Orbicule has released an update to its theft-recovery software for Macs, Undercover. Version 4 now allows users to remotely monitor a stolen Mac using the company's UndercoverCenter.com web interface. Devices can be followed in real-time, with a variety of information available from the website. The software can capture iSight pictures, screenshots, or log the current location as a Google Earth file. Users can also lock the computer and display a custom message.
