WWDC: Apple Unveills OS X Yosemite and iOS 8

Apple kicked off its worldwide developers conference Monday morning by talking about the newest versions of its desktop and mobile operating systems, OS X Yosemite and iOS 8.

“Our operating systems, devices and services all work together in harmony,” CEO Tim Cook said in wrapping up Monday’s address. “Together, they provide an integrated and continuous experience across all of our products.”

Cook announced that the newest version of Apple’s desktop software, OS Mavericks, is now running on more than half of Mac desktops less than a year after its introduction; Cook compared that with Windows 8, which he said is running on just 14 percent of Microsoft computers. Cook returned to that theme later, showing that 89 percent of Apple mobile devices were using the latest iOS, while only 9 percent of Android users have the newest version of Google’s mobile operating system.
