I have turned off computer sleep on my Late 2012 iMac. It is set to “Never.” I do have my screen set to go to sleep. I have an add-on called Caffeine which, when selecting with my mouse, will allow me to either keep the display on or allow it to go to sleep. It’s my understanding that OS X runs its utilities during the wee morning hours and I don’t want to interfere with that (I could be wrong).
