Review of Power Nap on OS X, does it really work?

Power Nap was one of the features that finally came to OS X Mountain Lion that we didn’t notice even though it’s there, because that’s precisely what it’s all about, that we don’t notice everything that happens on our Mac while it’s on hold. In this screencast we’ve prepared we’re going to take a look at the features that Power Nap offers and some examples so we can see how it works.

With the arrival of OS X Mountain Lion a new feature was introduced in “the world’s most advanced computer operating system”, this new feature is called Power Nap and serves to have updated our Mac even having it in suspension. Power Nap is battery operated or powered and its features vary depending on whether the latter is fulfilled or not. With Power Nap battery power, it updates installed apps , email, photos, notes, reminders, and other iCloud services. And if we have the MagSafe Power Cable connected, our Mac will update Time Machine backups and download operating system updates if there is a minor update.

All of this and we won’t know what’s going on as the fans won’t turn on and we won’t have any signal, but we in this screencast are going to test this new feature: we’re going to see if it updates the mail with the battery power and if it backs up Time Machine with the power cord connected.

In the video we can see how Power Nap works quite well, I haven’t been able to do more tests because I don’t have an iCloud account but the operation is similar for all Apple’s cloud services.

The only drawback to Power Nap is that it is only compatible with some Mac models, specifically the models below:

  • MacBook Air (Mid 2012)
  • MacBook Air (Mid 2011)
  • MacBook Air (Late 2010)
  • MacBook Pro with Retina Display (Mid 2012)
