Q: My cursor seems to have a mind of its own.

This happend about 2 weeks ago. I did another system update right after to see if there was a glitch. It is still doing it. It is like someone is moving it. Also my mouse pad is not working properly either (happened the same time). I am currently using a wireless mouse to still be able to use the computer but it also acts up. SUGGESTIONS PLEASE!!!!!??????

MacBook, Mac OS X (10.6.8)

    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 tested.
