During the last evening the Apple company published an update for Mountain Lion Developer Preview 4, but here we are only talking about a minor change implemented in the same Preview 4. The first change implemented in Mountain Lion is related to FaceBook because Apple has implemented support for Notifications Center, so now you will be warned through a notification message about almost everything that happens on your account. In the Settings menu of the Notifications Center, you have the option to choose which actions on Facebook will be displayed in the Notifications Center and how they appear.
The second change involves the implementation of the PowerNap function in certain users' Macs. Using the function powernap a Mac can update its emails, iCloud accounts plus many others when its lid is closed and theoretically it should be in sleep mode. This mode is implemented by Apple with the idea of giving users the option of having their Macs permanently updated, but keeping the battery autonomy almost intact. OS X Mountain Lion it could be launched on July 19 in the Mac App Store and will natively contain these functions for all Mac owners.
