Hello! My macbook started freezing every time I started it. MacBook Pro (Retina, 13-inch, Late 2013) I did the usual, reset PRAM and SMC, even reformat, etc. After doing that, I noticed that if I kept moving the mouse, my computer would no longer freeze. if I stopped moving the mouse, then the computer would freeze again. The computer doesn't have this behavior if I start it in safe mode. That's really annoying!
