Power Nap

[Tegeril]

I remember seeing the screenshots showing a 'use power nap on battery' checkbox or something to that effect. I now have Mountain Lion on my rMBP (did a wipe and reinstall) and don't see that option. Did that change from one of the dev previews?

When I search "Power Nap" in System Preferences, it directs me to the Energy Saver pane but there are 0 Power Nap related settings in there.

It's kind of bizarre o.o

[edit] Seems to be an issue for others, the firmware update brought it to the Airs but... not the last commenter (at this moment) here: https://discussions.apple.com/thread/4135524?start=0&tstart=0

isnt there a wake for wifi option under Energy Saver? I thought that was power nap, might be wrong tough

This is what I see running OS X 10.8 (12A269) on a 2011 MacBook Air. Note the "Enable Power Nap while on battery power" option.

My late 2008 MacBook Pro doesn't get any of the fancy features.

Power Nap requires a Mac notebook with built-in flash storage. May require a firmware update

I know on my 2011 Air, I had a firmware update that added the feature.

The firmware for the retina MacBook Pro hasn't been released yet. So right now it's only working for 2011 and 2012 MacBook Airs.
