iPanic

It’s true, Macs do crash, but rarely. When your Mac does crash, you get a pretty little message that says you have to restart your computer (Kernel Panic). I guess you can say it’s equivalent to Windows’ Blue Screen of Death. A simple app called iPanic lets you simulate this Kernel Panic, only you don’t have to reboot. Great for tricking your Mac friends into thinking there’s really something wrong with their computer!
