Many of Yosemite's new features focus on the theme of 'continuity', increasing its integration with other Apple platforms and services such as iOS and iCloud.

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 through Tiger and in iOS since iOS 7. It was the only macOS version to use Helvetica Neue as the default typeface, as in El Capitan it was again changed, this time to Apple's own, newly-designed San Francisco typeface. Other design changes include new icons, light and dark color schemes, and the replacement of Lucida Grande with Helvetica Neue as the default system typeface. Yosemite maintains the OS X desktop metaphor. Some icons have been changed to correspond with those of iOS 7 and iOS 8. Other changes include thinner fonts and blurred translucency effects. It is the first major redesign of the OS X user interface since 10.5 Leopard. Yosemite introduced a major overhaul of OS X's user interface, emphasizing flat graphic design over skeuomorphism, following the aesthetic introduced with iOS 7. These are the models that support new features such as Handoff, Instant Hotspot as well as AirDrop between Mac computers and iOS devices: These are the models that are compatible with OS X Yosemite:

As with Mavericks and Mountain Lion, 2 GB of RAM, 8 GB of available storage, and Mac OS X Snow Leopard 10.6.8 or later are required. However, to take full advantage of the Handoff feature, additional minimum system requirements include a Mac with Bluetooth LE (Bluetooth 4.0).

Following the Northern California landmark-based naming scheme introduced with OS X Mavericks, Yosemite is named after the national park.Īll Macintosh products capable of running OS X Mountain Lion (v10.8.x) are able to run Yosemite as the two operating systems have the same requirements. Yosemite was released to consumers on October 16, 2014. OS X Yosemite was announced and released to developers on June 2, 2014, at WWDC 2014 and released to public beta testers on July 24, 2014.

OS X Yosemite ( / j oʊ ˈ s ɛ m ɪ t i/ yoh- SEM-it-ee version 10.10) is the eleventh major release of macOS, Apple Inc.'s desktop and server operating system for Macintosh computers.
