    Same mouse cursor jumping problem here after installing the ATI Radeon HD 5770 and a 27" LED Cinema Display on a Mac Pro (OSX 10.6.6). Also attached a second regular LCD display. The problem does not go away when you just don't switch on the second display. In my case removing the cable AND doing a "Detect Displays", which removes the second monitor setup completely, resolved the problem.

    I was still having this issue when I purchased the new multi touch track pad. I cannot say whether or not it is gone or just minimized but the problem seems to be reduced at this point. While I am not surprised to see how many other Mac Users have this problem I remain surprised that Apple seems more like Dell every day. Little concern for the customer after the sale. It is like the old Saturn car company, shower you with kindness while they actually do nothing. I will report back when the problem resurfaces or if it does not.

    YES! Thanks. Can't believe I didn't see that.

    I fixed mine myself.

     

    Reverted MacBook pro back to SL from that horrible OS X Lion, formatted HDD twice. Installed SL again as a fresh install and it's fine now.

     

    Touch wood

     

    Hope this helps

     

    Cheers,

    Scrap that. It's doing it again. As soon as I logged into the App Store it started.

     

    I shall be taking this MacBook to the apple repairer tomorrow. Shame I am a few months out of warranty :-(

     

    But seems to be a known fault so might be able to get repaired under warranty.

    If your mouse works on a plain piece of white paper, it means your mousepad was causing the problem.  Either too designy or textured.  Get yourself a very plain, one-color mousepad, in that case.

    An annoying side-effect of this is that it's almost impossible to turn off the display by placing the pointer into a "hot corner".

     

    Maybe this is a sufficiently big annoyance for Apple to start checking the issue?

    This problem began for me a couple of weeks ago and when active -- which can last for hours -- my Mac is simply unusuable. This is a mid-2009 MacBook (non-pro).

     

    No mouse, just the internal trackpad. This happens without touching the laptop at all.

     

    Here are the things that make no difference:

     

    • Restaring the Mac
    • Zapping the PRAM
    • Turning Bluetooth on or off
    • Turning WiFi on or off
    • Ethernet attached or not
    • Audio cable plugged in or not
    • Connecting an external Bluetooth Magic Trackpad or Apple Keyboard or not connecting them
    • Cleaning the trackpad
    • Having an external monitor connected or not
    • Having a USB hub plugged in or not
    • Having an external USB disk for Time Machine attached or not
    • The machine is hot from use or cool from a new startup after being unused for hours
    • Changing ventilation, laptop position, power plugged in or not
    • The geolocation of the laptop -- this happens in my home office, at the coffee shop, and at my girlfriend's place
    • Applications running or not -- it'll happen with every possible application and process turned off
    • Touching the computer or not touching it
    • Extra static grounding, on my lap, on a desk, on a table, doesn't matter

     

    So, I guess a new trackpad. It's long out of warrantee, though, so will likely be hundreds of dollars.

     

    Any other ideas?

    Mine was repaired under warranty. I spoke to a girl called Jewel at Apple Customer service and offered to pay for the part if they paid for the labour. She said she'd get back to me the next day and she did. She told me that Apple would cover the whole repair because I was a good customer as I pointed out that I have purchased a lot of Apple products.

     

    I was amazed that Apple did this. I had a faulty iPod many years ago and the customer service department in Australia were disgusting and refused to do anything even though it was in warranty and the problem kept happening.

     

    Hope this helps

    I have the same problem, adding a mouse pad only helps little.

     

    Finally, swapped another mighty mouse, which works prefectly.

     

    Meaning the old one is a faulty one

    I am having this same problem, I've had it before and somehow I fixed it but can't remember what I did. This happens on both my USB Mac mouse that came with the computer (Mac Pro) and also with a Wacom Intuos 2 tablet (USB) that has a mouse.

     

    One thing I noticed is that if I log out of my account and log into the guest account, the problem does not occur in the guest account. So it has to be some kind of software thing. The only software that I have updated recently is the Apple Software Updates. So frustrating!

    I like your logical approach. Here's another piece of the puzzle. I have a Mac Pro at work. The Mighty Mouse is very stable on it. At home, I have an iMac. A Mighty Mouse is virtually unusable on it because of the "jump" problem. Sometimes it will also open and close windows very rapidly without even touching the mouse. Very entertaining. The only way I can tame Mighty Mouse is to ground myself to the iMac frame. I've tried this by just toching the bottom of the iMac with my free hand, and also by using a grounding strap attached to the iMac and my wrist (guess that's why they call it a wrist strap). Remove the ground and the jumping starts afresh. I believe it's something in my home work area that's generating RFI, and my body is acting as an antenna. Lord knows there's enough electronic stuff in my home office. I would think the Mighty Mouse would be grounded to the iMac through its USB connection, but whatever ground is inherent in the system is insufficient to handle the RFI.

    I'm happening both of your issues, Dual Display and mouse moving randomly. With Leopard it had been worked very well, since I bought a MacBook Pro, I started to have several issues that I nwver had with Leopard. It is possible to downgrade?

    I had my trackpad replaced once when my macbook was relatively new becuase of this problem, and then today,18 months later, I have it happening all over again. I think it is a hardware problem, because it was fixed when it was replaced.

    I've been having this problem (see post above) but I figured out what the problem was. It was the Wacom tablet drivers. When I installed updates to the drivers, I needed to uninstall the old driver first but I didn't, and the new drivers caused both the Wacom mouse and my regular Apple mouse to randomly jump all over the place. Once I installed the Wacom drivers properly, everything has gone back to normal and I haven't had a problem since.
