Mouse pointer jumping around screen!

hey guys, iv had my iMac for around a year now and only recently iv noticed that the mouse pointer just jumps randomly across the screen when i move it, like ill be moving the mouse to the right and itll jump across half the screen to the left.
It happens at least once an hour or something like that and only seems to happen when im move the mouse quite quickly. im using a laser wired mighty mouse that come with my 20" iMac which is around a year old, thanks.

Hello again Beanie_,
Is yours, the iMac, the 2.4Ghz version? My own iMac does this " trick " every now and then. There are several threads about the issue here in Apple Discussions and a veritable mountain of information inside Google.
Regards once more and now, I trust, you will see why I asked my 1st question!
Ian.

Mouse pointer jumps around screen

My Emac mouse pointer jumps aroung the screen. I have tried restarting and a permissions repair. I'm still having the problem. Any ideas?
Emac Mac OS X (10.3.9)

Is this the original Apple mouse? Do you have any third-party mouse drivers installed? (Look in System Preferences under "Other"). Presumablly you've tried adjusting the mouse sensitivity in System Preferences; have you also checked if the mouse if jumpy in other user accounts? If you can, try a different USB mouse on the eMac to ccheck it's not the hardware.
You can test if the mousing surface is at fault by using a plain sheet of heavyweight bond paper as a mouse pad. If that resolves the issue, try the tip first suggested in the eMac Discussions by Ron Jackle: use a plain floor tile as a mouse pad. You want one that's non-glossy, fairly plain, and not too refelctive. I've got such tiles in use on several computers (Macs, PCs, and Unix), using a light tan 8x10 tile from Home Depot, label 8x10-5202, SKU 3057645425, which retails for about US$1 (I recall the last one beint 89 cents plus tax) when bought one at a time.

Mouse pointer jumping around the screen

My mouse pointer has just started jumping around the screen. It vibrates and slowly moves down the screen even if I am not touching it. I have cleaned the sensor but that has not helped. I unplugged it and the pointer still jumped around.
Any ideas what might be causing this as I have not seen quite this problem on other discussions.

HI,
That's interesting... restart your iMac. See if that makes a difference.
Also, do you have anything nearby that might cause interference, like a cell phone or graphics tablet?
May sound crazy, but dust and lint build up on a mouse pad can cause erratic cursor behavior.
You could try deleting this file.
com.apple.driver.AppleHIDMouse.plist
/Users/YourName/Library/Preferences. Drag that file to the Trash, empty the Trash and restart your iMac.

Mouse pointer jumping around since 10.10.3

Dear all.
Since 10.10.3 upgrade my mouse pointer is jumping around all over the place.
First i thought it was maybe a bluetooth issue (i am using magic mouse) so i disabled that.
But.. without active magic mouse, the mouse pointer still keeps jumping.
So now my macbookpro has become almost unworkable.
Anyone ?

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 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. If your model has an infrared receiver for use with an Apple Remote, disable it.
5. 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.
6. Reset the System Management Controller.
7. If you're using a Bluetooth trackpad or mouse, investigate potential sources of interference, including USB 3 devices.
8. 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.
9. A defective peripheral device or a damaged cable can cause the built-in trackpad of a MacBook to behave erratically. If you're using any wired peripherals, disconnect them one at a time and test.
10. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
11. 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.
12. Make a "Genius" appointment at an Apple Store to have the machine and/or external trackpad tested.

Mouse Pointer Jumps to Screen Corners

Greetings,
I have been having this problem since I got my G5 a month ago. Some times I'll be moving the mouse and all of a sudden the pointer on the screen will jump to either the top right corner or bottom left corner of the screen even though I'm no where near those areas. I am using the mighty mouse and keyboard that came with the computer.
Can anyone tell me why this is happening? It's very annoying.
Also, sometimes the pointer will change to that rainbow animated circle and I won't be able to use the computer for a couple of seconds. Does anyone know what that might be as well?
Thanks in advance,
Russ

Mouse jumping to corners is usually a reflection problem with the laser, use a different pad/whatever. Clean the lense.
The SBBOD (spinning beachball of death) can be caused by numerous reasons.
The program your using, the network your using, the internet, a slow/filled boot drive, too little or bad RAM, bad OS/app install or migration assistant screwups.
The networks stuff you can find out right away if it's the cause by disconnecting and rebooting.
A backup with a DU>erase w/zero from the installer disk, followed by a fresh install, update and install of apps from fresh cd's (not migration assistant)0 with files from backup, will do wonders.
A stock Quad is powerful CPU wise, but if it doesn't have enough RAM, and/or the boot drive is too big and filled up, Mac OS X performance will suffer terribly and these things will cause bottlenecks.
I have a performance text download you can take a look at, I don't see Spinning Beachballs

Mouse pointer jumping around and dock icon graphics tops breaking up

i been noticing my mac acting funny, at 1st i dismissed it as no big deal but now it has become more frequent. instead of happening occasionally its happening constantly. my mac has been in the exact same location since i owned it and my mouse surface hasnt changed. theres no debris i can see in the mouses eye. its like the computer is freezing then releasing the pointer. i cant even guess about why the dock icon graphic tops are breaking up. i ran my permissions and all is fine there. anyone else know what it could be? thanks for any help.

sweet the dock icons are full again. so far so good about the mouse. i forgot a couple months back i deleted my system folder(duh) and never reinstalled the techtool. i guess i paniced thinking something malicious was attacking my comp. sorry for assuming the worst. thanks for setting me straight.

Mouse pointer jumps to corners of screen

I am using a Mighty Mouse (wired) and have had problems with my mouse pointer jumping to the four corners of the screen. I then have to move the mouse around and find what corner it is in, and bring it back to where it was. It happens very often, and is very distracting.
I have had the same problem with a Microsoft wireless mouse and a previous Mighty Mouse.
Any ideas as to how the stop the jumping would be greatly appreciated.
Snoopyknitter

The suggestion to follow the cord was evidently the correct one. I had my Mighty Mouse plugged into the usb port on the back of my Mac keyboard. When I realized this (I have had it set up this way since I got my G5) I plugged it into one of the usb ports on the back of the monitor. In several hours I haven't seen the pointer jump once.
I will leave it set up this way and watch, but I think this may have been the solution. To think it was such an easy solution and I have been putting up with this for several years!
Thanks Thomas Bryant.

Mouse pointer jumps to corner of secondary screen

We just upgraded to a new server running the latest Solaris with Sun VDI 3.1 which includes Sun Ray Server Software 4.2. I have multihead enabled and have 3 stations with dual-monitors/Sun Rays. On the second monitor, especially when dragging or scrolling, the mouse pointer jumps to the top-left of the screen. All three of us are experiencing this. Two have xinerama extension enabled, one does not have it enabled and says he's seeing the same behavior with the mouse. We have mix of Sun Ray 1G's and 2's, and one I'm using is a 170. I did not experience this with our old server running SRSS 3.1. Anything I can do to fix this problem? I appreciate any help.

This patch is now in what's supposed to be its final QA cycle but if QA finds problems, or if a serious new issue is reported (especially if it's a security issue) then the whole thing might have to be rebuilt and possibly resynchronized with other patches in progress, and then retested on all supported platforms (which means reassigning QA resources that had been committed to other efforts). The best case for this patch that has reached this stage of the process might be two or three weeks. The worst case could be a month or two.
Alternatively, is there a hotfix available as many of our users are having difficulty at the moment.If you have a support contract then you can open and escalate a support call against the bug. After the escalation has been filed you can request an "IDR" ("Interim/Diagnostic Relief"), which is essentially an early build of the patch that contains the intended fix for that bug. The IDR will not have been tested by QA so there's some risk involved in taking it. This is one reason why we don't routinely publish IDRs. You have to decide whether that risk is outweighed by the pain the bug is causing.

Mouse arrow jumps around on the screen

mouse arrow jumps around on the screen

My iMac is unusable! If I click on a file the highlite runs down to the last file in the folder
When I boot up the hilight jumps all over the screen until it arrives at my startup drive.
If I type something and make an error it cannot be corrected, the cursor dances back to the begining of the sentence.
When clicking on the tool bar, eg. Safari "file" the cursor moves to all the other menu bar options.
I use "MacKeeper" for virus control. For a while it wouldn't load. Zeobit was able to correct that problem by remotely going into my computer and fixing everything the needed to be fixed. They solved that problem and the computer seemed fine. MacKeeper is currently checking all of my drives and partions. They also updated my virus library. This was yesterday (9/15/2012).
I scanned my startup disk this morning and it was clean. I also scanned two of my external drives as well as my internal drive. So far all are clean. 7 Drives to go.
I am running OSX 10.8.1 on an early 2008 iMac.
4 GB RAM
1.5 GB startup drive
3 external drives running on UBS via two docks.
3 External WD 2T external drives.
3 MyBooks drives via Firewire.
A total of 9 external drives with 15 partitions. All are Western Digital.
There has never been an issue with this configuration. I've been using Apple products since the "Fat Mac", twenty or so years. So I know my way around my macs, at least enough to solve any problems that have occured.
There are no authorized Apple techs in the country of Panama. Would sure appreciate help on this.
Thank you,

Dell M3800 mouse pointer jumps

I am having a problem with my Dell M3800 trackpad pointer jumping around randomly. I have adjusted all the options i can think of and it seems to be a problem with the driver or hardware.
The behavior is:
When moving the trackpad around, when i click (either a press or a touch) the trackpad pointer will randomly appear somewhere else on the screen.
* It is NOT a palm rest keyboard issue. It happens when I'm not typing - it is a clicking issue.
* I have tried turning OFF the "tap to click" option in the dell trackpad app (Sensitivity --> Tapping --> Tap to click) and still having the problem
I'm running the latest Dell trackpad driver, 17.0.15.85,A00.
Any ideas? Is this a confirmed problem? Hardware problem or should I maybe install the newer generic synaptics driver?

Is this the original Apple mouse? Do you have any third-party mouse drivers installed? (Look in System Preferences under "Other"). Presumablly you've tried adjusting the mouse sensitivity in System Preferences; have you also checked if the mouse if jumpy in other user accounts? If you can, try a different USB mouse on the eMac to ccheck it's not the hardware.

OSX update 10.10.2 causes mouse to jump around and text to be highlighted randomly in Dreamweaver CC 2014

OSX update 10.10.2 causes mouse to jump around and text to be highlighted randomly in Dreamweaver CC. When trying to click on a specific line of code in a js file the cursor ends up in a different place in the script and several lines of code highlighted. Clicking again jumps the mouse to a different position and even more lines of code highlighted and some characters rearranged, breaking the lines of code. Very frustrating.

Preran,
I am having the same issue. I have a MBP connected to 2 x Dell 27" monitors over Mini DisplayPort to HDMI cables. Once I updated to OS X 10.10.2 this cursor highlight/jumping around issue only occurs on the connected monitors. If I move the program to the main laptop display the issue goes away. It does not require me to restart the program or the machine to make it work correctly. One way I am able to identify the issue is if I go to the line numbers in code like I wanted to select multiple lines - in the one that works correctly, the cursor turns into a white version where the tip of the cursor points to the right. When it is wrong, the cursor stays black and will only have the tip point to the left. Its just another way I identified if it was working cause I tried uninstalling DW and reinstalling - didn't work. Reset preferences as you discussed - no go. And I used other editors like IntelliJ and Adobe Edge Code - all of which work fine and don't display this issue.
I tried the preferences reset you suggest and it doesn't work. I have another machine with OS X 10.10.1 on it and this issue is not there on any monitor. Any help with this ASAP as it pretty much stops you from being able to do any editing especially with longer pages as it consistently wants to page up when you select anything and if you then click again in another area it tries to move the highlighted code to that new spot.
Update: I have a USB Microsoft Arch touch mouse connected (always worked just fine). When I go to place my cursor at some point in the code it causes the highlight flicker. If I switch over and use the built in trackpad, then I can place the cursor without the highlight issue. When trying to select multiple lines or sections of code, that still see's the highlight, page up and move of code issues regardless of input type.

Pinkish glow around mouse pointer on external screen.

Since the last update (10.9.1) my mid-2012 macbook air started showing a very peculiar behaviour.
Only when connected to an external monitor and waking up from sleep, the mouse pointer on the external monitor comes with a pinkish glow. Very annoying.
Details:
- it only appears within the external monitor, if the pointer is moved into the macbook screen the defect disappear.
- to make it go away, it is enough to unplug and re-plug the external monitor
- it seems that the shadow and the aliasing around the mouse pointer receives the wrong hue on the ext monitor, but mine is only a guess.
- connection thunderbolt (original apple adapter to dvi)
- monitor iiyama prolite B2409HDS
- it started with the update to 10.9.1. NEVER had a problem before that (since 10.8)
any thoughts? Is there anybody out there with the same issue?

Same Issue here. See picture below:
Mac details:
Processor 2 GHz Intel Core i7
Memory 8 GB 1600 MHz DDR3
Graphics Intel Iris Pro
Software OS X 10.9.3 (13D65)
HDMI Cable connected to LG LCD TV
I'm not sure but it could be that I have started experiencing this glow since a Mavericks update ( I didn't have this issue the first months after upgrading to Mavericks).....
Did anyone already submit a bug report over here : https://bugreport.apple.com ????

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.

Mouse pointer jumping around screen!
