June 2, 2014: Apple shows off OS X 10.10 Yosemite for the first time at its Worldwide Developers Conference. Following the Jony Ive-redesigned iOS 7, Yosemite boasts an aesthetic change that brings Apple’s desktop computers closer than ever to the look of the company’s mobile software.
Named after Yosemite National Park, the update follows the previous year’s Mavericks as the second Mac operating system named after a famous California landmark.
