I've just received my new MacBook Air. (my first Apple computer in 15 years!) Unfortunately, I had it sent to work on a day I wasn't in, and it was mistaken for the new intern's computer. He proceeded to do whatever it is one does with a new mac when one first receives it.
I have the admin password he created, but I imagine I need to do a full wipe to be sure the computer hasn't been tampered with - i.e., a login script exists that maliciously exports my data.
What steps should I take to secure my laptop? What registration etc. information might I need to correct that one enters upon starting up a new MacBook Air?
