TheftSensor is a brand new application that makes it easy and fun to protect your MacBook. Simply press the play button on your Apple Remote and TheftSensor will be activated. From now on, moving your Mac will trigger a loud alert. Pressing the mute button won't help a potential thief as TheftSensor disables it. The same goes for closing the MacBook's lid: this will trigger the alert as well. Of course, you can still use your MacBook without launching the alert: simply press the play button again to disable the alert. View the video and see TheftSensor in action. Or - if you are lucky enough to own a MacBook - download the free public beta.
