Dear all, First of all I'm newbie for MacOSX, I just bought macbook pro 15", it's .... (no word enough to describe it). I usually use windows. I have a couple of questions: 1. Is there hibernate in macosx? if so, how do I activate it? 2. From what I search on the google, sleep is the closest thing that close to hibernate. Is it save to travel on sleep mode? 3. how to lock the desktop when I leave for a moment. Thanks and pardon my english.
