Q: Erratic trackpad fixed temporarily with external mouse
I've been having issues with the trackpad on my Mid 2012 MacBook Pro lately, where it acts erratic and goes from jumping around, to staying completely still, to clicking things that I never meant to. There aren't any updates for my laptop either, as I currently have what I believe to be the most recent installment of Yosemite, and my computer is not notifying me of any possible change.
I've had this issue occur before but on a lesser scale, and I was able to fix it by simply going to the trackpad system preferences, unchecking everything, and then rechecking everything. This time, however, that method's only worked for about five minutes or so before it went back to acting strange. Eventually, I found an old Logitech plug-in mouse that I've been using so far, and I've discovered that when it's plugged in the trackpad works just fine, so I took out the mouse and the trackpad began working for about twenty minutes before it acted up again. So, again I plugged in the mouse, but this time, the trackpad worked in spurts where it would be fine one minute and act up the next. I've also shut down my computer entirely and waited anywhere from a few minutes to overnight completely, which would once again fix the issue for the first ten minutes of use once I turned it on before it began going haywire.
Any help would be appreciated as I'm totally lost with this. It might be a while before I can carve out some time to visit an apple store myself, so if I could get this fixed on my own that would be wonderful. Also, apologies if this was placed in the incorrect community/category. Thanks in advance (:
MacBook Pro, OS X Yosemite (10.10.2)
