Apple's newest Macs will be able to accomplish updates, data refreshes, and more -- all while the computers are asleep.
At its Worldwide Developers Conference in San Francisco today, Apple unveiled a feature called Power Nap. Available on second-generation MacBook Airs and MacBook Pros with Retina Displays, Power Nap is all about keeping Macs up to date even while they're snoozing.
The computers will be able to fetch data while in sleep mode, do an iCloud sync, update system software, get e-mail, and even do a Time Machine backup.
This could be a very useful feature for heavy users who put their computers to sleep when not in use but are likely to have a variety of data coming in during that time.
