Sorry if this sounds a little stupid but this is my first macbook. Selling it tonight to fund a new i7 MBP ( own a C2D now ) Was curious of a few things.... 1) How do i format it so its a fresh install of OSX and ALL my info is GONE? ( i never really looked in the box when i got it, so i am not sure if they come with a OSX CD or if its on a partition or if you do it another way? i am use to windows. 2) how long does the clean install normally take? Reason i ask is because i do not want to do a clean install and then have the buyer NOT show up and be stuck reinstalling ALL my stuff. So if its a rather quick process i can do it while he/she is here waiting.
