Apple: About Power Nap
Last week, Apple published a support document that provides more details on Power Nap, the technology Apple introduced with OS X Mountain Lion to manage certain updates even when a Mac is asleep.
Firstly, Apple notes that, aside from the features explained on the OS X webpage and the System Preferences app, Power Nap also supports Spotlight Indexing and Help Center updates when a Mac is plugged into an AC outlet. The “other iCloud updates” mentioned in Power Nap’s settings include Find My Mac, so you’ll be able to track a Mac’s location even with its lid closed; VPN connections (with certificates) for corporate email and configuration profile updates are supported as well.
Power Nap can be rather confusing for new users, as all of its capabilities aren’t fully explained in System Preferences and the Help Center. Apple’s document also details the frequency of Power Nap updates, so make sure to check it out here. [via @applespotlight]
