My trackpad seems to be malfunctioning. The cursor jumps around and doesn't always respond. The screen shifts from one to another involuntarily. Does anyone have an answer to this problem?

Portables and Magic Trackpad: Jumpy or erratic trackpad operation
Does this occur with the power adapter connected, disconnected, or both?
Check your battery status. A battery that reaches its end of life may swell, creating pressure beneath the trackpad that will result in the symptoms you describe.

Is anyone having trouble with the cursor jumping around since Lion was installed on your computer? Never happened until Lion.

Is anyone having trouble with the cursor jumping around while typing since you installed Lion? Never had any problems of that sort prior to Lion. I have an older machine. I believe it is a 2008 MacBook Pro. Especially happens with Yahoo. I am baffled.

Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

On my Macbook Pro my cursor jumps around and does it's own thing even with a usb mouse, on my Macbook Pro my cursor jumps around and does it's own thing even with a usb mouse

Having trouble with my MacBook Pro and the cursor jumping around and doing it's own thing. Clicking opening up other folders etc.

There are several possible causes for this issue. Take each of the following steps until it's resolved.
1. Follow the instructions in this support article.
2. Boot in safe mode and test, preferably without launching any third-party applications. If you don't have the problem in safe mode, but it comes back when you reboot as usual, stop here and post your results. If you can't boot in safe mode, do the same. If you booted in safe mode and there was no change, go on to the next step.
3. Reset the System Management Controller.
4. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.
5. A swollen battery in a MacBook Pro or Air can impinge on the trackpad from below and cause erratic behavior. If you have trouble clicking the trackpad, this is likely the reason. The battery must be replaced.
6. There's a report that a (possibly defective) Thunderbolt Ethernet adapter can cause the built in trackpad of a MacBook to behave erratically. If you're using such an adapter, disconnect it and test.
7. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
8. If none of the above applies, or if you have another reason to think your computer is being remotely controlled, remove it from the network by turning off Wi-Fi (or your Wi-Fi access point), disconnecting from a Bluetooth network link, and unplugging the Ethernet cable or USB modem, whichever is applicable. If the cursor movements stop at once, you should suspect an intrusion.
9. Make a "Genius" appointment at an Apple Store to have the machine tested.

T420 problem: Cursor jumping around

Hello everyone, I have a new T420s. Whenever I type a text the cursor jumps around which is very annoying. I have already deactivated the touchpad but the problem persists. What can I do to solve it?
Many thanks,
Torsten

You can turn the trackpoint (stick) off on the T420, it does not seem to allow you to turn the trackpoint and touchpad off at the same time through the UltraNav utility, but it might be possible in the BIOS.

Track pad cursor jumping around without being touched

My daughter has a macbook pro 1.5 years old running OS 10.6.8 and for the last two weeks has had the cursor jumping around and clicking on anything and everything. She is in college and uses airport to connect to college network. What is the problem?

You have some type of hardware problem. More then likely the battery is swelling and putting presure on the trackpad. The only thing to do is take to Apple and have them check it all out, replacing any parts that are needed.

Email cursor jumping around while typing????

My cursor jumps around while I am typing and is just erratic.

I have this issue as well. I am using a early 2008 macbook, 2.4ghz intel core 2 duo. I usually am only typing on this computer for email. I have tried both firefox and safari with the same issue. I was initially hoping it was just a bug in the application, but that doesn't seem to be the case.

Iphone 3gS Cursor jumps around.

My Iphone 3gS cursor jumps around on occasion when typing texts or emails. The issue has persisted despite several resets and software upgrades. When the cursor jumps, it can either go to the next line or else into the "Sent from my Iphone" line. Any ideas on the cause and especially on how to fix this? Thanks in advance!

I "catch" this ... I can only call it malware / miscellious software... occassionaly when browsing not always legit sites on the deep web.
Here's how I'm able to sucessfully clear that condition.
Power down the notebook
Reset the SMC using the power adapter to verify the SMC reset.
Immediatly after resetting the SMC reset the PRAM several times 3 or 4 times.
Allow the Mac to boot normally.. No more issue.

My cursor jumps around while typing and scrolling. i've tried different mice, different usb ports

I have a new HP pavillon HPE windows 7. My cursor jumps around while typing and scrolling. I've tried different mice and usb ports.I contacted HP support and was instructed to do several things to the mouse and pointer, nothing helps. I installed in usb port in the rear of the computer that helped for a short time, then it went back to jumping around. So what else can I try. Thanks

I have to admit I am baffled. I understand and have seen the issue happen on laptops before, but for the issue to be happening on a desktop strange. I can even understand a wireless mouse, however yours is wired.
Microsoft has a tool called Mr Fix it. It scans the problem area and attempts to fix whatever is wrong. It's worth the shot in this case to see if it helps resolve the mouse issue.

HT203171 Why is my cursor jumping around?

THe cursor on my Macbook Pro has suddenly started jumping around even when I am touching nothing. It seems to have started after I installed a free Photoshop trial. I have done a Safe Start but nothing has changed.

There are several possible causes for this issue. Please take each of the following steps that you haven't already tried until it's resolved. Some may not apply in your case.
1. Follow the instructions in this support article, and also this one, if applicable. A damaged or defective AC adapter could be the cause, even if it's the right kind.
2. Press down all four corners of the trackpad at once and release. If there's any effect, it's likely to be temporary, and in that case the unit must be serviced or replaced.
3. Open the Bluetooth preference pane in System Preferences and delete all pointing devices other than the trackpad, if applicable. Disconnect any USB pointing devices. By a "pointing device," I mean a peripheral that moves the cursor, such as a trackpad, mouse, trackball, or graphics tablet. A plain keyboard is not a pointing device.
4. Start up in safe mode and test, preferably without launching any third-party applications. If you don't have the problem in safe mode, but it comes back when you restart as usual, stop here and post your results. Do the same if you can't start in safe mode. If there was no difference in safe mode, go on to the next step.
5. Reset the System Management Controller.
6. If you're using a Bluetooth trackpad or mouse, investigate potential sources of interference, including USB 3 devices.
7. A swollen battery in a portable computer can impinge on the trackpad from below and cause erratic behavior. If you have trouble clicking the trackpad, this is likely the reason. The battery must be replaced without delay.
8. There's a report that a (possibly defective) Thunderbolt Ethernet adapter can cause the built-in trackpad of a MacBook to behave erratically. If you're using such an adapter, disconnect it and test.
9. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
10. If none of the above applies, or if you have another reason to think that your computer is being remotely controlled, remove it from the network by turning off Wi-Fi (or your Wi-Fi access point), disconnecting from a Bluetooth network link, and unplugging the Ethernet cable or USB modem, whichever is applicable. If the cursor movements stop at once, you should suspect an intrusion.
11. Make a "Genius" appointment at an Apple Store to have the machine and/or external trackpad tested.

Mouse cursor jumping around

My cursor on my MacBook Pro at times jumps around and the screen size changes without warning. Also, the screen will jump from safari to desktop without warning. I have changed settings in system preferences back to the most basic settings and this has seemed to solve some problems.

I had a similar problem with a wired mighty mouse at a former job, and a current co-worker is having this happen with her wired mighty mouse as well.

Cursor Jumping around forms as type - now with 3.6.12 on windows 7 - makes impossible to use

Have windows 7 installed with Firefox 3.6.12 - whenever bring up page with multiple field entries - as I type it jumps all around the page into other text areas or around inside the same text area and even seems to activate some navigation and submission options when I do not want it to.

I am also having this problem as well. When i try to click on the web search box (to type in a web address), also anything i click on or try to type is jumps around all by it's self.(It's the mouse cursor) When i even point or try to click it goes all over the place i get dizzy watching it dance all over the place! I have never had this problem before EVER! I though something was wrong with my computer and i decided to google it and see if anyone else is having any trouble with this, and i found that several people are. I thought maybe it was because i haven't updated to a newer version, so i did that and it didn't correct te problem at all! any helpful suggestion will be greatly appreciated! I also don't see how i will correct the problem if it is jumping all over the place no matter what i do. Also, I do not have any other things open or running on my computer to cause any problems.

Cursor jumping around on curve 9300

Hi, I've seen many people posting about this problem, but have yet to see a solution. The cursor on my Curve 9300 jumps around all over the place.
- The problem started before I did a software update.
- It is not from track pad over-sensitivity. I've used the device for several months without problems. I did change the sensitivity, just in case. The problem persists.
- I've pulled the battery several times, no effect.
- I upgraded the software version 6 bundle 2647, no effect.
- I've seen that some people have this problem when using the device in direct sunlight. Not relevant here - happens indoors or outdoors, and I am seldom if ever in direct sunlight (sadly).
If anyone could help me with this, I'd be most appreciative. Thanks.

yes if it is still under warranty sorry but seems there's nothing else we can do. i kept patient on using it for months while trying finding any possible soft repair but i get nothing
it is not that happy to hear that we can have new device since it comes with new PIN which means we lost all data.
good luck on yours

Cursor jumps around the screen

After upgrading to Lion, moving my mouse will intermitently jump the cursor from it position in the middle of the screen to one of the edges.
I will try to move the cursor an inch or so in the middle of the screen and find the cursor hitting one of the hot corners, which is really annoying when I go from clicking a toolbar item in the center of the screen to a sleeping display.
The mouse is a Magic Mouse, wtih a MacPro. It worked fine with 10.6, but is annoying enough under Lion to make me want to ditch the mouse and try a track pad.
Anyone else seen this one?
Thanks.

I have a 2011 MacBook Pro (bought it in August). I have it hooked up to a 21-inch monitor and a wired Mac extended keyboard. I have a wireless Magic Trackpad, a wireless Magic Mouse, an old wireless Mac Mouse, and an old WIRED Mac Mouse. (Note that I haven't been using them all at the same time, I turn each off if they are not in use).
My pointer jumps around when I use each one. Given that the same jumpiness is occurring when I use my wired mouse, this would indicate that it is not a Bluetooth issue a...although my old wireless Mac Mouse is by far the worst performing of the four.
I submitted my feedback to Apple in August, no replies. What a joke!

My trackpad seems to be malfunctioning. Cursor jumps around. Screens shift.
