Query: When was Mac OS first developed?
macOS (formerly "Mac OS X" and later "OS X") is a line of open core graphical operating systems developed, marketed, and sold by Apple Inc., the latest of which is pre-loaded on all currently shipping Macintosh computers. macOS is the successor to the original classic Mac OS, which had been Apple's primary operating system since 1984. Unlike its predecessor, macOS is a UNIX operating system built on technology that had been developed at NeXT through the second half of the 1980s and up until Apple purchased the company in early 1997.
The operating system was first released in 1999 as Mac OS X Server 1.0, followed in March 2001 by a client version (Mac OS X v10.0 "Cheetah"). Since then, six more distinct "client" and "server" editions of macOS have been released, until the two were merged in OS X 10.7 "Lion".
The Macintosh Application Environment (MAE) was a software package introduced by Apple in 1994 that allowed users of certain Unix-based computer workstations to run Apple Macintosh application software. MAE used the X Window System to emulate a Macintosh Finder-style graphical user interface. The last version, MAE 3.0, was compatible with System 7.5.3. MAE was available for Sun Microsystems SPARCstation and Hewlett-Packard systems. It was discontinued on May 14, 1998.
The Copland development was hampered by many missed deadlines. The release date was first pushed back to the end of 1995, then to mid-1996, late 1996, and finally to the end of 1997. With a dedicated team of 500 software engineers and an annual budget of $250 million, Apple executives began to grow impatient with the project continually falling behind schedule. At the Worldwide Developers Conference in January 1997, Apple chief executive officer (CEO) Gil Amelio announced that, rather than release Copland as one monolithic release, Copland features would be phased into the Mac OS following a six-month release cycle. These updates began with Mac OS 7.6, released during WWDC. Mac OS 8.0, released six months later, continued to integrate Copland technologies into the Mac OS.
The Xerox Alto, developed at Xerox PARC in 1973, was the first computer to use a mouse, the desktop metaphor, and a graphical user interface (GUI), concepts first introduced by Douglas Engelbart while at International. It was the first example of what would today be recognized as a complete personal computer. The first machines were introduced on 1 March 1973,
Development of Swift started in July 2010 by Chris Lattner, with the eventual collaboration of many other programmers at Apple. Swift took language ideas "from Objective-C, Rust, Haskell, Ruby, Python, C#, CLU, and far too many others to list". On June 2, 2014, the Apple Worldwide Developers Conference (WWDC) application became the first publicly released app written with Swift. A beta version of the programming language was released to registered Apple developers at the conference, but the company did not promise that the final version of Swift would be source code compatible with the test version. Apple planned to make source code converters available if needed for the full release.
In 1990, Microsoft introduced its office suite, Microsoft Office. The suite bundled separate productivity applications, such as Microsoft Word and Microsoft Excel. On May 22, Microsoft launched Windows 3.0, featuring streamlined user interface graphics and improved protected mode capability for the Intel 386 processor. Both Office and Windows became dominant in their respective areas.
Microsoft Office is a family of client software, server software, and services developed by Microsoft. It was first announced by Bill Gates on August 1, 1988, at COMDEX in Las Vegas. Initially a marketing term for an office suite (bundled set of productivity applications), the first version of Office contained Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Over the years, Office applications have grown substantially closer with shared features such as a common spell checker, OLE data integration and Visual Basic for Applications scripting language. Microsoft also positions Office as a development platform for line-of-business software under the Office Business Applications brand. On July 10, 2012, Softpedia reported that Office is used by over a billion people worldwide.
In 1983 National Instruments reached an organizational milestone, developing their first GPIB board to connect instruments to IBM PCs. With the arrival of the Macintosh computer, however, the company felt ready to take advantage of the new graphical interfaces. Kodosky began a research initiative with the assistance of student researchers at the University of Texas into ways to exploit the new interface. This led to the creation of NI's flagship product, the LabVIEW graphical development platform for the Macintosh computer, which was released in 1986. The software allows engineers and scientists to program graphically, by "wiring" icons together instead of typing text-based code. By allowing people to use a more intuitive, less-structured development environment, their productivity greatly increased, making LabVIEW quite popular. The following year, a version of LabVIEW, known as LabWindows, was released for the DOS environment.
The first commercial voice dictation product for Mac OS X was IBM's ViaVoice, but ScanSoft, the company that had exclusive global distribution rights to ViaVoice, merged with Nuance and stopped developing ViaVoice for Macintosh. (The first dictation software for Mac OS 9 was Articulate System's PowerSecretary.) Seeing a continued need for a Mac-based speech-to-text solution, MacSpeech was founded in 1996 by Andrew Taylor, a former employee of Articulate Systems experienced with software-based speech recognition technologies.
MacSpeech's first product, iListen, was developed in partnership with Philips Speech Processing using its "FreeSpeech 2000" speech engine. First released in 2000, by 2006 iListen was the only third-party software product that allowed voice-to-text input on the newer MacIntosh models requiring OSX. Its competitors at the time were Apple's own speech recognition software (built into Mac OS X); Dragon Naturally Speaking for PC by Nuance, running under a Windows virtualization software solution such as Parallels Desktop for Mac or VMware Fusion; and the discontinued program ViaVoice by Nuance/IBM.
In January 2008, iListen was discontinued, and replaced by "MacSpeech Dictate" (released February 15, 2008). The firm abandoned the Philips speech engine in favor of the speech-recognition engine Nuance used in its Dragon NaturallySpeaking product for PC. MacSpeech Dictate was a winner of the MacWorld 2008 Best of Show award. In 2009, the firm released several editions of its products for the MacIntosh, including MacSpeech Dictate Medical, MacSpeech Dictate Legal and MacSpeech Dictate International.
MacSpeech Scribe is speech recognition software for Mac OS X designed specifically for transcription of recorded voice dictation. It runs on Mac OS X 10.6 Snow Leopard. The software transcribes dictation recorded by an individual speaker. Typically the speaker will have recorded their dictation using a digital recording device such as a handheld digital recorder, mobile smartphone (e.g. iPhone), or desktop or laptop computer with a suitable microphone. The program supports the audio file formats aif, .aiff, .wav, .mp4, .m4a, and .m4v.
Also in 1973 Hewlett Packard introduced fully BASIC programmable microcomputers that fit entirely on top of a desk, including a keyboard, a small one-line display, and printer. The Wang 2200 microcomputer of 1973 had a full-size cathode ray tube (CRT) and cassette tape storage. These were generally expensive specialized computers sold for business or scientific uses. The introduction of the microprocessor, a single chip with all the circuitry that formerly occupied large cabinets, led to the proliferation of personal computers after 1975.
1974 saw the introduction of what is considered by many to be the first true "personal computer", the Altair 8800 created by Micro Instrumentation and Telemetry Systems (MITS). Based on the 8-bit Intel 8080 Microprocessor, the Altair is widely recognized as the spark that ignited the microcomputer revolution as the first commercially successful personal computer. The computer bus designed for the Altair was to become a "de facto" standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.
The history of game making begins with the development of the first video games, although which video game is the first depends on the definition of "video game". The first games created had little entertainment value, and their development focus was separate from user experience—in fact, these games required mainframe computers to play them. "OXO", written by Alexander S. Douglas in 1952, was the first computer game to use a digital display. In 1958, a game called "Tennis for Two", which displayed its output on an oscilloscope, was made by Willy Higinbotham, a physicist working at the Brookhaven National Laboratory. In 1961, a mainframe computer game called "Spacewar!" was developed by a group of Massachusetts Institute of Technology students led by Steve Russell.
In the Commodore world, GEOS was available on the Commodore 64 and Commodore 128. Later, a version was available for PCs running DOS. It could be used with a mouse or a joystick as a pointing device, and came with a suite of GUI applications. Commodore's later product line, the Amiga platform, ran a GUI operating system by default. The Amiga laid the blueprint for future development of personal computers with its groundbreaking graphics and sound capabilities. "Byte" called it "the first multimedia computer... so far ahead of its time that almost nobody could fully articulate what it was all about."
In 1983, DIAB independently developed the first UNIX-compatible machine, DIAB DS90, based on the Motorola 68000 CPU. DNIX here made its appearance, based on a UNIX System V license from AT&T. DIAB was however an industrial automation company, and needed a real-time operating system, so the company replaced the AT&T-supplied UNIX kernel with their own in-house developed, yet compatible real-time variant. Over time, the company also replaced several of the UNIX standard userspace tools with their own implementations, to the point where no code was derived from UNIX, and their machines could be deployed independently of any AT&T UNIX license. Two years later and in cooperation with Luxor, a computer called ABC 1200 was developed for the office market, while in parallel, DIAB continue to produce enhanced versions of the DS90 computer using newer versions of the Motorola CPUs such as the Motorola 68010, 68020, 68030 and eventually 68040. In 1990, after DIAB was acquired by Groupe Bull, who continued to produce and support the DS machines under the brand name "DIAB", with names such as "DIAB 2320", "DIAB 2340" etc., still running DIABs version of DNIX.
Apple began work on the first iPhone in 2005 and the first iPhone was released on June 29, 2007. The iPhone created such a sensation that a survey indicated six out of ten Americans were aware of its release. "Time" declared it "Invention of the Year" for 2007. The completed iPhone had multimedia capabilities and functioned as a quad-band touch screen smartphone. A year later, the iPhone 3G was released in July 2008 with three key features: support for GPS, 3G data and tri-band UMTS/HSDPA. In June 2009, the iPhone 3GS, whose improvements included voice control, a better camera, and a faster processor, was introduced by Phil Schiller. The iPhone 4 is thinner than previous models, has a five megapixel camera capable of recording video in 720p HD, and adds a secondary front-facing camera for video calls. A major feature of the iPhone 4S, introduced in October 2011, was Siri, a virtual assistant capable of voice recognition.
In 1981, he wired together the backplanes of two DEC VAX-11/780's and made the first multi-CPU Unix computer, preceding DEC's dual processor VAX-11/782. The operating system was based on the 4.2 BSD kernel, and the modifications thus made eventually made it into the 4.3 BSD Unix release. At the beginning of the 4.3 BSD user manuals, Bill Joy wrote a special note of thanks to GHG for being courageous enough to put the multi-CPU kernel into a production environment before anyone else did. (However, the frequent crashes for a while inspired the writing of many humorous text files by the Purdue University Electrical Engineering student body, such as "The VAX had a Blowout", to be sung to the tune of London Bridge is Falling Down). The development of the Dual-CPU Unix system was the subject of Goble's Master's thesis.
The first version of the iPhone became publicly available on June 29, 2007 in selected countries/markets. It was another 12 months before the iPhone 3G became available on July 11, 2008. Apple announced the iPhone 3GS on June 8, 2009, along with plans to release it later in June, July, and August, starting with the U.S., Canada and major European countries on June 19. This 12-month iteration cycle has continued with the iPhone 4 model arriving in similar fashion in 2010, a Verizon model was released in February 2011, and a Sprint model in October 2011, shortly after Jobs' death.
Siri is a spin-off from a project originally developed by the SRI International Artificial Intelligence Center. Its speech recognition engine was provided by Nuance Communications, and Siri uses advanced machine learning technologies to function. Its original American, British, and Australian voice actors recorded their respective voices around 2005, unaware of the recordings' eventual usage in Siri. The voice assistant was released as an app for iOS in February 2010, and it was acquired by Apple two months later. Siri was then players said the game could into iPhone 4S at its release in October 2011. At that time, the separate app was also removed from the iOS App Store. Siri has since become an integral part of Apple's products, having been adapted into other hardware devices over the years, including newer iPhone models, as well as iPad, iPod Touch, Mac, AirPods, Apple TV, and HomePod.
In 1998 the term "open-source software" (as abbreviation "OSS") was coined as alternative for "free software". There were several reasons for the proposal of a new term. On one hand a group from the free software ecosystem perceived the Free Software Foundation's attitude on propagandizing the "free software" concept as "moralising and confrontational", which was also associated with the term. In addition, the "available at no cost" ambiguity of the word "free" was seen as discouraging business adoption, as also the historical ambiguous usage of the term "free software". In a 1998 strategy session in California, "open-source software" was selected by Todd Anderson, Larry Augustin, Jon Hall, Sam Ockman, Christine Peterson, and Eric S. Raymond. Richard Stallman had not been invited. The session was arranged in reaction to Netscape's January 1998 announcement of a source code release for Navigator (as Mozilla). Those at the meeting described "open source" as a "replacement label" for free software, and the Open Source Initiative was soon-after founded by Eric Raymond and Bruce Perens to promote the term as part of "a marketing program for free software". The Open Source Definition is used by the Open Source Initiative to determine whether a software license qualifies for the organization's insignia for open source software. The definition was based on the Debian Free Software Guidelines, written and adapted primarily by Bruce Perens. Perens did not base his writing on the four freedoms of free software from the Free Software Foundation, which were only later available on the web. According to the OSI, Stallman initially flirted with the idea of adopting the open source term.
Microsoft Office 97 is a major milestone release of Microsoft Office, which includes hundreds of new features and improvements over its predecessor, Microsoft Office 95. Office 97 introduced "Command Bars," a paradigm in which menus and toolbars were made more similar in capability and visual design. It also featured natural language systems and sophisticated grammar checking. It was published on CD-ROM as well as on a set of 44 3½-inch floppy disks. Released on November 19, 1996,the suite runs on Windows NT 3.51 SP5, Windows 95, Windows NT 4.0 SP2, Windows 98, Windows 2000, and Windows ME. It is the last version to support Windows NT 3.51 as Office 2000 requires Windows 95, Windows NT 4.0 SP3 or a later version. Two service releases (SR-1 and SR-2) were released for Office 97. SR-2 solved the year 2000 problem in Office 97.
Siri was originally released as a stand-alone application for the iOS operating system in February 2010, and at the time, the developers were also intending to release Siri for Android and BlackBerry devices. Two months later, Apple acquired Siri. On October 4, 2011, Apple introduced the iPhone 4S with a beta version of Siri. After the announcement, Apple removed the existing standalone Siri app from App Store. "TechCrunch" wrote that, despite the Siri app's support for iPhone 4, its removal from App Store might also have had a financial aspect for the company, in providing an incentive for customers to upgrade devices. Third-party developer Steven Troughton-Smith, however, managed to port Siri to iPhone 4, though without being able to communicate with Apple's servers. A few days later, Troughton-Smith, working with an anonymous person nicknamed "Chpwn", managed to fully hack Siri, enabling its full functionalities on iPhone 4 and iPod Touch devices. Additionally, developers were also able to successfully create and distribute legal ports of Siri to any device capable of running iOS 5, though a proxy server was required for Apple server interaction.
Over the years, Apple has expanded the line of officially supported products, including newer iPhone models, as well as iPad support in June 2012, iPod Touch support in September 2012, Apple TV support, and the stand-alone Siri Remote, in September 2015, Mac and AirPods support in September 2016, and HomePod support in February 2018.
Around the same time, Douglas Engelbart used computer screens both as input and output devices. In 1968, Ivan Sutherland, with the help of many students including Bob Sproull, created what was widely considered to be the first head-mounted display (HMD) system for use in immersive simulation applications. It was primitive both in terms of user interface and realism, and the HMD to be worn by the user was so heavy that it had to be suspended from the ceiling. The graphics comprising the virtual environment were simple wire-frame model rooms. The formidable appearance of the device inspired its name, The Sword of Damocles.
The consumer version of Mac OS X was launched in 2001 with Mac OS X 10.0. Reviews were variable, with extensive praise for its sophisticated, glossy Aqua interface but criticizing it for sluggish performance. With Apple's popularity at a low, the makers of several classic Mac applications such as FrameMaker and PageMaker declined to develop new versions of their software for Mac OS X. "Ars Technica" columnist John Siracusa, who reviewed every major OS X release up to 10.10, described the early releases in retrospect as 'dog-slow, feature poor' and Aqua as 'unbearably slow and a huge resource hog'.
Mac OS X, based on NeXT's OPENSTEP and BSD Unix, was released on March 24, 2001, after several years of development. Aimed at consumers and professionals alike, Mac OS X aimed to combine the stability, reliability, and security of Unix with the ease of use afforded by an overhauled user interface. To aid users in migrating from Mac OS 9, the new operating system allowed the use of OS 9 applications within Mac OS X via the Classic Environment.
In May 2002, at Apple's Worldwide Developers Conference in San Jose, California, Steve Jobs, accompanied by a coffin, held a mock funeral to announce that Apple had stopped development of Mac OS 9. Mac OS 9.2.2, released in December 2001, was the final version of Mac OS 9 and the "classic" Mac OS.
In June 2005, Jobs announced that the Macintosh platform would be transitioning to Intel x86 microprocessors. Developer documentation of the Rosetta PowerPC emulation layer revealed that applications written for Mac OS 8 or 9 would not run on x86-based Macs. The Classic Environment remains in the PowerPC version of OS X 10.4; however, x86 versions of OS X do not support the Classic environment.
macOS is based on technologies developed between 1985 and 1997 at NeXT, a company that Apple co-founder Steve Jobs created after leaving the company. The "X" in Mac OS X and OS X is the Roman numeral for the number 10 and is pronounced as such. The X was a prominent part of the operating system's brand identity and marketing in its early years, but gradually receded in prominence since the release of Snow Leopard in 2009. UNIX 03 certification was achieved for the Intel version of Mac OS X 10.5 Leopard and all releases from Mac OS X 10.6 Snow Leopard up to the current version also have UNIX 03 certification. macOS shares its Unix-based core, named Darwin, and many of its frameworks with iOS, tvOS and watchOS. A heavily modified version of Mac OS X 10.4 Tiger was used for the first-generation Apple TV.
