One of OS X Mountain Lion's lesser-known features is the curiously named Power Nap. It's roughly analogous to an actual sleeping mountain lion; while he's catching some Zs in a tree, his brain is constantly aware of what's going on around him, monitoring sounds and scents that might spell danger or food. Likewise, Mountain Lion's Power Nap will keep your Mac a tiny bit awake. Just enough of the system will be active during sleep (on certain Mac models) to grab email, notes, reminders and messages, run backups, and download OS X updates. All of this is done without turning on a screen, powering up a fan, or doing anything else that could appear to be "waking" your Mac. It's enabled for both plugged-in and battery-only setups by checking the appropriate Power Nap box on System Preferences > Energy Saver. Power Nap in OS X Mountain Lion works only on current MacBooks that only ship with built-in flash storage -- the MacBook Air (2nd generation, meaning 2011 or later) and Retina MacBook Pro -- so this isn't a feature you're going to see on every Mac today. Will we see this extending to more Macs in the future? I certainly hope so; it could theoretically work on any Mac with proper power management circuitry and a boot SSD. I've enabled it on my 2011 MacBook Air and it works quite well. Previously, if I hadn't awakened the MBA for several days, I could count on having the Mail app spin for quite a while as it downloaded my email. Now when I open my Air's cover, I can be sure that it's going to be up to date with most, if not all, of my email. #next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; } Continue reading Mountain Lion 101: Power NapMountain Lion 101: Power Nap originally appeared on TUAW - The Unofficial Apple Weblog on Wed, 25 Jul 2012 14:00:00 EST.

Mountain Lion-Mac App Store-Power Nap-Apple
At today's WWDC keynote event, Apple announced a release timeframe and pricing for Mountain Lion, the next version of the Mac operating system which was previewed earlier this year. Executives also gave a preview of some new features including dictation, iCloud Tabs, and Power Nap. Mountain Lion will be released in July through the Mac App Store for $19.99 and all Macs purchased starting today can receive an upgrade for free.
The new dictation feature will be integrated throughout the operating system to allow dictation anywhere to enter text. Dictation was previously rumored in May when resource files in Safari listed keyboard shortcuts that pointed to dictation functions.
iCloud Tabs, a new feature in Safari on the Mac, was also demonstrated. iCloud Tabs will show all tabs open in Safari on all other iOS devices and Macs logged in to the same iCloud account. Safari also gains a unified search and address bar to streamline its interface.
Power Nap is a new feature that will carry out functions while a Mac is charging and sleeping. New emails will be downloaded, Time Machine will automatically run, app updates will be applied and other actions will be carried out with Power Nap, which will be available on the new ultra-thin MacBook Pro that was announced today and second-generation and later MacBook Airs.
Apple first previewed Mountain Lion in February, highlighting many features already present in iOS, including Messages, Reminders, Notes, Notification Center, Game Center and more at that time. read more..
