Apple has released a developer preview of its OS X Mountain Lion.
The latest update for Mac is Apple’s ninth release of the operating system, and brings popular apps and features from the iPad to the Mac.
Mountain Lion introduces Messages, Notes, Reminders and Game Center to the Mac, as well as Notification Center, Share Sheets, Twitter integration and AirPlay Mirroring. Mountain Lion is also integrated with iCloud.
A new security feature has also been introduced called Gatekeeper, which helps users keep safe from malicious software by giving complete control over what apps are installed on the Mac.
“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,” said Philip Schiller, Apple’s senior vice president of Worldwide Marketing.
The preview release of Mountain Lion is now available to Mac Developer Program members, and Mac users will be able to upgrade to Mountain Lion from the Mac App Store in the summer.
Some of the features of Mountain Lion include:
- A new Messages app, which replaces iChat and allows users to send unlimited messages, high-quality photos and videos directly from the Mac to another Mac or iOS device.
- Game Center, which lets users personalise their Mac gaming experience, find new games and challenge friends to play live multiplayer games, whether they’re on a Mac, iPhone, iPad or iPod touch.
- A new Notification Center, which provides easy access to alerts from Mail, Calendar, Messages, Reminders, system updates and third party apps. System-wide Share Sheets make it easy to share links, photos and videos directly from Apple and third party apps.
- Twitter is integrated throughout Mountain Lion so users can sign on once and tweet directly from Safari, Quick Look, Photo Booth, Preview and third party apps.
- AirPlay Mirroring is introduced in Mountain Lion, which provides an easy way to wirelessly send a secure 720p video stream of what is on your Mac to an HDTV using Apple TV.
- Mountain Lion integrates iCloud. Mountain Lion uses your Apple ID to automatically set up Contacts, Mail, Calendar, Messages, FaceTime and Find My Mac. The new iCloud Documents pushes any changes to all your devices so documents are always up to date, and a new API helps developers make document-based apps work with iCloud.
- Mountain Lion also has features specifically designed to support Chinese users, including significant enhancements to the Chinese input method and the option to select Baidu search in Safari.
