The arrival of Lion (10.7), though, marked a full upgrade. With features like Launchpad and Mission Control, it seemed like it might be the last version Cupertino dropped before finally pulling the trigger on operating system number 11, and perhaps transitioning to something with an even stronger iOS influence. Right now, at least, the company’s not ready to close the book on chapter X, but it is giving the world a first peek at 10.8. Ladies and gentlemen, meet Mountain Lion.

The ninth major release of the world’s most advanced operating system, which brings popular apps and features from iPad® to the Mac® and accelerates the pace of OS X innovation. 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 the first OS X release built with iCloud® in mind for easy setup and integration with apps. The developer preview of Mountain Lion also introduces Gatekeeper, a revolutionary security feature that helps keep you safe from malicious software by giving you complete control over what apps are installed on your Mac. The preview release of Mountain Lion is available to Mac Developer Program members starting today. Mac users will be able to upgrade to Mountain Lion from the Mac App Store™ in late summer 2012.

Well,  iOS has practically moved in to Mac’s house. If Lion was a toothbrush in the bathroom, Mountain Lion is a chest of drawers in the bedroom. Reminders, iMessage, Game Center, Notifications, iCloud and Twitter integration — all iOS’s most intimate stuff is here, and it all pretty much looks the same as it does on the iPad. Most of it is designed to sync up so it is exactly the same.


Gatekeeper is a revolutionary new security feature that gives you control over which apps can be downloaded and installed on your Mac. You can choose to install apps from any source, just as you do on a Mac today, or you can use the safer default setting to install apps from the Mac App Store, along with apps from developers that have a unique Developer ID from Apple. For maximum security, you can set Gatekeeper to only allow apps from the Mac App Store to be downloaded and installed.

Chinese users:

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. Mountain Lion makes it easy to set up Contacts, Mail and Calendar with top email service providers QQ, 126 and 163. Chinese users can also upload video via Share Sheets directly to leading video websites Youku and Tudou, and system-wide support for Sina weibo makes microblogging easy.
