Apple announces OS X Mavericks with Finder tabs, tags, and true multiple display support

Apple on Monday unveiled Mavericks, the start of the next 10 years of its Mac OS X operating system, with a naming switch from breeds of cat to California locales. It will launch this fall on the Mac App Store

Craig Federighi, head of OS X development for Apple, unveiled OS X 10.9 Mountain Lion at the Worldwide Developers Conference 2013 keynote. He highlighted three key features found in the forthcoming operating system update: new tabs in Finder, the ability to tag individual files, and enhanced support for multiple displays.

In one example, Federighi labeled a file with multiple tags such as "Important," "In Review," and "Website." On the left side of Finder, color-coded tags are viewable, allowing users to more quickly locate files associated with each tag.
