TheftSensor for MacBook
Orbicule has unveiled TheftSensor, an innovative alarm system for the MacBook Pro. "Taking a page from the car alarm, MacBook Pro owners can enable TheftSensor by pressing the play button on their Apple Remote. When enabled, TheftSensor will start a loud alarm whenever the MacBook is moved, lifted or when its lid is closed. The alarm can be disabled by pressing the play button a second time." TheftSensor uses the MacBook's built-in sudden motion sensor (SMS) and the Apple Remote. It is currently available as a free public beta and requires Mac OS X 10.4.
