Looking at the tracking, my mac book is due in any day now! I'm pretty excited after spending some time doing a little more research. One thing I really cant find is: For me this is the very first time turning on an Apple product! Is there anything I need to do to the mac before using it? I read something about calibrating the battery so I know that much. Anything else I need to do to my brand new mac book before I really dive in and start learning how to use it?
