OS X Yosemite (/jˈsɛmɨt/ yoh-SEM-it-ee) (version 10.10) is 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 and beta testers on June 2, 2014, at WWDC 2014. Yosemite will be released to consumers in late 2014.[3][4] Following the new naming scheme introduced with OS X Mavericks, Yosemite is named after the national park in California.



Yosemite introduced a major revision to the operating system's user interface, designed with inspiration from iOS 7, while still maintaining the OS X look and feel that many have become accustomed to. The interface incorporates a flatter visual appearance with blurred translucency effects.

Other notable design changes include new icons, light and dark color schemes, and the replacement of Lucida Grande with Helvetica Neue as the new default system font.[5][6][7] 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.


Many of Yosemite's new features focus on the theme of "continuity", increasing its integration with other Apple services and platforms such as iOS and iCloud. The Handoff functionality allows the operating system to integrate with iOS 8 devices over Bluetooth LE and Wi-Fi; users can place and answer phone calls to and from an iPhone using their Mac as a speakerphone, send and receive text messages, activate personal hotspots, or load items being worked on in a mobile app (such as Mail drafts or Numbers spreadsheets) directly into their desktop equivalent.[8]

Notification Center[edit]

Notification Center also features a new "Today" view, also similar to that in iOS, which can display information and updates from various sources, along with widgets.[5][6] The widgets in the new today view are similar to what Apple will offer starting in iOS 8, and most function like that in iOS.

Other features[edit]

Spotlight is more tightly integrated with the operating system; it now displays its search box in the center of the screen and can include results from online sources, including Bing, Maps, and Wikipedia.[5] Stock applications such as Safari and Mail have also been updated.[9]

The green "zoom" button on windows now has a different function. Instead of simply enlarging the window, the button now enters full screen mode, eliminating the full screen button at the top right corner of windows that has been present since OS X Lion. However, holding the Option key while clicking the zoom button continues to invoke the original behavior.[10]

Beta testing[edit]

Developer Previews[edit]

As with older releases of OS X, Apple offers developer previews to developers, usually releasing a new developer preview every 2 weeks on Monday up until the release of the operating system. This is available to developers signed up for Mac Developer Program through the Mac Dev Center.

Public Beta Program[edit]

Unlike previous releases where pre-release software was just available to developers, Yosemite is part of the OS X Beta Seed Program, a public beta program which allows normal Mac users to test out new features in Yosemite. The program will only accept the first million sign-ups as can be seen by those who haven't signed-up,[11] and beta testers will be required to sign a non-disclosure agreement.[12] The program was released on July 24, 2014.[13]

System requirements[edit]

No changes in system requirements have been made for Yosemite, meaning that all Macintosh products capable of running OS X Mavericks will be supported by Yosemite; as with Mavericks, 2 GB of RAM, 8 GB of available storage, and OS X 10.6.8 (Snow Leopard) or later are required.[14]
