Thanks to a third party kernel extension called NoSleep we can now remove those hardware limitations and run a Mac laptop with the lid closed and no hardware attached.</p> <p>Installing NoSleep is easy and places a System Preference panel for configuration, along with a menu bar item that lets you toggle the NoSleep function similar to the Caffeine app, but only impacting lid sleep behavior. </p> <ul> <li><a href="http://code.google.com/p/macosx-nosleep-extension/">Download NoSleep from Google Code</a></li> </ul> <p><img src="http://osxdaily.com/wp-content/uploads/2012/02/closed-macbook-no-sleep.jpg" alt="Closed MacBook No Sleep" title="closed-macbook-no-sleep" width="620" height="388" class="aligncenter size-full wp-image-27070" /></p> <p>Check “Do not fall asleep when lid is closed” and you can freely shut a portable Mac without the machine sleeping, even without a keyboard or display attached. This is great if you have an old MacBook laying around you want to use as a file server or wireless <a href="http://osxdaily.com/2010/06/18/mac-media-center/">media center</a>, or you just want to close a Mac while it sits quietly on a desk downloading large files or anything else – just remember to keep the Mac well ventilated when running with the lid closed.</p> <p>If you’re done with NoSleep or just don’t find it useful, uninstalling NoSleep is best achieved through the bundled uninstaller bash script.</p> <p>This extension was found on Twitter, although I can’t recall who from or the origin tweet. Thanks to whoever it was!</p> </div> <p><a href="http://feedads.g.doubleclick.net/~a/3v68CEwVHffdxwcMRdo5rYI6uJ0/0/da"><img src="http://feedads.g.doubleclick.net/~a/3v68CEwVHffdxwcMRdo5rYI6uJ0/0/di" border="0" ismap="true"></img></a><br/> <a href="http://feedads.g.doubleclick.net/~a/3v68CEwVHffdxwcMRdo5rYI6uJ0/1/da"><img src="http://feedads.g.doubleclick.net/~a/3v68CEwVHffdxwcMRdo5rYI6uJ0/1/di" border="0" ismap="true"></img></a></p><div class="feedflare"> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=8sEuwJBbE1I:hHGXNHB7FLY:yIl2AUoC8zA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=yIl2AUoC8zA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=8sEuwJBbE1I:hHGXNHB7FLY:V_sGLiPBpWU"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=8sEuwJBbE1I:hHGXNHB7FLY:V_sGLiPBpWU" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=8sEuwJBbE1I:hHGXNHB7FLY:D7DqB2pKExk"><img src="http://feeds.feedburner.com/~ff/osxdaily?i=8sEuwJBbE1I:hHGXNHB7FLY:D7DqB2pKExk" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=8sEuwJBbE1I:hHGXNHB7FLY:7Q72WNTAKBA"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=7Q72WNTAKBA" border="0"></img></a> <a href="http://feeds.feedburner.com/~ff/osxdaily?a=8sEuwJBbE1I:hHGXNHB7FLY:qj6IDK7rITs"><img src="http://feeds.feedburner.com/~ff/osxdaily?d=qj6IDK7rITs" border="0"></img></a> </div><img src="http://feeds.feedburner.com/~r/osxdaily/~4/8sEuwJBbE1I" height="1" width="1"/> View the full article
