Yosemite deep-dive review:
OS X 10.10, otherwise known as Yosemite, is the 11th iteration of the operating system that powers the desktops and laptops created by Apple. This update marks the second version of OS X whose code name is based on a California location instead of a species of cat — and the second time Apple has let loose a major update for free. The design focus in Yosemite, according to Apple, was to bring better focus on content.
