Hi, I've had my first mac (a 13" macbook pro) for a week, have never used wifi or bluetooth before, and have two security questions.. When installing OSX I connected to my wired ethernet router and went through the account setup giving my full real name, full address, email etc. and my first name as the short name. I gave accurate details thinking this was for live online registration with apple. I then found that my computer name was set as "<firstname> <surname>'s MacBook Pro" and it was all only for the admin account setup on the machine. I've been using it for a week like this and I just found that AirPort was enabled by default and I can see all my neighbours listed as wifi hotspots. This now worries me, could my neighbours also see my computer name on their wifi lists as "<firstname> <surname>'s MacBook Pro"? If so this is telling everyone in the area that I have a Macbook Pro and they could find my address in the telephone directory from my surname! I have the Internet Sharing options disabled (the default) so I guess knowone could logon to my computer and use it, but if my full name is on their wifi lists it's a risky default configuration. I've now changed the computer name and disabled AirPort. Also, I want to use a bluetooth printer, keyboard, mouse and camera. If I enable bluetooth on the MacBook how will it show-up on neighbours machines? Thanks, Chris.
