Erratic Mouse pointer

Hi Guys i am new to mac i just bought one, can you help. My mouse pointer seems to intermittently dart off to the corners of the screen now and again. I have the optical usb mighty mouse, can it be faulty or does it not like my mouse mat??? i have tried it with different user profile and safe mode.
Thanks in advance

I used to have problems with my optical mice jumping around on the screen. Apple's optical mice are very sensitive about changes in the texture of the surface they are on. Patterns need to be very consistent, and very regular.
I finally found my cure. It was a WowPad.
http://www.microthin.com/prod_wowpaddesigns.htm
I purchased the "Dots 007" pad. It's the grey colored pad.
Since getting this pad, My mouse has been very well behaved.
I think it was $5 or $10 at Office Depot in Seattle Washington.
I'm not in Washington, but I purchased it while visiting last year. I like the pads that are very thin like paper. And, I couldn't find any in Alaska (my stores quit stocking thin pads).
Further, I like them to be firm (not the spongy rubber).
So, in my quest for a paper-thin, firm, and optical compatible pad, I looked everywhere. Finally, the last store I went to, I found it.
I looked all over Alaska, and all over Washington (while driving around), and was about to give up. But, I got lucky and found one at the Office Depot store. So, I purchased a handful of them to keep me stocked-up.
Anyway, look at your local Office Depot. If they don't have them, consider ordering one from the website I listed.
Hope this helps you out.

  • MBP behaving weird. Often mouse pointer goes erratic, then freezes...

    After half a year usage, my MBP starts to behave strangely. The problem starts with mouse pointer gets erratic. That means, it does not respond to my finger stroke on the trackpad. When it does it moves really fast. Then the computer freezes and I have to force shut down. I still can't quite find the pattern of it. I often run cocktail clean up. I use disk warrior the graph the state of the hard drive and it shows 36% if items are out of order. Is this the main cause? I will try to rebuild directory with diskwarrior later. I only have about 8-9 gb of free space left on a 120gb HDD. I gave 32gb to windows partition. Would it be the culprit of the problem?
    Could someone help? I really want my MBP back to the way it used to be - STABLE, FAST.

    Could you explain more about what DW says about 36% of items out of order? And what does DU say about your SMART status? And what brand of hard drive do you have? I am beginning to wonder about the state of your hard drive. If you have directory problems that Disk Warrior cannot fix, then maybe that is why you can't create a bootable clone. And maybe there are problems with your hard drive that go beyond just the directory.
    There is a little program cqlled S.M.A.R.T. Utility you can download and run several times for free that can tell you quite a bit about your hard drive if your drive is supported:
    http://www.versiontracker.com/dyn/moreinfo/macosx/32454
    You might also try running the Apple Hardware Test and see if anything shows up in the form of an error code.
    I assume that you have verified both permissions and the drive and have attempted to repair both. And that there is something that cannot be repaired. Is this right or have I misunderstood you?
    If your problems are being caused by your hard drive going south, then that could happen with any computer, including a PC. I have heard about some Seagate models failing prematurely. Also some unfavorable comments about Hitachi drives. Check out what you can about the health of your hard drive and post back before going to the trouble of a format and reinstall.
    Good luck!

  • Mouse pointer is erratic.

    Hi folks.
    I have a problem in Logic where the mouse pointer doesn't always show the correct icon for the underlying control, this can make simple tasks like selecting volume nodes, or mini notes difficult.
    It's not a show stopper but I wonder if there is a way to fix the problem.  I've had the problem since installing and through a couple of updates.
    Macbook Pro
    Logic 9
    Everything is always updated to latest versions.
    Cheers.

    Thanks for the reply.
    I usually work in full screen mode, but it happens in sized mode too.  Is this more to do with the OS?
    Cheers.

  • Mouse pointer has gone mad on NB100

    Started a download from the iTunes store, came back 30 minutes later to find my mouse pointer jumping erratically in a vertical direction. Had to disable the synaptics pointing device driver and plug in a USB mouse. After rebooting and restarting the mouse driver it appeared to work mostly correctly again until today where it's doing the same thing.
    Has anybody else experienced this? I'm coming to the conclusion that the touchpad and keyboard on this device are just very poor indeed.

    Hi,
    Thanks for your reply. I uninstalled the Synaptic driver and installed the Microsoft one. Still does it, although it is intermittent. When it happens, if I tap the touchpad in the right place it stops. So, it does look like there is something wrong with my touchpad.
    Once I back my HD up I am going to revert back to the original factory install. If it still does it then - and I'm fairly sure it will - I guess it's off to Toshiba to get repaired.
    I wouldn't mind so much had it not been for the fact that the netbook has had very little use indeed - maybe as little as 100 hours in total as I tend to only use it when on holiday / visiting the parents.

  • 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 shacke by pressing touchpad

    Just by pressing the touchpad and let the tip on my finger on it the mouse pointer starts to shake like a centimeter. The problem disappears and comes back erratically. This is really annoying.

    hey nekonoko,
    welcome to the forums.
    uninstall the current touchpad drivers for your unit. let windows install its generic drivers.
    test with generic drivers and see if that makes any difference.
    later, head over to http://support.lenovo.com , download and install the latest touchpad drivers for your unit.

  • Jumping mouse pointer

    I've seen other posts describing a problem similar to mine. But I have not been able to resolve my problem. I'm hoping someone can suggest a resolution. I'm using my Mac Pro (early 2009) with a 4850 graphics card. I have always had 2 monitors attached. Both are Viewsonic. One is a 19" VA1930wm. The other is a 22" VG2230wm.
    For a few months now, I've noticed that my mouse pointer will jump around on the screen, making control very difficult, especially when playing video games. I took my Mac to my Apple Store to have it checked. They ran several diagnostics and were unable to replicate the problem. Btu here at home, I continue to have a problem. I thought it was a problem with the blue tooth, but I also have the problem when using corded mice.
    The other day, I bought a new corded mouse to use. I noticed that the jumping problem was very consistent. It happened at a very constant time interval of about 2 seconds. As I considered this, I realized that when they were diagnosing the problem at the Apple Store, they were only using one monitor. So I decided to disconnect one monitor and see what happened.
    I disconnected the 22" monitor, leaving the 19" connected. Immediately, the mouse jumping problem went away. Then I decided to switch monitors. I disconnected the 19" and reconnected the 22". The problem came right back. I then switched the 22" monitor between the two video ports. It didn't matter which port was used, the problem persisted.
    I contacted Viewsonic and, after some discussion, they gave me an RMA to send the monitor in for maintenance. My question here is whether it is a problem with the monitor or if it could be something else. If anyone has any suggestions, I would appreciate hearing them.

    I just got a new mid-2010 8-core mac pro and this same problem is occurring for me. I have a logitech mx revolution and when I first set the system up from scratch it wasn't working well so I switched it out for the magic mouse it came with. The same thing was happening with that. I then tried magicpref to see if that somehow fixed it. It didn't. Since then I've removed the logitech control center and magicpref utilities and even tried a wired mouse. I'm still having the erratic mouse movement.
    I haven't tried disconnecting my second monitor, but what's strange is when I start up the mac pro the secondary monitor flickers for a few minutes. I have no idea why it would do that or if it's related...

  • 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.

  • MacBook Pro SMC Firmware Update 1.3 update freezes mouse pointer

    After installing the update released today 5/28 (MacBook Pro SMC Firmware Update 1.3) my mouse pointer stalls, freezes on occasion. Very annoying. Anyone seeing the same. Fixes ... ?

    After applying the SMC Firmware update a few days ago, my keyboard and trackpad were acting erratic (freezing, hanging). It was immediately after the update and I had not had any problems with it before.
    I have also had random crashes, inability to use the keyboard/trackpad ever since.
    Today my keyboard and trackpad are completely unusable, external mouse works fine.
    I will take it to an Apple store tomorrow, hopefully my firmware can be reverted.
    Sounds like a lot of other people are having problems with this update. http://discussions.apple.com/thread.jspa?messageID=9549034&tstart=0#9549034

  • How can I correct Unstable, erratic mouse cursor movement

    I currently have a dual boot setup with Windows 7 Pro 64 and XUbuntu 64 bit XFCE desktop. On random occasions, the mouse pointer will begin to float and or will not stay positioned on the spot selected.  This occurs with or without an external mouse attached.  The track pointer will not control the mouse and neither the left nor right keys just below the keyboard function.  The drifting will stop sometimes when the center key at the bottom of the keyboard is pressed. The touchpad and its keys seem to work correctly.  I have turned off both of these in the BIOS and have not had any problems.  It seems to me that the problem may be with the keyboard. Any body have any experience with this sort of problem?  

    Hi
    Thanks for your post
    To  help you further on this issue please share more details
    1. erratic mouse cursor movement  is happening  in win 7 or ubuntu
    2.  please share the touchpad driver version   &  bios version
    Cheers!!!

  • Weird mouse pointer behaviour

    Since this morning OSX won't register the position of my mouse pointer. All the hover triggered events (link highlights, Expose Hot Corners) won't work. OnClick events do work correctly, but it is kind of annoying not being able to use hot corners.
    Any ideas on how to fix this?

    Something is up with the 10.5.6 update. Bluetooth mice pointer is erratic, but buttons all work fine. Mouse is fine (Great: ROCKETFISH) on all other Macs. Mail.app, SyncServer and other non desrcript and arcane named processes are sucking the goodness out my MacBook 2.16 Mid 2007. Fans are going much more than it ever did...battery is being drained by processes I never evoke. Crashes from BAD_ACCESS plagued me on 10.4.11 so I took the plunge....bought Leopard....and spent days trouble shooting all the messes it casued...had to search for Mail.app update....never showed up in the software updater process....that is not acceptable....I have bought new hard drives, thinking it was a faulty drive...not enough free space.....nope. Spotlight was eratic at one point. I run Disk Utility and ONyx regularly and often the permissions are wrong on a big scale....run it again and the same ones are wrong again....run it off the Installer Disk....Get everything apparently tickety boo....then the Bad Access thing reals its ugly head again....I am tired of being a beta tester...this is not my bling thing toy...it is my living and I spend more time doing trouble shooting than work....Genius guys are a misnomer....Apple is starting to drop from the top of the tree and is looking rather fetid mixed with the compositing leaves....enough CRAPPLE give me the good Mac stuff once again....System/Finder 3.7 wasn't this bad. Who needs a million bells and whistles if you can't the 'trailer hitch' to work? Tech tool shows all is well.

  • IMAC and external screen--screen flickering and erratic mouse behavior

    I have purchased a screen Medion 25.5 inch to connect it to my IMAC 27 inch.
    I have noticed two unexpected behaviours:
    - from time to time, after the IMAC comes out of the SLEEP mode, the external screen is flickering, I need to put the IMAC to sleep one or several times before the display of the external screen becomes stable.
    - since I connected the external screen, the behavior of the mouse is highly erratic, eg when I move the mouse by a fraction of a millimeter, the display of the mouse pointer moves by half a screen, or even disappears completely. I have performed many tests, with several apple mice, a Dell mouse and a Microsoft mouse. As soon as I completely disconnect the screen (not only power the screen down) the mouse works normally again. I have now decided to stop using the external screen until a software update resolves the situation.
    Any advice?
    Patrick

    When my 2008 24" iMac started to die from overheating, two of the symptoms I would see would be white flickering from the bottom going about half way up, like it was going blank and repainting the screen over and over. Also, the mouse pointer would jump erratically to all the edges and corners of the screen. After a few seconds, it might recover or it might freeze. I would use a program like iStat Pro to see what your temps are when you attach that screen. I suspect it may be excess heat due to the GPU now pushing two screens instead of 1?
    Also try diags, and all those reset thingies people keep mentioning over and over.
    First and foremost, if you have coverage, contact a "genius" and let him belittle you with his expertise.

  • Ghost circles and erratic mouse behavior

    I have these light colored circles in the upper to middle left part of the screen and my mouse keeps jumping to these dots and I have virtually no control of my mouse. Is there a real solution to this problem as I have already hundreds of posts about it but no apparent actual fix.

  • Safari won't open and wheel (mouse pointer) keeps spinning

    Hi guys.
    I'm going crazy here as everything I've read and tried doesn't work?
    I've deleted cache files, history, plug-ins etc etc and every time I try and launch Safari, I keep getting the spinning wheel/beach ball/mouse pointer and safari doesn't open?
    I've received the following long error message and it may as well be in Arabic as I haven't got a clue what it means?
    Any techies out there who could shed some light "Error message for dummies' style please?
    This is the report error.
    Cheers,

    You installed the "DownLite" trojan, perhaps under a different name. Remove it as follows.
    Malware is constantly changing to get around the defenses against it. The instructions in this comment are valid as of now, as far as I know. They won't necessarily be valid in the future. Anyone finding this comment a few days or more after it was posted should look for more recent discussions or start a new one.
    Back up all data.
    Triple-click anywhere in the line below on this page to select it:
    /Library/LaunchAgents/com.vsearch.agent.plist
    Right-click or control-click the line and select
    Services ▹ Reveal in Finder (or just Reveal)
    from the contextual menu.* A folder should open with an item named "VSearch" selected. Drag the selected item to the Trash. You may be prompted for your administrator login password.
    Repeat with each of these lines:
    /Library/LaunchDaemons/com.vsearch.daemon.plist
    /Library/LaunchDaemons/com.vsearch.helper.plist
    /Library/LaunchDaemons/Jack.plist
    Restart the computer and empty the Trash. Then delete the following items in the same way:
    /Library/Application Support/VSearch
    /Library/PrivilegedHelperTools/Jack
    /System/Library/Frameworks/VSearch.framework
    Some of these items may be absent, in which case you'll get a message that the file can't be found. Skip that item and go on to the next one.
    From the Safari menu bar, select
    Safari ▹ Preferences... ▹ Extensions
    Uninstall any extensions you don't know you need, including any that have the word "Spigot" in the description. If in doubt, uninstall all extensions. Do the equivalent for the Firefox and Chrome browsers, if you use either of those.
    This trojan is distributed on illegal websites that traffic in pirated movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect much worse to happen in the future.
    You may be wondering why you didn't get a warning from Gatekeeper about installing software from an unknown developer, as you should have. The reason is that the DownLite developer has a codesigning certificate issued by Apple, which causes Gatekeeper to give the installer a pass. Apple could revoke the certificate, but as of this writing, has not done so, even though it's aware of the problem. This failure of oversight is inexcusable and has compromised both Gatekeeper and the Developer ID program. You can't rely on Gatekeeper alone to protect you from harmful software.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

  • When a link is rolled over by the mouse pointer a very annoying pop up with the link address shows up. There seems to be no way to prevent this from happening. How can this pop up be made to go away?

    no matter what website, every time I move the mouse pointer over something to click on a line of black printing in a thin white box pops up at the bottom of the screen and shows me the http address of the item I'm about to click on. I want to shut this function off or remove it if possible. I find that the previous version did not do this, it seems to be unique to 6.0. It's VERY distracting and ANNOYING. How can I make it go away????

    When you hover the mouse cursor over any link, it will display the link details at the bottom left of the screen; black font on white background.
    This display can be very important as it shows the full address of the hyperlink. This can be particulary useful for checking on whether the link is bona-fida. For example; if you receive an email that looks like it is from a bank , hovering over the link will indicate instantly that the link is pretending to be something it isn't.
    Another example that can be useful; a website link may say 'contact me' rather than give the actual email address. However, when you hover over the link, the actual email address will be displayed at the bottom of the screen. If you click on the link then Outlook usually opens, however I do not use Outlook, so displaying the email address is useful.
    This display is something that has always been present and it is also displayed if you use IE.
    However, I can see that this annoys you, so you could try the following:
    [[https://addons.mozilla.org/en-US/firefox/addon/link-location-bar/?src=api]]
    After installing the addon, you will need to restart Firefox, then go to History and Restore previous session to get all your tabs and webpages back.
    You will now find that when you hover over any link, it will now display in your address bar on the right hand side.
    If this helps, please say this question has been solved.
