HiddenApp is a great little theft recovery program for the Mac.

After a computer is stolen the owner can activate the hidden app and set the wheels to recovery in motion. Think of it as a kind of “Lo-Jack” for your laptop. When the thieves or unlucky recipients of the stolen computer next log on to the internet, the IP address and other information is automatically sent to the rightful owners email address. The application will even utilize the Mac’s built in video camera to secretly take snap shots of who ever uses the computer after it has been stolen and send these to your email as well! For fans of spy movies and James Bond flicks, this feature alone is worth the very affordable price. HiddenApp claims that 90% + of stolen Macs that had “Undercover” installed on them, have been recovered. If you’ve invested in a nice new laptop for college or work this safeguard seems like it’s at least worth a look.
