Trackpad & USB mouse not working
I'm having problems clicking on the trackpad - I plugged in a USB mouse and this won't click either.
I have tried repairing disks, applied pressure evenly across pad, loosened the screw underneath, cleaned it, taken the battery out to check if it's swollen, re-installed Lion and all updates.
I've also retstarted holding shift-L, ctrl, opt. This allows the USB mouse to work for about an hour and then it stops again.
It just seems to have happened out of nowhere - although other peculiarities to note recently, are that iTunes started to open by itself and play the first song in the library, even after quitting, it would re-open.
Surely this is a software issue if the USB mouse won't work either? Could really do with some help here!!!đ
