Hello folks
I've just encountered this new layout for the Energy Saver pref pane on a late 2013 27" iMac.
I'm guessing you just check the box that says 'Prevent computer from sleeping automatically when the display is off', if you don't want it to ever go to sleep. Presumably then the Haswell chip's power management keeps it just barely ticking over.
I checked just the box for that, and also for:
Hard disks to sleep
Wake for network.
-This is on an iMac I need to be able to access through the network at any time.
-Below is the output from pmset -g with the above settings in place, if anyone's interested:
