A blog “More Willie” has a great post about Crucial Mac software for students. My favorite application is iAlertU. It’s an alarm for your laptop. You arm the alarm with your IR remote and it beeps just like a car alarm. Using the built in motion sensor it can detect if someone moves or tries to use your computer. If they do an alarm sounds and the screen starts flashing. It also snaps a picture with the built in iSight camera. Click here for the Crucial Mac Software: College Edition.
