Sometimes it does, like right now I was watching a video on facebook and then swiped the mouse to get to the the Mail app and it just froze. I had to unplug and reboot it. Does this happen to you often as well? The Mac is only 3 weeks old and purchased brand new at the Apple Store. I guess I'm just unlucky with Apple products like the Magic Mouse 2 which is pure crap it gets micro scratches as soon as you unbox it, I'm on my 3rd one in a 2-month period.
