History of Apple tree'south current Mac operating system

For the history of the classic Macintosh operating system (1984–2001), meet Archetype Mac Bone.


The history of macOS, Apple'due south current Mac operating system formerly named Mac Bone X until 2012 and then OS Ten until 2016, began with the company's project to replace its "archetype" Mac Os. That system, upwards to and including its final release Mac Bone 9, was a directly descendant of the operating arrangement Apple had used in its Macintosh computers since their introduction in 1984. Even so, the current macOS is a Unix operating system built on technology that had been adult at Side by side from the 1980s until Apple purchased the visitor in early on 1997.

Although it was originally marketed every bit simply "version 10" of the Mac Os (indicated by the Roman numeral "X"), it has a completely different codebase from Mac OS nine, likewise as substantial changes to its user interface. The transition was a technologically and strategically meaning one. To ease the transition, versions through ten.4 were able to run Mac OS 9 and its applications in a compatibility layer.

MacOS was first released in 1999 as Mac OS X Server 1.0, with a widely released desktop version—Mac Os X 10.0—following in March 2001. Since then, several more singled-out desktop and server editions of macOS have been released. Starting with Mac Os X 10.7 Lion, macOS Server is no longer offered as a carve up operating system; instead, server management tools are available for purchase as an add-on. Starting with the Intel build of Mac OS X x.5 Leopard, almost releases accept been certified as Unix systems conforming to the Unmarried Unix Specification.[1] [ii] [three] [4] [v]

Lion was sometimes referred to by Apple as "Mac OS X Lion" and sometimes referred to as "OS X Lion", without the "Mac"; Mountain Lion was consistently referred to as just "Bone X Mountain Panthera leo", with the "Mac" existence completely dropped. The operating system was further renamed to "macOS" starting with macOS Sierra.

macOS retained the major version number ten throughout its development history until the release of macOS eleven Big Sur in 2020; releases of macOS have besides been named later large cats (versions 10.0–10.viii) or locations in California (10.9–present).

The electric current major version, macOS 12 Monterey, was appear in WWDC 2021[vi] and released on Oct 25 of that twelvemonth;[7] the latest version of macOS 12, macOS 12.3, was released on March 14, 2022.[8]

Development [edit]

Evolution exterior Apple [edit]

A diagram of the relationships between Unix systems including the ancestors of macOS

After Apple removed Steve Jobs from management in 1985, he left the company and attempted to create the "next big matter", with funding from Ross Perot[9] and himself. The consequence was the Adjacent Computer. As the start workstation to include a digital point processor (DSP) and a high-chapters optical disc drive, NeXT hardware was advanced for its time, but was expensive relative to the rapidly commoditizing workstation market and marred past design issues. The hardware was phased out in 1993; however, the company'due south object-oriented operating system NeXTSTEP had a more lasting legacy.[ commendation needed ]

NeXTSTEP was based on the Mach kernel developed at CMU (Carnegie Mellon Academy)[10] and BSD, an implementation of Unix dating back to the 1970s. It featured an object-oriented programming framework based on the Objective-C language. This environment is known today in the Mac globe as Cocoa. It also supported the innovative Enterprise Objects Framework database access layer and WebObjects awarding server development environment, among other notable features.[ citation needed ]

All but abandoning the thought of an operating arrangement, NeXT managed to maintain a concern selling WebObjects and consulting services, simply ever making modest profits in its last few quarters as an independent visitor. NeXTSTEP underwent an evolution into OPENSTEP which separated the object layers from the operating system below, assuasive information technology to run with less modification on other platforms. OPENSTEP was, for a short fourth dimension, adopted by Sun and HP.

Nonetheless, by this point, a number of other companies — notably Apple, IBM, Microsoft, and even Sun itself — were claiming they would soon be releasing similar object-oriented operating systems and evolution tools of their ain. Some of these efforts, such as Taligent, did non fully come to fruition; others, similar Coffee, gained widespread adoption.[ citation needed ]

On Feb 4, 1997, Apple Computer acquired NeXT for $427 million, and used OPENSTEP every bit the footing for Mac OS X, as it was called at the fourth dimension.[11] Traces of the NeXT software heritage can still be seen in macOS. For example, in the Cocoa development environment, the Objective-C library classes have "NS" prefixes, and the HISTORY section of the manual page for the defaults control in macOS straightforwardly states that the command "Beginning appeared in NeXTStep."[ citation needed ]

Internal development [edit]

Meanwhile, Apple tree was facing commercial difficulties of its own. The decade-quondam Macintosh System Software had reached the limits of its single-user, branch multitasking architecture, and its once-innovative user interface was looking increasingly outdated. A massive development effort to replace it, known as Copland, was started in 1994, simply was more often than not perceived outside Apple to be a hopeless example due to political infighting and conflicting goals. By 1996, Copland was nowhere near ready for release, and the projection was eventually cancelled. Some elements of Copland were incorporated into Mac Os 8, released on July 26, 1997.

After considering the buy of BeOS — a multimedia-enabled, multi-tasking OS designed for hardware similar to Apple'south, the company decided instead to acquire NeXT and employ OPENSTEP as the basis for their new OS. Avie Tevanian took over Bone development, and Steve Jobs was brought on equally a consultant. At first, the program was to develop a new operating organization based nearly entirely on an updated version of OPENSTEP, with the addition of a virtual machine subsystem — known every bit the Blue Box — for running "classic" Macintosh applications. The consequence was known past the code name Rhapsody, slated for release in belatedly 1998.

Apple expected that developers would port their software to the considerably more powerful OPENSTEP libraries one time they learned of its ability and flexibility. Instead, several major developers such as Adobe told Apple that this would never occur, and that they would rather leave the platform entirely. This "rejection" of Apple tree's program was largely the outcome of a string of previous cleaved promises from Apple; subsequently watching i "next OS" after another disappear and Apple tree's market share dwindle, developers were non interested in doing much work on the platform at all, let alone a re-write.

Changed direction under Jobs [edit]

Apple's financial losses continued and the board of directors lost conviction in CEO Gil Amelio, asking him to resign. The lath asked Steve Jobs to atomic number 82 the company on an acting ground, essentially giving him carte blanche to brand changes to render the company to profitability. When Jobs announced at the World Broad Developer's Briefing that what developers actually wanted was a modern version of the Mac Os, and Apple tree was going to deliver information technology[ citation needed ], he was met with applause.

Over the next ii years, a major effort was applied to porting the original Macintosh APIs to Unix libraries known as Carbon. Mac OS applications could be ported to Carbon without the demand for a complete re-write, making them operate every bit native applications on the new operating organisation. Meanwhile, applications written using the older toolkits would be supported using the "Classic" Mac OS ix environs. Back up for C, C++, Objective-C, Java, and Python were added, furthering developer comfort with the new platform.[ citation needed ]

During this time, the lower layers of the operating system (the Mach kernel and the BSD layers on top of it[12]) were re-packaged and released under the Apple Public Source License. They became known as Darwin. The Darwin kernel provides a stable and flexible operating system, which takes advantage of the contributions of programmers and independent open-source projects outside Apple; however, information technology sees trivial use outside the Macintosh community[ commendation needed ].

During this period, the Java programming language had increased in popularity, and an effort was started to amend Mac Coffee back up. This consisted of porting a high-speed Java virtual machine to the platform, and exposing macOS-specific "Cocoa" APIs to the Java language.[ citation needed ]

The starting time release of the new Bone — Mac OS X Server i.0 — used a modified version of the Mac OS GUI, simply all client versions starting with Mac Bone X Developer Preview 3 used a new theme known as Aqua. Aqua was a substantial deviation from the Mac OS 9 interface, which had evolved with piffling alter from that of the original Macintosh operating system: it incorporated total color scalable graphics, anti-aliasing of text and graphics, faux shading and highlights, transparency and shadows, and animation. A new characteristic was the Dock, an application launcher which took advantage of these capabilities.

Despite this, Mac Os X maintained a substantial degree of consistency with the traditional Mac OS interface and Apple tree'southward ain Human Interface Guidelines, with its pull-down menu at the top of the screen, familiar keyboard shortcuts, and support for a single-push button mouse. The development of Aqua was delayed somewhat by the switch from OpenStep's Display PostScript engine to 1 developed in-house that was free of any license restrictions, known as Quartz.[ citation needed ]

Releases [edit]

Note ane The PowerMac G5 had special Jaguar builds.
Note 2 Tiger did non back up 64-fleck GUI applications, but 64-chip CLI applications.[33] [34]
Annotation iii 32-scrap (only not 64-bit) PowerPC applications were supported on Intel processors with Rosetta.
Note 4 64-chip Intel applications are supported on Apple tree silicon Macs with Rosetta 2. However, Intel-based Macs are unable to run ARM-based applications, such every bit iOS and iPadOS apps.

With the exception of Mac Os X Server 1.0 and the original public beta, the outset several macOS versions were named after big cats. Prior to its release, version 10.0 was code named "Cheetah" internally at Apple tree, and version 10.i was lawmaking named internally as "Puma".

After the code proper noun "Jaguar" for version 10.two received publicity in the media, Apple tree began openly using the names to promote the operating system: 10.three was marketed equally "Panther", 10.4 as "Tiger", ten.5 as "Leopard", 10.half dozen as "Snow Leopard", 10.seven as "Lion", and 10.8 every bit "Mountain Lion". "Panther", "Tiger", and "Leopard" were registered as trademarks.

Apple registered "Lynx" and "Cougar", merely these were allowed to lapse.[35] Apple instead used the name of iconic locations in California for subsequent releases: x.9 Mavericks is named subsequently Mavericks, a pop surfing destination; ten.10 Yosemite is named afterward Yosemite National Park; 10.xi El Capitan is named for the El Capitan rock formation in Yosemite National Park; 10.12 Sierra is named for the Sierra Nevada mount range; and ten.13 High Sierra is named for the area around the High Sierra Camps.[ citation needed ]

Public Beta: "Kodiak" [edit]

On September thirteen, 2000, Apple released a $29.95[36] "preview" version of Mac Os 10 (internally codenamed Kodiak) in lodge to gain feedback from users.[37] Information technology marked the get-go public availability of the Aqua interface, and Apple made many changes to the UI based on customer feedback. Mac Os Ten Public Beta expired and ceased to function in jump 2001.[38]

Version 10.0: "Cheetah" [edit]

On March 24, 2001, Apple released Mac OS 10 10.0 (internally codenamed Cheetah).[39] The initial version was slow, incomplete, and had very few applications bachelor at the time of its launch, mostly from independent developers. While many critics suggested that the operating system was not ready for mainstream adoption, they recognized the importance of its initial launch as a base on which to improve. Simply releasing Mac OS 10 was received by the Macintosh community as a peachy accomplishment, for attempts to completely overhaul the Mac OS had been underway since 1996, and delayed past countless setbacks. Post-obit some bug fixes, kernel panics became much less frequent.

Version 10.one: "Puma" [edit]

Mac Bone Ten x.1 (internally codenamed Puma) was released on September 25, 2001.[40] It has amend performance and provided missing features, such as DVD playback. Apple released 10.1 every bit a costless upgrade CD for x.0 users. Apple released a United states$129 upgrade CD for Mac Bone 9.

On January 7, 2002, Apple announced that Mac OS X was to be the default operating system for all Macintosh products by the end of that month.[41]

Version 10.2: "Jaguar" [edit]

On August 23, 2002,[42] Apple followed up with Mac Os X 10.2 Jaguar, the first release to use its code proper name as part of the branding.[43] It brought bully raw functioning improvements, a sleeker expect, and many powerful user-interface enhancements (over 150, according to Apple tree[44] ), including Quartz Extreme for compositing graphics straight on an ATI Radeon or Nvidia GeForce2 MX AGP-based video carte with at to the lowest degree 16 MB of VRAM, a system-wide repository for contact information in the new Address Book, and an instant messaging client named iChat.[45] The Happy Mac which had appeared during the Mac Bone startup sequence for almost 18 years was replaced with a large grayness Apple logo with the introduction of Mac OS X 10.2.

Version ten.3: "Panther" [edit]

Mac Os X Panther was released on Oct 24, 2003. In addition to providing much improved operation, information technology also incorporated the about extensive update even so to the user interface. Panther included as many or more than new features as Jaguar had the year before, including an updated Finder, incorporating a brushed-metallic interface, Fast user switching, Exposé (Window manager), FileVault, Safari, iChat AV (which added videoconferencing features to iChat), improved Portable Certificate Format (PDF) rendering and much greater Microsoft Windows interoperability.[46] Back up for some early on G3 computers such as the Ability Macintosh and PowerBook was discontinued.

Version 10.4: "Tiger" [edit]

Mac OS X Tiger was released on April 29, 2005. Apple stated that Tiger contained more than 200 new features.[47] As with Panther, certain older machines were no longer supported; Tiger requires a Mac with a built-in FireWire port. Among the new features, Tiger introduced Spotlight, Dashboard, Smart Folders, updated Mail plan with Smart Mailboxes, QuickTime 7, Safari ii, Automator, VoiceOver, Core Epitome and Core Video. The initial release of the Apple TV used a modified version of Tiger with a different graphical interface and fewer applications and services.[48]

On January ten, 2006, Apple released the starting time Intel-based Macs along with the 10.four.4 update to Tiger. This operating arrangement functioned identically on the PowerPC-based Macs and the new Intel-based machines, with the exception of the Intel release dropping support for the Classic environment.[48] Only PowerPC Macs can be booted from retail copies of the Tiger customer DVD, but there is a Universal DVD of Tiger Server 10.4.7 (8K1079) that can boot both PowerPC and Intel Macs.

Version x.5: "Leopard" [edit]

Mac OS X Leopard was released on October 26, 2007. Apple called it "the largest update of Mac Bone Ten". Leopard supports both PowerPC- and Intel x86-based Macintosh computers; support for the G3 processor was dropped and the G4 processor required a minimum clock rate of 867 MHz, and at least 512 MB of RAM to be installed. The single DVD works for all supported Macs (including 64-bit machines). New features include a new look, an updated Finder, Fourth dimension Auto, Spaces, Boot Army camp pre-installed,[49] full support for 64-bit applications (including graphical applications), new features in Mail and iChat, and a number of new security features.

Leopard is an Open up Brand UNIX 03 registered product on the Intel platform. It was too the first BSD-based OS to receive UNIX 03 certification.[1] [fifty] Leopard dropped support for the Classic Environment and all Classic applications,[51] and was the concluding version of Mac OS X to support the PowerPC architecture.

Version x.6: "Snow Leopard" [edit]

Mac Os Ten Snow Leopard was released on Baronial 28, 2009, the final version to be bachelor on disc. Rather than delivering big changes to the appearance and cease user functionality like the previous releases of Mac Bone X, the evolution of Snow Leopard was deliberately focused on "under the hood" changes, increasing the performance, efficiency, and stability of the operating arrangement. For most users, the nearly noticeable changes are these: the disk infinite that the operating system frees up after a clean installation compared to Mac Bone Ten 10.5 Leopard, a more responsive Finder rewritten in Cocoa, faster Time Machine backups, more reliable and user friendly deejay ejects, a more powerful version of the Preview application, as well equally a faster Safari spider web browser.[52]

An update introduced back up for the Mac App Store, Apple'south digital distribution platform for macOS applications and subsequent macOS upgrades.[52] Snow Leopard just supports machines with Intel CPUs, requires at least 1 GB of RAM, and drops default support for applications built for the PowerPC architecture (Rosetta can exist installed every bit an additional component to retain back up for PowerPC-only applications).[53]

Version 10.7: "Lion" [edit]

Mac OS X Lion was released on July twenty, 2011. It brought developments fabricated in Apple'southward iOS, such every bit an hands navigable display of installed applications (Launchpad) and (a greater use of) multi-touch gestures, to the Mac. This release removed Rosetta, making it incapable of running PowerPC applications. It dropped support for 32-bit Intel processors and requires 2GB of memory. Changes made to the GUI (Graphical User Interface) include the Launchpad (similar to the habitation screen of iOS devices), auto-hiding scrollbars that only appear when they are being used, and Mission Control, which unifies Exposé, Spaces, Dashboard, and full-screen applications within a single interface.[54] Apple tree likewise made changes to applications: they resume in the same state as they were before they were closed (similar to iOS). Documents motorcar-salvage by default.

Version ten.viii: "Mount Panthera leo" [edit]

OS Ten Mountain King of beasts was released on July 25, 2012. Information technology incorporates some features seen in iOS five, which include Game Center, support for iMessage in the new Messages messaging awarding, and Reminders every bit a to-exercise listing app split up from iCal (which is renamed as Calendar, similar the iOS app). It too includes support for storing iWork documents in iCloud. 2GB of retention is required.[55] Notification Eye, which makes its debut in Mountain King of beasts, is a desktop version like to the 1 in iOS 5.0 and higher. Application popular-ups are at present concentrated on the corner of the screen, and the Center itself is pulled from the right side of the screen. Mountain Lion as well includes more than Chinese features, including support for Baidu as an pick for Safari search engine.[56] Notification Center is added, providing an overview of alerts from applications. Notes is added, as an awarding divide from Postal service, synching with its iOS counterpart[57] [58] through the iCloud service. Messages, an instant messaging software awarding,[59] replaces iChat.[threescore]

Version 10.9: "Mavericks" [edit]

OS X Mavericks was released on Oct 22, 2013, equally a gratuitous update through the Mac App Store worldwide.[61] It placed accent on battery life, Finder enhancements, other enhancements for ability users, and continued iCloud integration, as well as bringing more of Apple's iOS apps to the Os 10 platform. iBooks and Apple Maps applications were added. Mavericks requires 2GB of memory to operate. It is the first version named under Apple tree's then-new theme of places in California, dubbed Mavericks after the surfing location.[62] [63] Unlike previous versions of OS X, which had progressively decreasing prices since ten.6, 10.9 was bachelor at no charge to all users of uniform systems running Snow Leopard (ten.half dozen) or later,[64] beginning Apple'due south policy of free upgrades for life on its operating system and business software.[65]

Version ten.ten: "Yosemite" [edit]

Bone X Yosemite was released to the general public on October xvi, 2014, as a free update through the Mac App Store worldwide. It featured a major overhaul of user interface, replaced skeuomorphism with apartment graphic design and blurred translucency effects, following the artful introduced with iOS 7. It introduced features called Continuity and Handoff, which allow for tighter integration between paired OS X and iOS devices: the user tin handle phone calls or text messages on either their Mac or their iPhone, and edit the same Pages document on either their Mac or their iPad. A afterwards update of the Bone included Photos as a replacement for iPhoto and Aperture.[ citation needed ]

Version x.xi: "El Capitan" [edit]

Bone X El Capitan was revealed on June 8, 2015, during the WWDC keynote speech communication.[66] Information technology was made available as a public beta in July and was fabricated available publicly on September 30, 2015. Apple described this release as containing "Refinements to the Mac Experience" and "Improvements to Arrangement Performance" rather than new features. Refinements include public transport built into the Maps application, GUI improvements to the Notes application, besides equally adopting San Francisco equally the system font. Metallic API, an application enhancing software, had debuted in this operating system, existence available to "all Macs since 2012".[67]

Version ten.12: "Sierra" [edit]

macOS Sierra was announced on June 13, 2016, during the WWDC keynote speech communication. The update brought Siri to macOS, featuring several Mac-specific features, like searching for files. It also allowed websites to support Apple Pay as a method of transferring payment, using either a nearby iOS device or Touch ID to authenticate. iCloud too received several improvements, such as the power to store a user's Desktop and Documents folders on iCloud so they could exist synced with other Macs on the same Apple ID. It was released publicly on September 20, 2016.[68]

Version ten.13: "High Sierra" [edit]

macOS High Sierra was appear on June 5, 2017, during the WWDC keynote speech. It was released on September 25, 2017. The release includes many nether-the-hood improvements, including a switch to Apple File Organisation (APFS), the introduction of Metal 2, support for HEVC video, and improvements to VR back up. In addition, numerous changes were made to standard applications including Photos, Safari, Notes, and Spotlight.[69]

Version ten.xiv: "Mojave" [edit]

macOS Mojave was announced on June 4, 2018, during the WWDC keynote oral communication. It was released on September 24, 2018. Some of the central new features were the Nighttime way, Desktop stacks and Dynamic Desktop, which changes the desktop background image to correspond to the user's current time of day.[70]

Version 10.fifteen: "Catalina" [edit]

macOS Catalina was announced on June 3, 2019, during the WWDC keynote speech. It was released on Oct 7, 2019. It primarily focuses on updates to built-in apps, such as replacing iTunes with split up Music, Podcasts, and Tv apps, redesigned Reminders and Books apps, and a new Find My app. Information technology besides features Sidecar, which allows the user to employ an iPad as a second screen for their calculator, or even simulate a graphics tablet with an Apple Pencil. It is the first version of macOS non to support 32-bit applications. The Dashboard application was as well removed in the update.[71] [72] Since macOS Catalina, iOS apps can run on macOS with Project Catalyst merely requires the app to exist made compatible[73] dissimilar ARM-powered Silicon Macs that can run all iOS apps by default.[74]

Version 11: "Big Sur" [edit]

macOS Big Sur was announced on June 22, 2020, during the WWDC keynote voice communication.[75] Information technology was released November 12, 2020.[76] The major version number is changed, for the first time since "Mac Os 10" was released, making it macOS 11. It brings ARM back up, new icons, GUI changes to the arrangement,[77] and other bug fixes.

Version 12: "Monterey" [edit]

macOS Monterey was announced on June 7, 2021, during the WWDC keynote speech. Information technology was released on October 25, 2021. macOS Monterey introduces new features such as Universal Control, AirPlay to Mac, Shortcuts awarding, and more. Universal Control allows users to use a unmarried Keyboard and Mouse to move between devices. Airplay at present allows users to present and share almost anything. The Shortcuts app was as well introduced to macOS, giving users access to galleries of pre-built shortcuts, designed for Macs, a service brought from iOS. Users can now as well set upwards shortcuts, among other things.
