Update: Check out our OS X Mountain Lion review.

Apple has made its “most advanced” desktop operating system, OS X Mountain Lion, available for download.

Users are now able to upgrade their old Lion or Snow Leopard systems with the new OS, so long as they have the required 2GB of memory and 8GB of available space needed to facilitate it.

Apple says that Facebook integration will be available in an upcoming software update, however, the company failed to mention when it will be rolled out.

New features in Mountain Lion include Gatekeeper, which makes downloading software from the Internet safer; Power Nap, which automatically updates your apps and system while your Mac is asleep; and a faster Safari browser.

Apple OS X Mountain Lion: Features

Utilising the multi-touch trackpad on the MacBook Pro the new OS X lets you swipe across the homescreen, moving the wallpaper to one side revealing the Notification Bar.

Also included is Messages, a Mac specific version of the iMessage app found on iPod Touch, iPhone and iPad and lets you talk for free to anyone on those devices from a Mac, or indeed from a Mac to a Mac.

Elsewhere there has been increased integration between social media and core applications including direct Twitter buttons for Safari and other apps.

Finally, Gatekeeper is a new security feature that allows you to restrict where you download apps and files from giving you more control over what is sent to your iMac or MacBook.
