OS X Yosemite (/joʊˈsɛmɪti/yoh-SEM-it-ee; version 10.10) is the eleventhmajor release ofmacOS,Apple's desktop andserver operating system forMacintosh computers.
OS X Yosemite was announced and released to developers on June 2, 2014, atWWDC 2014 and released to public beta testers on July 24, 2014. Yosemite was released to consumers on October 16, 2014.[4] Following theNorthern California landmark-based naming scheme introduced withOS X Mavericks, Yosemite is named after thenational park.
All Macintosh computers capable of runningOS X Mountain Lion (v10.8.x) are able to run Yosemite as the two operating systems have the same requirements.[5] However, to take full advantage of theHandoff feature, additional minimum system requirements include a Mac withBluetooth LE (Bluetooth 4.0). 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.
These are the models that are compatible with OS X Yosemite:
These are the models that support new features such as Handoff, Instant Hotspot as well asAirDrop between Mac computers andiOS devices:[6]
The defaultdesktop wallpaper is an image ofHalf Dome.
Yosemite introduced a major overhaul of OS X'suser interface, emphasizingflat graphic design overskeuomorphism, following the aesthetic introduced withiOS 7 and certain applications fromOS X Mavericks. It is the first major redesign of the OS X user interface since10.5 Leopard. Other changes include thinner fonts and blurred translucency effects. Some icons have been changed to correspond with those of iOS 7 andiOS 8. Yosemite maintains theOS Xdesktop metaphor.[7]
Other design changes include new icons, light and dark color schemes, and the replacement ofLucida Grande withHelvetica Neue as the default system typeface.[8][9][10] 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-designedSan Francisco typeface. In Yosemite, theDock is a 2D translucent rectangular strip instead of a skeuomorphic glass shelf, reminiscent of the Dock design used in early versions of OS X throughTiger 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 asiOS andiCloud.[11] The Handoff functionality allows the operating system to integrate withiOS 8 devices overBluetooth LE andWi-Fi; users can place and answer phone calls using theiriPhone as a conduit, send and receivetext messages, activatepersonal hotspots, or load items being worked on in amobile app (such asMail drafts orNumbersspreadsheets) directly into their desktop equivalent.[11]
Notification Center features a new "Today" view, similar to that iniOS. The Today view can display information and updates from various sources, along withwidgets.[8][9] The widgets in the Today view are similar to those ofiOS 8.
As of OS X 10.10.3,Photos replaces bothiPhoto andAperture.[12] It uses iCloud Photo Library to upload all the user's photos across their devices.
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, includingBing,Maps, andWikipedia.[8] Stock applications such asSafari andMail have been updated.[13] 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. In addition, Apple addedDuckDuckGo to its search offerings, a non-tracking search engine that doesn’t store users’ data.[14] Safari allows you to remotely close tabs from an iOS device.[15]Safari now supports browsing in private browsing mode with certain windows (as opposed to all the windows having to be either in or out of private browsing).[16]
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 sinceMac OS X Lion. However, holding theOption key (⌥) while clicking the zoom button or double-clicking on the window chrome continues to invoke the original behavior.[17]: 123–124
JavaScript for Automation (JXA) is the new system-wide support for scripting withJavaScript, built uponJavaScriptCore and theOpen Scripting Architecture.[18] It features anObjective-C bridge which enables entireCocoa applications to be programmed in JavaScript.[19]
Along with other framework changes,CloudKit was integrated in this release.[20] CloudKit functions as aMobile Backend as a Service (MBaaS) and is one method forapp developers to integrate access to Apple’s iCloudservers into their apps.[21]
There is a "dark mode" inSystem Preferences which makes the Dock and menu bar darker.[15]
Apple initiated a new public beta program for OS X, a practice not seen with its operating systems since 2000'sUS$29.95Mac OS X Public Beta, which had preceded the release ofMac OS X v10.0. Yosemite is part of the OS X Beta Seed Program, a public program that allows the first 1 million[22] 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 anon-disclosure agreement (NDA).[23] The program began releasing Public Betas on July 24, 2014.[24] Six public betas of Yosemite were released.
On release, Yosemite received positive reviews, with users praising the simplified user interface. Programmer John Siracusa, who had reviewed every OS release, wrote forArs Technica that "Yosemite is an aesthetic one-way valve... switching back toMavericks after a week or two in Yosemite is like returning toiOS 6. Everything looks embarrassingly chunky, glossy, and gaudy."[25]Macworld's review generally praised Yosemite for its design, but noted that it had found WiFi network issues and that Continuity had proved unreliable.[26]
Yosemite faced problems with network stability and thediscoveryd DNS program. Because of this, Apple replaceddiscoveryd with themDNSResponder system (used in Mavericks) in 10.10.4.[27] Another notable bug experienced on Yosemite was the 'Unicode of death' problem, following a similar bug in 2013, in which a meaningless Arabic text string could crash applications using the system text-display APIs.[28] Some users who upgraded to Yosemite complained that the Finder fails to show the contents of folders.[29]
Spotlight on Yosemite by default reports the user's current location (at the city level) and all their search queries to Apple and third parties.[30][31][32][33] Reporting by Spotlight can be disabled by the user, although, even if this is done, theSafariweb browser will continue to send search terms to Apple unless the function is separately disabled.
