Is there any way to set a MacBook Pro to not sleep when you close the lid?

I have a Macbook Pro (early 2011) with Mountain Lion installed.

Is there a way to prevent my Mac from going to sleep even on lid close?

If you have an external monitor plugged in, it will happen automatically.

Otherwise, you can use InsomniaX.

    cmdline equivalent is: caffeinate since pmset noidle is deprecated in favor of caffeinate (https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/pmset.1.html) – dza Jul 05 '15 at 17:25

    Note also that InsomniaX is no more supported on recent version os OSX. See here for alternatives. – рüффп Oct 24 '20 at 07:33
