OS X 10.9 Mavericks review: Different name, looks the same
Apples new desktop/laptop OS builds on its predecessors, applying polish where needed.
OS X 10.9, better known as Mavericks, is the 10th iteration of the operating system that powers Apple’s desktops and laptops. Unlike previous versions, Mavericks is the first to be named after a place in California instead of a large cat — and the first to be given away by Apple for free. Even so, it still looks and acts very much like its predecessor, Mountain Lion, meaning there’s no major learning curve for users who upgrade.
