Macbook Pro cursor jumping around

My cursor for my macbook pro is jumping around? anything I can do to fix it?

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. Open the Bluetooth preference pane in System Preferences and check for unknown or forgotten input devices. Disconnect any USB input devices that you aren't using.
3. 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.
4. Reset the System Management Controller.
5. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.
6. 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 without delay.
7. 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.
8. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
9. 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.
10. Make a "Genius" appointment at an Apple Store to have the machine and/or external trackpad tested.

2011 MacBook Pro Trackpad jumping around

Ever since last night the trackpad on my mid-2011 15" MacBook Pro hasn't been working. The cursor keeps jumping all over the place and I can't really get the trackpad to respond to my touches. I can eventually get it where I need it to move but it takes a lot of effort.
I've tried resetting the SMC and PRAM/NVRAM but that doesn't really do anything. It helped once at first but quickly went back.
Any other suggestions as to what the problem is?

I think you might be right about the swollen battery. I'm aware of the stuff in the article that Kevin linked to. I know that having wet fingers can lead it to do that and it's not like my hands would have been wet for 24 hours anyway. And I'm using a standard Apple three pronged grounded power adapter, so not a problem with using an aftermarket one.
I'm pretty sure that it is related to either the battery or power somehow though, because after disconnecting it from power and trying to use it for about 45 minutes, the problem went away. Worked pretty normal as I was using it for the rest of the time but the issue came back shortly after re-connecting it to power to charge the battery again.
Unfortunately I can't take it to an Apple Store to have it checked out though because I'm in a remote location for work for the next 3 weeks.

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.

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.

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.

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.

I have an aluminium Macbook Pro 15" from around 2009 currently running 10.5.8. Apparently I need to be on 10.7.2 to get into iCloud. System Profiler says my machine is Core Duo, but also says it has 2 cores - can I run 10.7.2 on this machine?

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

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.

Retina Macbook Pro randomly jumps to logon screen without warning

My Retina Macbook Pro randomly jumps to the logon screen while I am using it. When I log back in some programs have stopped running and any unsaved work has gone. It has happened while I am not typing or touching the keyboard or mouse as well.

I have the exact same problem with my Retina MBP. At first I thought it was occurring when I CMD+Tab-ed between apps but I've had it jump to the login screen without even toughing the computer. Very frustrating. Upon login I have to wait for apps to reload and I lose unsaved changes. Anyone have any advice?

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.

When typing (either email or word document), the cursor jumps around, inserting characters randomly. This has been a problem since I received the computer. The issue seems to be resolved if I disable the touchpad.

Please try reinstall the touchpad driver. or try the latest touchpad driver from hp.com which can help fix the issue.
