Apple has announced OS X Mountain Lion, the next version of its Mac operating system.Mountain Lion, which is available to developers from today, takes more features and applications from the iPad and iPhone and brings them to Apple's laptop and desktop computers.
 
It will be available to users later this year according to Apple.

The new version of OS X brings iOS features such as Notification Centre, Game Centre and AirPlay mirroring will now be a part of the Mac Applications such as Notes and Reminders, which will be familiar to iPhone and iPad users are also coming to OS X.

“The developer preview of Mountain Lion comes just seven months after the incredibly successful release of Lion and sets a rapid pace of development for the world’s most advanced personal computer operating system," Phil Schiller, Apple's senior vice president of worldwide marketing, said in a statement.

The biggest new feature is Gatekeeper, which lets you control the apps that run on your Mac. With Gatekeeper turned on, your Mac will run only apps downloaded from the Mac App Store or those from elsewhere that have "a unique Developer ID from Apple".

For added security, users can choose to run only apps from the Mac App Store.

The new security features clearly nudge users towards the Mac App Store - and towards a more controlled application environment, similar to the iTunes App Store. However, Gatekeeper is optional, so users who prefer to run whatever apps they like can continue to do so.
