Trackpad going insane and clicking on everything

3 days I've been wrestling with this. Thank you. It worked.

That does sound irritating, but probably not a lost cause. I would definitely take this in to an Apple store if you have one close at hand. They can do a diagnostic and probably tell you what it will cost to fix, assuming it is out of warranty. Of course if it is under warranty or an AppleCare plan it should be covered.

Best of luck.

have you checked if you do not have a bulging or swollen battery, or grit stuck on the edges. I presume that's on your macbook?

Have the same problem. Started a few days ago. I checkek the box to disable the trackpad when an external mouse was being used. Everything works fine. I guess I need to replace the trackpad. I hope it is still under warranty. Computer is less tha a year old, so it should be.

All the best, they should give you the reason and also since you're mentioning your battery, it;s prudent to have that checked out too

i have the same problem... my trackpad is crazy since yesterday... i'm very sad beacause with the old version of mac os X, there had a possibility "to disconnect" the trackpad... but now we can't... (sorry for my english)

i think i have to go in the apple store...

i find strange that we all have the same problem in the same time.. you have the version 10.8.6 ??

try going to preferences-universal access-trackpad options...........there you can disable the trackpad when using an external mouse.........it worked for me.............now i need to get the trackpad fixwed or replaced, but at least i can use the computer......

OOOOh thank you pal36, i only search in the category "trackpad", just near to "mouse" 😀. it was logical for me that i can disconnect the trackpad in category trackpad...

tomorrow, someone from apple will call me at 10:30 (french hour), i will see what he says and if he has a solution, i will write it here !

thanks a lot for the trick ! about now, it work for me too.

Ok, then...

Apparently, there are 2 solutions and it's possible that it does not work :

1) first we have to save our important files and reinstall the system. With this solution, you need some place on your hard drive because the "new system" replaces the old without clear the old who became like a ghost on your hardrive. Normally, you don't lose your contents but save the importants files is a caution that i advise

if this solution does not work, we can try the second solution...

2) clear all the system, clear all, and reinstall the system... this solution clear all, so, save all what you want befor !!!

if the second solution does not work too, the woman says that we only can send our macbook to an apple center. I ask her for the price, she answers me that just the apple center can give the price, she can't estimate the price.

if someone want to try, say the result here please.. because i can't try this for moment...

again, sorry for my english, we have a bad level in france 🙂

ps : if you don't understand what i say, i will try to explain better

Good to hear it's sorted

Hello! I do have the same problem.. I was babysitting my friend's sister and she was just playing on my computer.. tapping on the key board.. I dint know if it could cause me this much hassle.. my computer now works fine sometime and sometimes it just starts clicking on everything.. LOL. I don't have warranty scared to even take it to the store.. thinking how much its going to cost me. I did go to the best buy where the guy at the register ... shouldn't be a professional but told me it might cost me around $ 300.. idk if it is a permanent damage.. =(

Well my problem seemed to fix itself after a while. Using an external mouse works fine. Then the trackpad seemed to work fine also. However the problem came back a short while later and started to click on things all over the place totally on its own. I'm under warranty until July so I guess I better get it in and checked out unless anyone knows something I should know.

I had the same issue , try to work on ur mac while not charging it it'll work normally .
