OS X Yosemite

OS X Yosemite, or OS X 10.10, is the eleventh major release of the OS X operating system released on 16 October 2014. This version includes major interface overhauls, replacing the older, skeumorphic icons with newer, flat ones that resembled the designs on iOS 7. The old default font (Lucida Grande) was changed to Helvetica, until OS X El Capitan, where it was changed again to San Francisco.
