In the newest operating system, Apple OS X Mountain Lion in addition to all other new features and updates the ability to use your MacBook in a mode Power Nap. Unfortunately, not all Apple laptops support work in this mode. However, the pleasant surprise was the support MacBook Air the middle of last year, along with models of the year - MacBook Air and MacBook Pro 2012 with Retina-display.
And actually, what is the function and what it is good? With the Power Nap your laptop will be able to check email or update the photostream while in sleep mode. Agree, it's incredibly cool - you are done with a computer, a familiar gesture closed the lid, and then when the computer you are needed again, you do not have to wait to update all the programs, because they were in the background. As the number of these tasks, it is worth noting that the list has turned out quite extensive.
Contact us. The data of your contacts will be updated in the background - it is necessary to introduce new information on the iPhone or iPad, it immediately turns your MacBook.
Calendar. Updates the calendar and the new prompt, you can also get in the mode Power Nap.

Find my Mac can help you find a lost MacBook.
All of these updates will work regardless of whether the laptop is connected to power or not. However, the energy consumption in this mode is minimal and does not appreciably affect the time of the laptop from a single battery charge. If the MacBook is connected to the outlet, the Power Nap mode can operate additional services: for example, indexing Spotlight or download programs from the Mac App Store.
With regard to the update, everything is quite simple: every time your laptop will check your mail, keep track of changes in calendars and notes, and once a week will be checked the available downloads from the Mac App Store. If the laptop battery is below 30%, the Power Nap will not be used to conserve battery power and do not discharge it completely. It is recommended to disconnect all peripherals and USB-Thunderbolt-devices using Power Nap, as they may contribute to a more rapid discharge batteries.
Power Nap function can hardly be called "killer-fiche", which will force buyers to replace their computer to the new "MacBook" although on the other hand it has the potential to become one of the most overlooked features of the new OS. Even if you do not speak about the ease of software updates, notes and email, then Find my Mac, running in the background - it's just fine.
