Hidden is an app that claims to help you track down and find your Mac -- it runs in the background of your desktop computer, completely invisible, and only starts to send out location information when you actually go to the Hidden website and choose to flip it on. That way, if your Mac is ever stolen, you can log on from any computer and immediately get updates on where your stolen computer is, helping you track it down as quickly as possible. Getting it back is up to you, but just finding a stolen or lost computer is often all you need to do to provide proof that it's yours anyway.
Our own Steve Sande really liked Hidden when we first wrote about it a few months ago,
