versiontracker.com — It always has been a missing feature: disabling the sleep mode on a Apple Laptop. Who does not want to use it as a big juke-box or go warwalking. The best looking server ever, especially at about one inch height. This small utility is what you will want, this small utility acts as a wrapper to the Insomnia kernel extension, say hello to InsomniaX

I've seen more portable than a powerbook ;) Especially when we're talking of MP3 players.

Uh yeah, that "missing feature" is "by design" so it doesn't overheat. Macbooks are built to raidiate heat through the keyboard and if you have it powered on while closed this prevents heat from escaping. There have been confirmations of this heat up with the recent release of 10.4.7... in some cases, the macbook failed to go into sleep mode. The user found the laptop later extremely hot to the touch: :"The computer was so hot I was barely able to ouch it to do a forced restart". -- <a class="user" href="http://www.macintouch.com/readerreports/safetyissues/topic4346.html">http://www.macintouch.com/readerreports/safetyissues/topic4346.html</a>

For your information, if you plug your macbook to an external screen with an external keyboard / mouse, you'll be able to close the lid and it won't sleep. This is called clamshell mode. Granted, you need a hack to make this work with the iBook. But for the macbook and macbook pro, it is an advertised feature.

I remember a few years ago on the screensavers, someone wrote in with a PowerBook asking how to prevent it from sleeping when shut. Kevin Rose pointed to a little app which solved the problem however that app has since been discontinued and was never ported to work with Intel Macs.So, finally. Been looking for this for a long time, and it's a universal binary! Hooray.

While handbrake was doing and encode it interrupted the sleep when I closed my lid and it ran for 4 hours and it wasn't any hotter than it normally would be. I think this would only be a problem if left on an intense task for a long time.

Apple specifically suggests running macbook pros with the lid closed as perfectly viable option. There is a huge opening for ventilation on the rear edge of my older (July 2007) MacBook Pro which does the same job whether the lid is open or closed.
