Apple seeds OS X Mavericks Developer Preview 7

The next version of the Mac operating system, OS X 10.9, is officially labeled as OS X Mavericks. Mavericks, named after an epic surfing spot in northern California, has a lot of new features, but also represents a change in naming conventions away from the familiar cat themes. In future versions of OS X will follow the same naming convention and all be named after inspirational places throughout California, where Apple is located.
