I’ve been thinking about security lately, especially given that I’ve switched office environments. I went from a home office to to working at a serviced office suite — one that is also used by a group of people. While the individual room I’m in has a great group of people (several from other companies) and the room is key card controlled, I still would feel more comfortable locking my screen somehow when I get up for a few minutes to stretch my legs or get a cup of coffee or a bite to eat.
I’m often running some sort of program that I don’t want to stop, hence just shutting the lid of my (new!) MacBook Pro won’t cut it. Luckily Mac OSX Hints from MacWorld has a some hints on how to do just that:
The other solution I’ve been using is iAlertU, which is like a car alarm for the mac and also locks the screen. If moved, the motion sensor kicks off, it snaps a pic with the built-in iSight, and makes loud noises. And it is controlled by the remote that comes with the MBP.
