How to prevent a MacBook (the system, not the screen) from going to sleep?
I want the screen to go to sleep (which I realise is set in System Preferences -> Energy Saver) but I want the rest of the system to stay active, so that background processes I have running will continue. I can't seem to find how to set when the system goes sleep.
MacBook Pro with Retina display, OS X Mavericks (10.9)
