OS X Yosemite
The upcoming eleventh major release of OS X, Apple Inc.’s desktop and server operating system for Macintosh computers. OS X Yosemite was announced and released to developers on June 2, 2014 (June 3 in Japan), at WWDC 2014. Yosemite will be released to consumers in fall 2014.
Following the new naming scheme set up in OS X Mavericks, Yosemite is named after the national park in California. Prior to its launch, Yosemite was known internally as Syrah.
Yosemite introduced a major revision to the operating system’s user interface, modelled after iOS 7; the interface incorporates a flatter visual appearance with blurred translucency effects.
Other notable design changes include new icons, light and dark colour schemes, and the replacement of Lucida Grande with Helvetica Neue as the new default system font. The dock is now a 2D translucent rectangle instead of a skeuomorphic glass shelf, reminiscent of the dock design used in early versions of OS X.
