Trackpad, keyboard does not work
I was on safari in facebook, using the twitter app for mac and smc fan control, but when I had smc fan control off all was ok, when I executed the trackpad, keyboard and speakers went wrong.
USB and headphone jack works, but the other hardware no
How can I fix this?
I have OS X Mavericks 10.9
Mac Pro, OS X Mavericks (10.9)
