$10? There are multiple free programs that accomplish this task.

Also, there is a new terminal command for sleep prevention, it's called "caffeinate" - search for it.

Sorry for anyone wasting the $.

I've been looking for something like this for a long time to stop my Macbooks from turning off when the screen was closed!

It looks like everything works as advertised on my 2011 MBA / 10.7.3. However, I think it could be so much better with a new mode that is a mix of
"Prevent sleep with lid closed, displays will sleep"
and
"Allow sleep timer"

It would act like the first, but also specify a timer so if you forget it too long, it will eventually go to sleep. The timer would start counting when the lid was closed and never be in effect when the lid was open.

This way, I can close the computer to carry it around, but if I don't open it after a specified amount of time, it will sleep. I think a lot of people would like this mode since it keeps the computer awake (including network connections) if you're just taking the laptop around your home or office. However, it will sleep after some time in order to save battery power and prevent overheating.

An option to set a keyboard shortcut to enable / disable would be great. (like InsomniaX has).

Also, I found a usability bug in the program. I use a side dock on the left side of the screen; when first launching the program it put some windows under the dock, and in order to move or close them, I had to autohide the dock. Moving the default position for these windows further from the edge of the screen would easily solve this problem.

same as insomniaX, this app doesn't work on new mbp models of 2011.
when I close the lid, all of my mbp's go to sleep.
completely useless.
it used to work on my older mbp's, also running OSX 10.6.7.

Why not just take Caffeine for free? Works perfect with one click.

Caffeine is great - I use it in on my iMac. But if you need to operate lid-closed on a MacBook Air (Late-2010) say, and also allow its display to sleep during, then SleepLess is the only game in town AFAIK...

Why not just change the system settings? (that's what they're there for). It won't cost you anything either...

I challenge you to find a way in OS X system settings to prevent your laptop from going to sleep when you close the lid. :-) I think that's what makes this program stand out.

Consider Caffiene (http://www.macupdate.com/info.php/id/24120). Does it nice and simple and for free.

I tried Caffeine, and when it's activated my laptop still goes to sleep when I close the lid. Whereas SleepLess has an option to prevent this from happening.

DO NOT USE v.2.2.1 ON MACBOOK!!

I just spent an hour on the phone with AppleCare support, only to find out that Sleepless 2.2.1 had badly corrupted the PRAM on my Intel Core Duo MacBook. Since Sleepless claims Intel compatibility, it may be an incompatibility with Apple's recent SMC firmware update.

Only one use of this software had completely crippled my system, preventing even the most basic of firmware functionality, including the boot process. This is a bad bug. DO NOT ATTEMPT!!

I hope you have contacted the developer regarding this issue.

Yes I have contacted the developer, but have not received a response yet.

I've since done more research and determined that it probably wasn't Sleepless that was causing my problems. I've contacted the developer to apologize for implicating their software, but you can never be too careful with these things. I wanted to make sure no one else made the same mistake...

Nirsus had trouble on 26 Feb 2006
The last version of this worked wonderfully for me. But for some reason the system tries to automatically log out while sleepless is running which interrupts whatever program I want to leave running over night. This is on an iBook G4 1.33ghz with OSX 10.4.5, and leaving the lid open with the display backlight off.
