Hi, I'm having problems with my new MBP bought around 20 december. It sometimes freezes, "hangs" up, when Im trying to turn it of from the menu, and then i have to force quit it by holding the powerbutton. What could be causing this? This is usually after ive had it just in sleep mod every night for about a week. Is there anything i could do? I tried searching the forums but i didnt find any answers. Thx for all answers.
