge!

Blessings!

There has also been reports of batteries swelling and causing this type of issue (They are under the track pad)

If the links don't help, bring it to an Apple Genius bar and have it checked out, the diagnosis is free. The swollen battery can cause other more serious issues.

I had this same issue. Turns out my computer was responding to a remote somewhere in my apartment building. I fixed the problem by completely turning off bluetooth and following the directions here:

MacBook, MacBook Pro: Cursor reacts unexpectedly

Your local hardware store should have a #00 Phillips driver. That will allow you to take off the bottom cover of the MBP.

The other option is to make an appointment at an Apple store genius bar and have them examine the battery (for free).

Ciao.

I found out that the problem was solved by turning off the desk lamp with a special tl tube. I suppose that there is a misterious interference between the two devices.

I'm freed of my irritation and happy again.

What do you mean turning off the desk lamp? Mine started last night while my nephew was watching a movie and it started again tonight.

Don't really want to take it to the Genius Bar as they never have appointments when I am free and I don't want to take my MacBook Pro apart.

"I saw on another board that someone fixed their problem by moving their trackpad (gently) to the right, since the trackpad seemed to be too snug on the left side of the macbook body edge it sits in.

Do you mean you opened up the machine and moved the trackpad internally? Or just pushed it to the right from the top?

My cursor was jumping around, opening everything it touched, as if it were pressing on them- it would happen after closing the top and coming back to wake it up. I read this thread and decided to try to move the trackpad very slightly, as I noticed it was closer to one side than another, and depressed on one side. I used a child's snap barrette, the small inner part- a thin flexible piece of flat metal- to go around the trackpad, pulling it slowly and gently away from all sides so that it was even all around. I turned the computer back on and---

So far so good- I've opened and closed the mac several times, been a whole day now- I think it's fixed! thanks, blublud02!

whoa - that is so weird - my daughter was having this problem with her macbook air and I read out your instructions to her on the phone - worked immediately - she was hysterical with laughter that something so peculiar could have sorted it! Thanks a lot!

I've done just about everything and I just finished cleaning my track pad and then I heard something snap inside, But I think it did the trick... it's been a full day and my track pad hasn't gone haywire. Hope it holds out... if it doesn't I'll go to the Apple Store.

I just hope it doesn't cost me. the Warranty just expired and I have no insurance on it.
