Apple OS X 10.10 is expected to be announced at the WWDC.

The computer operating system upgrade, which goes by the internal codename “Syrah,” has been dubbed OS X “Yosemite” as its official marketing name.

The OS X 10.10 operating system is expected to largely focus on updates to the user-interface design. In particular, OS X 10.10 may adopt a look and feel similar to Apple’s iOS 7 mobile operating system. OS X 10.10 may feature app icons that look like those on iOS 7 in addition to an overall “glassy” and “flat” feel, with apps and programs opening directly on top of the desktop with no shadowing.  The update may also include a new design for the Mac App Store and new version of iWork and iLife.
