So... I'm sure everyone hates noob posts, but here is mine. I have spent no more than 30 minutes of my life on a Mac...and it was all basically surfing the web. I ordered my first Mac (and first laptop), which should be here tomorrow. It is a MacBook Pro model mb47ll/a. My question is this... Aside from update, is there anything else I should do right away? I've read a little about calibrating something or "zeroing" the hdd....whatever that means exactly. I've been a PC user for a long while and am eager to finally step into the world of Macs. I can thank my iPods and ultimately my iPhone for convincing me to take the plunge. Any helpful advice, tips, or direction for a clueless noob would be greatly appreciated.
