Q: Glitching trackpad :/

I am wondering if anyone knows how to fix a Mac Pro trackpad short of paying gobs of money.

 

Here's my problem: the mouse will, on its own whims, jump across the screen, select items, highlight, not respond to touch when I do want to move it etc.

 

If there is a way to fix this, and quickly, please, please let me know! I would really appreciate any kind of help here.

MacBook Pro, Mac OS X (10.7.5), 2011 laptop

    Try the tips suggested in this article from Apple.

     

    http://support.apple.com/kb/TS1449

     

     

    If this does not help, you have to take the computer to the Apple store to have it checked out.

     

    They may be able to clean, tighten the trackpad if loose and check the battery.

     

    Best.

    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. Reset the System Management Controller.

    3. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.

    4. 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.

    5. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.

    6. If none of the above applies, or if you have good reason to think your computer is being controlled remotely, disconnect it from the network by turning off Wi-Fi and Bluetooth and unplugging the Ethernet cable or USB network device, whichever is applicable. If the cursor movements stop immediately, you should suspect an intrusion.
