Q: The scroller on my macbook pro moves itself and the mouse pad is acting funny. Can you pls help me with a fix

If you've cleaned the MacBook Pro per Apple's recommendations, and if you've tested with an external mouse or trackpad (with no issues) and are still having problems with the internal trackpad, you'll probably want to make an appointment with the local Apple Store Genius bar, or with whomever maintains your hardware.

I had this happen four months ago and took it into the local Apple Store.  They ran a couple diagnostic tests and then the "Genious" said "Yeah, we're going to have to send it out for repair".  That took a week.  They said they replaced it (I'm sure with a "refurbished" one.)  Now four months later... same thing.  It's a sure bet I'll have to hand it over again for another week and get another crappy refurbished part that'll have a 95% probability rate of failure.

F-n Apple.
