The revolutionary new Gatekeeper feature makes downloading software from the Internet safer by giving you control over which apps can be installed on your Mac. You can choose to install apps from anywhere, just as you do today, or for maximum security you can set Gatekeeper to allow only apps from the Mac App Store. The default setting allows you to install apps from the Mac App Store and apps from developers that have a unique Developer ID from Apple. In addition to checking daily for security updates, Mountain Lion includes app sandboxing to keep misbehaving apps from compromising your system, and kernel ASLR for improved protection against buffer overflow attacks.

Additional new features in Mountain Lion include:

• AirPlay Mirroring, an easy way to wirelessly send an up-to-1080p secure stream of what’s on your Mac to an HDTV using Apple TV®, or send audio to a receiver or speakers that use AirPlay;

• Game Center, which brings the popular social gaming network from iOS to the Mac so you can enjoy live, multiplayer games with friends whether they’re on a Mac, iPhone, iPad or iPod touch;

• a faster Safari® with a unified Smart Search Field, iCloud Tabs that present your open tabs across your devices, and a new Tab View to quickly swipe through them;

• new features for China, including significantly improved text input, a new Chinese Dictionary, easy setup with popular email providers, Baidu search in Safari, built-in sharing to Sina Weibo and popular video websites Youku and Tudou; and

• over 1,700 new APIs that give developers access to the latest core OS and web technologies, as well as the newest features of OS X, including Documents in the Cloud, Notifications, Sharing and Game Center.
