MacBook Pro glitch with chaotic automatic clicking and no control over track pad.
Basically, the problem is in the heading. My MacBook Pro goes crazy from time to time and I lose the control of the track pad (sticky, jumpy cursor). Also it makes automatic clicking resulting in chaotic opening of windows and programs, resizing windows and what not. In these moments my computer gets a life of its own. I can somewhat get the control of the cursor by connecting mouse with USB cable (this is how I'm able to use this forum now).
I was suggested testing the computer in Safe Mode before. I did it and during Safe Mode cursor was OK. Anything else was impossible to test because of the strobing of the pages and windows in Safe Mode
