Orbicule today announced TheftSensor, a new 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 is available as a free public beta.
