OS X Yosemite

All Macintosh computers capable of running OS X Mountain Lion (v10.8.x) are able to run Yosemite as the two operating systems have the same requirements.{{cite web|title=PSA: The iDevices and Macs that will support iOS 8 and OS X 10.10|url=https://arstechnica.com/apple/2014/06/psa-the-idevices-and-macs-that-will-support-ios-8-and-os-x-10-10|website=Ars Technica|date=June 2, 2014|access-date=June 3, 2014|url-status=live|archive-url=https://web.archive.org/web/20140603151731/http://arstechnica.com/apple/2014/06/psa-the-idevices-and-macs-that-will-support-ios-8-and-os-x-10-10|archive-date=June 3, 2014|df=mdy-all}} However, to take full advantage of the Handoff feature, additional minimum system requirements include a Mac with Bluetooth LE (Bluetooth 4.0). As with Mavericks and Mountain Lion, 2{{nbsp}}GB of RAM, 8{{nbsp}}GB of available storage, and Mac OS X Snow Leopard 10.6.8 or later are required.

These are the models that are compatible with OS X Yosemite:

• iMac (Mid 2007 to Mid 2015)
• MacBook (Late 2008 to Mid 2010)
• 12-inch MacBook (2015)
• MacBook Air (Late 2008 to Early 2015)
• MacBook Pro (Mid 2007 to Mid 2015)
• Mac Mini (Early 2009 to Late 2014)
• Mac Pro (Early 2008 to Late 2013)
• Xserve (Early 2009)

These are the models that support new features such as Handoff, Instant Hotspot as well as AirDrop between Mac computers and iOS devices:{{cite web|title=OS X Yosemite: supported devices for Handoff, Instant Hotspot, Phone Calling, SMS, and AirDrop|url=http://support.apple.com/kb/PH18947|website=Apple|access-date=December 6, 2014|url-status=live|archive-url=https://web.archive.org/web/20141210161905/http://support.apple.com/kb/PH18947|archive-date=December 10, 2014|df=mdy-all}}

• Mac Pro (Late 2013)

The default desktop wallpaper is an image of Half Dome.

Yosemite introduced a major overhaul of OS X's user interface, emphasizing flat graphic design over skeuomorphism, following the aesthetic introduced with iOS 7 and certain applications from OS X Mavericks. It is the first major redesign of the OS X user interface since 10.5 Leopard. Other changes include thinner fonts and blurred translucency effects. Some icons have been changed to correspond with those of iOS 7 and iOS 8. Yosemite maintains the OS X desktop metaphor.{{cite web|url=https://www.apple.com/osx/design|title=OS X Yosemite – Design|publisher=Apple Inc.|url-status=live|archive-url=https://web.archive.org/web/20150103104707/http://www.apple.com/osx/design|archive-date=January 3, 2015|df=mdy-all}}

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.{{cite web|title=OS X Yosemite unveiled at WWDC, features big UI overhaul|url=https://arstechnica.com/apple/2014/06/os-x-yosemite-is-coming-and-it-will-redesign-the-entire-mac-desktop|website=Ars Technica|date=June 2, 2014|access-date=June 3, 2014|url-status=live|archive-url=https://web.archive.org/web/20140603214032/http://arstechnica.com/apple/2014/06/os-x-yosemite-is-coming-and-it-will-redesign-the-entire-mac-desktop|archive-date=June 3, 2014|df=mdy-all}}{{cite web|title=Apple Changes OS X's Main Font For The First Time Ever|url=http://www.fastcodesign.com/3031354/apple-changes-os-xs-main-font-for-the-first-time-ever|website=Fast Co Design|date=June 2, 2014|access-date=June 3, 2014|archive-url=https://web.archive.org/web/20141016054429/http://www.fastcodesign.com/3031354/apple-changes-os-xs-main-font-for-the-first-time-ever|archive-date=October 16, 2014}} Yosemite is 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. In Yosemite, the Dock is a 2D translucent rectangular strip 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.

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 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 using their iPhone as a conduit, 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.{{cite web|url=https://www.apple.com/osx/continuity|title=OS X Yosemite – Mac + iOS Continuity|publisher=Apple|access-date=November 16, 2014|url-status=live|archive-url=https://web.archive.org/web/20141111005128/http://www.apple.com/osx/continuity|archive-date=November 11, 2014|df=mdy-all}}

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. The widgets in the Today view are similar to those of iOS 8.

As of OS X 10.10.3, Photos replaces both iPhoto and Aperture.{{cite news|url=https://www.theguardian.com/technology/2015/apr/16/upgrading-from-iphoto-aperture-apples-photos-read-this|date=16 April 2015|access-date=27 July 2017|first=Samuel|last=Gibbs|newspaper=The Guardian|location=London|title=Upgrading from iPhoto or Aperture to Apple's Photos?

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.{{cite web|title=OS X Yosemite: Apple's latest desktop OS works even better with your iPhone|url=https://www.engadget.com/2014/06/02/os-x-apple-yosemite|website=Engadget|date=June 2, 2014 |access-date=June 3, 2014|url-status=live|archive-url=https://web.archive.org/web/20140603044029/http://www.engadget.com/2014/06/02/os-x-apple-yosemite|archive-date=June 3, 2014|df=mdy-all}} Stock applications such as Safari and Mail have been updated.{{cite web|title=OS X Yosemite revealed: Translucent windows, cross-platform Continuity, and HTML 5 DRM come to the Mac|url=http://www.extremetech.com/computing/183438-os-x-yosemite-revealed-translucent-windows-cross-platform-continuity-and-html-5-drm-come-to-the-mac|website=ExtremeTech|access-date=June 3, 2014|url-status=live|archive-url=https://web.archive.org/web/20140603225640/http://www.extremetech.com/computing/183438-os-x-yosemite-revealed-translucent-windows-cross-platform-continuity-and-html-5-drm-come-to-the-mac|archive-date=June 3, 2014|df=mdy-all}} In particular, many security features have been added to Safari, such as a custom history clearing option that lets users clear history, cookies, and other data from the previous hour, day, or two days.

The green "zoom" button on windows now has a different function in applications that support full-screen mode. 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 Mac OS X Lion. However, holding the Option key (⌥) while clicking the zoom button or double-clicking on the window chrome continues to invoke the original behavior.{{cite web|url=http://devstreaming.apple.com/videos/wwdc/2014/209xxbyg01mfqt8/209/209_adapting_your_app_to_the_new_ui_of_os_x_yosemite.pdf|title=Adapting your app to the new UI of OS X Yosemite|publisher=Apple Inc.|date=June 3, 2014|access-date=August 10, 2014|url-status=live|archive-url=https://web.archive.org/web/20140728222435/http://devstreaming.apple.com/videos/wwdc/2014/209xxbyg01mfqt8/209/209_adapting_your_app_to_the_new_ui_of_os_x_yosemite.pdf|archive-date=July 28, 2014|df=mdy-all}}{{rp|123–124}}

On release, Yosemite received positive reviews, with users praising the simplified user interface. Programmer John Siracusa, who had reviewed every OS release, wrote for Ars Technica that "Yosemite is an aesthetic one-way valve... switching back to Mavericks after a week or two in Yosemite is like returning to iOS 6. Everything looks embarrassingly chunky, glossy, and gaudy."{{cite web|last1=Siracusa|first1=John|title=Yosemite review|url=https://arstechnica.com/apple/2014/10/os-x-10-10/25|url-status=live|archive-url=https://web.archive.org/web/20170708072022/https://arstechnica.com/apple/2014/10/os-x-10-10/25|archive-date=July 8, 2017|website=Ars Technica|date=October 16, 2014|df=mdy-all}} Macworld{{'}}s review generally praised Yosemite for its design, but noted that it had found WiFi network issues and that Continuity had proved unreliable.{{cite web|last1=Haslam|first1=Karen|title=Yosemite review|url=http://www.macworld.co.uk/review/mac-software/mac-os-x-yosemite-review-3516686|url-status=live|archive-url=https://web.archive.org/web/20150819061536/http://www.macworld.co.uk/review/mac-software/mac-os-x-yosemite-review-3516686|archive-date=August 19, 2015|access-date=August 15, 2015|website=Macworld|df=mdy-all}}
