I use my Mac for a BUNCH of things, and in doing so, I need it to a bunch of things. Many which it can’t do out of the box. Primarily keeping it form going to sleep when closing it. Awhile back a good friend had an acer which he would close and through in his backpack. The cool though was that he had iTunes running while it was in his backpack. Another reason I kinda wish it would stay awake while closed is when I hook it up to my TV I have to turn my computer around, because having another mini display of the TV is just damn annoying.

This is were the nice little mac app, InsomniaX by semaja2, comes in to play. After downloading and installing you have the option to let the Mac run normally or in insomnia mode. Which of course keeps your mac awake even when the lid is closed. It also gives you the advanced features of choosing to just put the display or the system and the display.

So there ya go. I know this app has a home on my Mac. Hopefully it helps you out too.
