Hello everyone!


I've just updated my iMac to the lastest version of Mountain Lion and now the Magic Trackpad is clicking or selecting text (and deleting it) by itself. I've changed the batteries twice and is not a problem with it.

I don't know what else to do and I don't have a mouse or a substitute for it right now.


Thanks in advance.         

iMac (21.5-inch Late 2009), OS X Mountain Lion (10.8.2)

    You are not alone my friend - I have this problem too


    Since 'upgrading' to OSX 10.8.2 my Magic Trackpad is 'magically' clicking and right-clicking stuff all by itself...


    Only happened since 10.8.2 so nothing to do with the hardware.


    Having to use internal trackpad on my rMBP now as Magic Trackpad is unusable until this bug is fixed


    Hopefully, we won't have to wait too long for Apple to identify the cause and get a fix out...

    If you are running any apps full-screen... don't!


    I was running Parallels and iTunes in full-screen, and as soon as I changed them to windowed mode, the trackpad problem went away.


    Don't know why, but they are definitely related!

    I took it to an Apple Premium Reseller and they finally gave me a new one because the "ghosty" was unrepairable, so if the problem persists, I suggest you to do the same I did.

    Anyway, thanks for your message.
