OS X Yosemite (/joʊˈsɛm[invalid input: 'ɨ']tiː/ 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 on June 2, 2014, at the WWDC 2014 and it was released to public beta testers on July 24, 2014. Yosemite is scheduled for final release to consumers in the northern autumn of 2014 (spring in the Southern Hemisphere).[4] Following the California landmark-based naming scheme introduced with OS X Mavericks, Yosemite is named after the national park.

Features

Design

Yosemite introduced a major revision to the operating system's user interface, designed with inspiration from iOS 7, while still maintaining the OS X desktop metaphor. 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 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 up to Tiger.

Continuity

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.

Notification Center

Notification Center features a new "Today" view, similar to that in iOS. The Today view can display information and updates from various sources, along with widgets.[5][6] The widgets in the Today view are similar to those of iOS 8.

Other

Spotlight is a more prominent part of 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 been updated.[8]

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.[9]: 123–124 

JavaScript for Automation (JXA) is the new system-wide support for scripting with JavaScript, built upon JavaScriptCore and JavaScript OSA.[10] It features an Objective-C bridge which enables entire Cocoa applications to be programmed in JavaScript.[11]

Beta testing

Apple has initiated a new public beta program for OS X, a practice not seen with its operating systems since 2000's US$29.95 Mac OS X Public Beta which had preceded the release of Mac OS X v10.0. Yosemite is part of the OS X Beta Seed Program, a public program which allows the first 1 million[12] users to download and test the Yosemite beta at no charge. Beta testers are required to acknowledge the potential risks involved with prerelease software, and sign a non-disclosure agreement (NDA).[13] The program began releasing Public Betas on July 24, 2014.[14] Currently there have been five public betas released.

As with previous releases of OS X, Apple offers preview releases to developers, usually every two weeks on Monday until the final retail release. This is available to developers signed up for Mac Developer Program through the Mac Dev Center (although those who signed up for an iOS Dev program will get one copy of Yosemite at no charge).

System requirements

All Macintosh products capable of running OS X Mavericks are 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.[15] However, the system requirements in order to take full advantage of the features in Continuity include a Mac with Bluetooth LE (Bluetooth 4.0).

These are the models compatible with OS X Yosemite:

  • iMac (Mid 2007 or later)
  • MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
  • MacBook Pro (13-inch, Mid-2009 or later), (15-inch, Mid/Late 2007 or later), (17-inch, Late 2007 or later)
  • MacBook Air (Late 2008 or later)
  • Mac Mini (Early 2009 or later)
  • Mac Pro (Early 2008 or later)
  • Xserve (Early 2009)

These are the models that have Bluetooth LE support:
