Mac OS X Yosemite

First introduced in June at WWDC, Apple's new Mac operating system, OS X Yosemite, will be available today for free, the company announced at today's iPad event.

To begin, there's a design overhaul, but the most exciting new features are iCloud Drive, a better Safari, a new way to call people from your computer, and continuity between all your Mac devices.
