NoSleep for Mac OS X

NoSleep for Mac OS X is a program to prevent your MacBook from sleeping. On a MacBook Air, MacBook Pro, or Macbook with traditional clamshell mode, an external display, mouse, and keyboard must be attached in order to maintain the running closed-lid clamshell state. Thanks NoSleep we can now remove those hardware limitations and run a Mac laptop with the lid closed and no hardware attached.

The problem I was facing was that when I had a keyboard, trackpad, and external monitor attached and removed the power supply / power adapter my macbook would go to sleep.

Now thanks to NoSleep I can easily toggle the sleep mode to keep the computer awake.

This is similar to the Caffeine extension which can keep your monitor awake during presentations – it also sits in the menu bar.

    Hi. I uninstalled the NoSleep application using the Uninstall.command but whenever I turn on the computer I get this message onscreen: Oops! NoSleep kernel Extension is not loaded. It seems the Uninstall.command still left some files behind.

    How can I totally remove this program from my system?

    I have run the Uninstall.command more than once but the problem persists.
