    The issue resolved for me after I used an external mouse for a few days. I turned off my trackpad while the external mouse was plugged in and the problem went away.


    Other people have had success cleaning the edges around the trackpad with a toothpick or a dry cotton swab.

    I can't believe this was so easy to solve. I really thank you for your help!

    Do you know the name or the link to the YouTube video that helped you fix your trackpad issue? If not, can you please provide me with more specific instructions on how you were able to fix your trackpad, thanks!!!

    I made an amazing find. My trackpad started acting irratic - jumping, dragging - basically possessed or infected. Long story short - I had installed a Philips HD TV on the wall above my desk. Just being near the HDTV - within 3 ft - causes the issue. When I move > 10 ft away, the problem goes away. Worked for me.

    I didn't watch the video that Stickykees mentioned. I just press the trackpad with my entire hand (the palm of my hand) for about 3 seconds. Just it, and all the erratic behaviour of the trackpad just dissappear.

    Hope it helps.

    Hi, just wondering if anyone could help, I've a Macbook Pro (late 2011) version and my trackpad has been running rather erratically (mouse pointer moves on it own, opening of folders? dragging tabs and recently it's been unresponsive even with a usb mouse plugged on. I've even tried tapping at the four corners of the trackpad and it doesn't work in anyway as well.


    Ps; the warranty has already expired hence that why i'm hoping for some answers!

    I had the same symptoms, and fixed it by replacing the battery, which cost about $110 online plus $8 for tools.  Get the vendor to confirm the right battery for your model before ordering, there are a lot of versions.

    The definitive answer to this problem is as follows.


    Grounding issue can cause this. (bad adapter)

    Swollen battery can cause this.

    dirty trackpad can cause this (MOST OF THE TIME )


    Here is a test you can do. When it starts acting up and opening windows, take both hands and apply pressure evenly to the entire trackpad rubbing back and forth for about 30 seconds to a minute. If the problem goes away, take out your trackpad and clean the edges of both the trackpad and the trackpad hole. Be very gentle or have a certified mac tech do this for you. Once you have cleaned and reseated the trackpad it should be Gold!

    I can't believe this actually worked! Who would have thought something so simple as moving away from the HDTV would solve the issue of an erratic mouse! I was trying all sorts for ages today trying to solve it! Thank you!!!!!

    This saved me SOOOO much time and frustration. I was about to pull my computer apart! Thank you so much for your insight. This is exactly what my issue was. Guess I never paid attention to the fact my battery was swelling up! Who knew!!! haha

    Was having the same problem, macbook was completely unusable without external mouse.


    Updating to Yosemite completely fixed problem for me.
