2011–present: Restructuring and Apple Watch

On March 2, 2011, Apple unveiled the iPad's second generation model, the iPad 2. Like the 4th generation iPod Touch and iPhone, the iPad 2 comes with a front-facing camera as well as a rear-facing camera, along with three new apps that utilize these new features: Camera, FaceTime, and Photobooth (only on iPad2).
On August 24, 2011, Steve Jobs resigned from his position as CEO with Tim Cook taking his place. On October 29, 2012, Apple announced structural changes to increase collaboration between hardware, software and services. This involved the departure of Scott Forstall, responsible for the launch of iOS (iPhone OS at the time of launch), who was replaced with Craig Federighi as head of iOS and OS X teams. Jony Ive became head of HI (Human Interface), whilst Eddy Cue was announced as head of online services including Siri and Maps. The most notable short term difference of this restructuring was the launch of iOS 7, the first version of the operating system to use a drastically different design to its predecessors, headed by Jony Ive., followed by OS X Yosemite a year later with a similar design.
During this time, Apple released the iPhone 5, the first iPhone to have a screen larger than 3.5", the iPod Touch 5, also with a 4" screen, the iPhone 5S with fingerprint scanning technology in the form of Touch ID, and iPhone 6 and iPhone 6 Plus, with screens at 4.7" and 5.5". They released the iPad 3rd generation with Retina Display, followed by the iPad (4th generation) just half a year later. The iPad Mini was announced alongside the iPad 4th gen, and was the first to feature a smaller screen than 9.7". This was followed by the iPad Mini 2 with Retina Display in 2013, alongside the iPad Air, a continuation of the original 9.7" range of iPads, which was subsequently followed by the iPad Air 2 with Touch ID in 2014. Apple also released various major Mac updates, including the MacBook Pro with Retina Display, whilst also discontinuing the original MacBook range for a short period, before reintroducing it in 2015 with various new features, a Retina Display and a new design notably absent of ports other than USB-C. They also updated the Mac Pro and iMac lines with a drastically different smaller/thinner, but more powerful designs.
On November 25, 2013, Apple acquired a company called PrimeSense. On May 28, 2014, Apple acquired Beats Electronics, producers of the popular Beats by Dre headphone and speaker range, as well as streaming service Beats Music.
On September 9, 2014, Apple announced the Apple Watch, the first new product range since the departure of Steve Jobs. The product cannot function beyond basic features without being within Bluetooth or WiFi range to an iPhone, and contains basic applications (many acting as a remote for other devices, such as a music remote, or a control for an Apple TV) and fitness tracking. The Apple Watch received mixed reviews, with critics suggesting that whilst the device showed promise, it lacked a clear purpose, similar to many of the devices already on the market. The Apple Watch was released on April 24, 2015.
On September 9, 2015, Apple announced the iPhone 6S and iPhone 6S Plus with 3D Touch, the iPad Pro, and the fourth-generation Apple TV, along with the fourth-generation iPad Mini.

2007–2011: Apple Inc., iPhone, iOS, iPad

On January 9, 2007, Apple Computer, Inc. shortened its name to simply Apple Inc. In his Macworld Expo keynote address, Steve Jobs explained that with their current product mix consisting of the iPod and Apple TV as well as their Macintosh brand, Apple really wasn't just a computer company anymore. At the same address, Jobs revealed a product that would revolutionize an industry in which Apple had never previously competed: the Apple iPhone. The iPhone combined Apple's first widescreen iPod with the world's first mobile device boasting visual voicemail, and an internet communicator able to run a fully functional version of Apple's web browser, Safari, on the then-named iPhone OS (later renamed iOS).
iOS evolution: iPhone and iPad
Main articles: iOS, iPhone and iPad
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.
On February 10, 2011, the iPhone 4 was made available on both Verizon Wireless and AT&T. Now two iPod types are multi-touch: the iPod nano and the iPod touch, a big advance in technology. Apple TV currently has a 2nd generation model, which is 4 times smaller than the original Apple TV. Apple has also gone wireless, selling a wireless trackpad, keyboard, mouse, and external hard drive. Wired accessories are, however, still available.
The Apple iPad was announced on January 27, 2010 with retail availability commencing in April and systematically growing in markets throughout 2010. The iPad fits into Apple's iOS product line, being twice the screen size of an iPhone without the phone abilities. While there were initial fears of product cannibalisation the FY2010 financial results released in Jan 2011 included commentary of a reverse 'halo' effect, where iPad sales were leading to increased sales of iMacs and MacBooks.
Resurgence compared to Microsoft
Since 2005, Apple's revenues, profits, and stock price have grown significantly. On May 26, 2010 Apple's stock market value overtook Microsoft's, and Apple's revenues surpassed those of Microsoft in the third quarter of 2010. After giving their results for the first quarter of 2011 Microsoft's net profits of $5.2 billion were lower for the quarter than those of Apple Inc., which earned $6 billion in net profit for the quarter. The late April announcement of profits by the Five companies marks the first time in twenty years that Microsoft's profits have been lower than Apple's., and according to Arstechnica "this would have been 'unimaginable' 10 years before."

The Guardian reported that one of the reasons for the change is because PC software, where Microsoft dominates, has become less important compared to the tablet PC and smartphone markets, where Apple has a strong presence. One reason for this was a surprise drop in PC sales in the quarter. Another issue for Microsoft is that their online search business has lost a lot of money, with a loss of $700 million in the first quarter of 2010. Although Microsoft's online division losses were high, even if they had made no loss Apple's profits would have been slightly higher.

2001–2007: iPods, iTunes Store, Intel transition

iPod


A 2nd generation iPod
iPod mini with the user interface set to German
In October 2001, Apple introduced its first iPod portable digital audio player. The iPod started as a 5 gigabyte player capable of storing around 1000 songs. Since then it has evolved into an array of products including the Mini (now discontinued), the iPod Touch, the Shuffle, the iPod Classic, the Nano, the iPhone and the iPad. Since March 2011, the largest storage capacity for an iPod has been 160 gigabytes. Speaking to software developers on June 6, 2005, Steve Jobs said the company's share of the entire portable music device market stood at 76%.
The iPod gave an enormous lift to Apple's financial results. In the quarter ending March 26, 2005, Apple earned US$290 million, or 34¢ a share, on sales of US$3.24 billion. The year before in the same quarter, Apple earned just US$46 million, or 6¢ a share, on revenue of US$1.91 billion.
Moving on from colored plastics and the PowerPC G3
In early 2002, Apple unveiled a completely redesigned iMac, using the G4 processor and LCD display. The new iMac G4 design had a white hemispherical base and a flat panel all-digital display supported by a swiveling chrome neck. After several iterations increasing the processing speed and screen sizes from 15" to 17" to 20" the iMac G4 was discontinued and replaced by the iMac G5 in the summer of 2004.
In 2002, Apple also released the Xserve 1U rack mounted server. Originally featuring two G4 chips, the Xserve was unusual for Apple in two ways. It represented an earnest effort to enter the enterprise computer market and it was also relatively cheaper than similar machines released by its competitors. This was due, in no small part, to Apple's use of Fast ATA drives as opposed to the SCSI hard drives used in traditional rack-mounted servers. Apple later released the Xserve RAID, a 14 drive RAID which was, again, cheaper than competing systems.
In mid-2003, Steve Jobs launched the Power Mac G5, based on IBM's G5 processor. Its all-metal anodized aluminum chassis finished Apple's transition away from colored plastics in their computers. Apple claims this was the first 64-bit computer sold to the general public. The Power Mac G5 was also used by Virginia Tech to build its prototype System X supercomputing cluster, which at the time garnered the prestigious recognition of the third fastest supercomputer in the world. It cost only US$5.2 million to build, far less than the previous No. 3 and other ranking supercomputers. Apple's Xserves were soon updated to use the G5 as well. They replaced the Power Mac G5 machines as the main building block of Virginia Tech's System X, which was ranked in November 2004 as the world's seventh fastest supercomputer.
A new iMac based on the G5 processor was unveiled August 31, 2004 and was made available in mid-September. This model dispensed with the base altogether, placing the CPU and the rest of the computing hardware behind the flat-panel screen, which is suspended from a streamlined aluminum foot. This new iMac, dubbed the iMac G5, was the world's thinnest desktop computer, measuring in at around two inches (around 5 centimeters).
2004, however, was a turning point for Apple. After creating a sizable financial base to work with, the company began experimenting with new parts from new suppliers. As a result, Apple was able to produce new designs quickly over a short amount of time, with the release of the iPod Video, then the iPod Classic, and eventually the iPod touch and iPhone.
On April 29, 2005, Apple released Mac OS X v10.4 "Tiger" to the general public.
Apple's wildly successful PowerBook and iBook products relied on Apple's previous generation G4 architecture which were produced by Freescale Semiconductor, a spin-off from Motorola. Engineers at IBM had minimal success in making their PowerPC G5 processor consume less power and run cooler but not enough to run in iBook or PowerBook formats. As of the week of October 24, 2005 Apple released the Power Mac G5 Dual that features a Dual-Core processor. This processor contains two cores in one rather than have two separate processors. Apple has also developed the Power Mac G5 Quad that uses two of the Dual-Core processors for enhanced workstation power and performance. The new Power Mac G5 Dual cores run individually at 2.0 GHz or 2.3 GHz. The Power Mac G5 Quad cores run individually at 2.5 GHz and all variations have a graphics processor that has 256-bit memory bandwidth.
Retail store expansion
Initially, the Apple Stores were only opened in the United States, but in late 2003, Apple opened its first Apple Store abroad, in Tokyo's Ginza district. Ginza was followed by a store in Osaka, Japan in August 2004. In 2005, Apple opened stores in Nagoya, the Shibuya district of Tokyo, Fukuoka, and Sendai. Another store was opened in Sapporo in 2006. Apple's first European store opened in London in November 2004, and is currently the largest store. A store in the Bullring shopping centre in Birmingham opened in April 2005, and the Bluewater shopping centre in Dartford, Kent opened in July 2005. Apple opened its first store in Canada in the middle of 2005 at the Yorkdale Shopping Centre in North York, Toronto. Later on in 2005 Apple opened the Meadowhall Store in Sheffield and the Trafford Centre Store in Manchester (UK). Recent additions in the London area include the Brent Cross Apple Store (January 2006) and the Apple Store in Westfield in Shepherd's Bush (September 2008).
Also, in an effort to court a broader market, Apple opened several "mini" stores in October 2004 in an attempt to capture markets where demand does not necessarily dictate a full scale store. The first of these stores was opened at Stanford Shopping Center in Palo Alto, California. These stores follow in the footsteps of the successful Apple products: iPod mini and Mac mini. These stores are only one half the square footage of the smallest "normal" store and thus can be placed in several smaller markets.
Apple and "i" Web services
In 2000, Apple introduced its iTools service, a set of free web-based tools that included an email account, internet greeting cards called iCards, a service called iReview that gave internet users a place to read and write reviews of Web sites, and a tool called KidSafe which promised to prevent children from browsing inappropriate portions of the web. The latter two services were eventually canceled because of lack of success, while iCards and email became integrated into Apple's .Mac subscription based service introduced in 2002 and discontinued in mid-2008 to make way for the release of the new MobileMe service, coinciding with the iPhone 3G release. MobileMe, which carried the same US$99.00 annual subscription price as its .Mac predecessor, featured the addition of "push" services to instantly and automatically send emails, contacts and calendar updates directly to users' iPhone devices. Some controversy surrounded the release of MobileMe services to users resulting in expected downtime and a significantly longer release window. As a result of this, Apple extended the subscriptions of existing MobileMe subscribers by an additional 30 days free-of-charge. At the WWDC event in June 2011, Apple announced its most up to date cloud service, iCloud, replacing MobileMe. This service kept most of the core services that MobileMe offered, however dropping iDisk, Gallery, and iWeb. Additionally, it added a number of other features to the group, including Find my Mac, iTunes Match, Photo Stream, Documents & Data Backup, and iCloud backup for iOS devices. The service requires users to be running iOS 5 and OS X 10.7 Lion.
iTunes Store
The iTunes Music Store was launched in April 2003, with 2 million downloads in the first 16 days. Music was purchased through the iTunes application, which was initially Macintosh-only; in October 2003, support for Windows was added. Initially, the music store was only available in the United States due to licensing restrictions.
In June 2004 Apple opened their iTunes Music Store in the United Kingdom, France, and Germany. A European Union version opened October 2004 (actually, a Eurozone version; not initially available in the Republic of Ireland due to the intransigence of the Irish Recorded Music Association (IRMA) but eventually opened Thursday January 6, 2005.) A version for Canada opened in December 2004. On May 10, 2005, the iTunes Music Store was expanded to Denmark, Norway, Sweden, and Switzerland.
On December 16, 2004, Apple sold its 200 millionth song on the iTunes Music Store to Ryan Alekman from Belchertown, Massachusetts. The download was The Complete U2, by U2. Just under three months later Apple sold its 300 millionth song on March 2, 2005. On July 17, 2005, the iTunes Music Store sold its 500 millionth song. At that point, songs were selling at an accelerating annualized rate of more than 500 million.
On October 25, 2005, the iTunes Store went live in Australia, with songs selling for A$1.69 each, albums at (generally) A$16.99 and music videos and Pixar short films at A$3.39. Briefly, people in New Zealand were able to buy music off the Australian store. However, that loophole was quickly closed.
On February 23, 2006, the iTunes Music Store sold its 1 billionth song.
The iTunes Music Store changed its name to iTunes Store on September 12, 2006 when it began offering video content (TV shows and movies) for sale. Since iTunes' inception it has sold over 2 billion songs, 1.2 billion of which were sold in 2006. Since downloadable TV and movie content was added 50 million TV episodes and 1.3 million movies have been downloaded.
In early 2010, Apple celebrated the 10 billionth song downloaded from the iTunes Music Store.
Intel transition
In a keynote address on June 6, 2005, Steve Jobs officially announced that Apple would begin producing Intel-based Macintosh computers beginning in 2006. Jobs confirmed rumors that the company had secretly been producing versions of its current operating system Mac OS X for both PowerPC and Intel processors over the past 5 years, and that the transition to Intel processor systems would last until the end of 2007. Rumors of cross-platform compatibility had been spurred by the fact that Mac OS X is based on OpenStep, an operating system that was available for many platforms. In fact, Apple's own Darwin, the open source underpinnings of Mac OS X, was also available for Intel's x86 architecture.
On January 10, 2006, the first Intel-based machines, the iMac and MacBook Pro, were introduced. They were based on the Intel Core Duo platform. This introduction came with the news that Apple would complete the transition to Intel processors on all hardware by the end of 2006, a year ahead of the originally quoted schedule.

1997–2001: Apple's comeback

Return of Steve Jobs
On July 9, 1997, Gil Amelio was ousted as CEO of Apple by the board of directors. Jobs stepped in as the interim CEO to begin a critical restructuring of the company's product line. He would eventually become CEO and served in that position until August 2011. On August 24, 2011 Steve Jobs resigned his position as chief executive officer of Apple before his long battle with pancreatic cancer took his life on October 5, 2011.
On November 10, 1997, Apple introduced the Apple Store, an online retail store based upon the WebObjects application server the company had acquired in its purchase of NeXT. The new direct sales outlet was also tied to a new build-to-order manufacturing strategy.
Microsoft deal
At the 1997 Macworld Expo, Steve Jobs announced that Apple would be entering into a partnership with Microsoft. Included in this was a five-year commitment from Microsoft to release Microsoft Office for Macintosh as well as a US$150 million investment in Apple. As part of the deal Apple and Microsoft agreed to settle a long-standing dispute over whether Microsoft's Windows operating system infringed on any of Apple's patents. It was also announced that Internet Explorer would be shipped as the default browser on the Macintosh, with the user being able to have a preference. Microsoft chairman Bill Gates appeared at the expo on-screen, further explaining Microsoft's plans for the software they were developing for Mac, and stating that he was very excited to be helping Apple return to success. After this, Steve Jobs said this to the audience at the expo:
If we want to move forward and see Apple healthy and prospering again, we have to let go of a few things here. We have to let go of this notion that for Apple to win, Microsoft has to lose. We have to embrace a notion that for Apple to win, Apple has to do a really good job. And if others are going to help us that's great, because we need all the help we can get, and if we screw up and we don't do a good job, it's not somebody else's fault, it's our fault. So I think that is a very important perspective. If we want Microsoft Office on the Mac, we better treat the company that puts it out with a little bit of gratitude; we like their software.
So, the era of setting this up as a competition between Apple and Microsoft is over as far as I'm concerned. This is about getting Apple healthy, this is about Apple being able to make incredibly great contributions to the industry and to get healthy and prosper again.
The day before the announcement Apple had a market cap of $2.46 billion, and had ended its previous quarter with quarterly revenues of US$1.7 billion and cash reserves of US$1.2 billion, making the US$150 million amount of the investment largely symbolic. Apple CFO Fred Anderson stated that Apple would use the additional funds to invest in its core markets of education and creative content.
iMac, iBook, and Power Mac G4


The original iMac
While discontinuing Apple's licensing of its operating system to third-party computer manufacturers, one of Jobs's first moves as new acting CEO was to develop the iMac, which bought Apple time to restructure. The original iMac integrated a CRT display and CPU into a streamlined, translucent plastic body. The line became a sales smash, moving about one million units each year. It also helped re-introduce Apple to the media and public, and announced the company's new emphasis on the design and aesthetics of its products.
In 1999, Apple introduced the Power Mac G4, which utilized the Motorola-made PowerPC 7400 containing a 128-bit instruction unit known as AltiVec, its flagship processor line. Also that year, Apple unveiled the iBook, its first consumer-oriented laptop that was also the first Macintosh to support the use of Wireless LAN via the optional AirPort card that was based on the 802.11b standard; it helped popularize the use of Wireless LAN technology to connect computers to networks.
Mac OS X
In 2001, Apple introduced Mac OS X, an operating system based on NeXT's NeXTstep and incorporating parts of the FreeBSD kernel. Aimed at consumers and professionals alike, Mac OS X married the stability, reliability and security of Unix with the ease of a completely overhauled user interface. To aid users in transitioning their applications from Mac OS 9, the new operating system allowed the use of Mac OS 9 applications through the Classic environment. Apple's Carbon API also allowed developers to adapt their Mac OS 9 software to use Mac OS X's features.
Retail stores
In May 2001, after much speculation, Apple announced the opening of a line of Apple retail stores, to be located throughout the major U.S. computer buying markets. The stores were designed for two primary purposes: to stem the tide of Apple's declining share of the computer market and to respond to poor marketing of Apple products at third-party retail outlets.

MAC OS

Mac OS is a series of graphical user interface–based operating systems developed by Apple Inc. for their Macintosh line of computer systems
The original operating system was first introduced in 1984 as being integral to the original Macintosh, and referred to as the "System". Referred to by its major revision starting with "System 6" and "System 7", Apple rebranded version 7.6 as "Mac OS" as part of their Macintosh clone program in 1996. The Macintosh, specifically its system software, is credited with having popularized the early graphical user interface concept.
There are two architectural legacies of Mac OS. Up to major revision 9, from 1984 to 2000, it is historically known as Classic Mac OS. Major revision 10, from 2001 to present, is branded OS X (originally referred to as Mac OS X).  Both legacies share a general interface design, and there has been some overlap of application frameworksfor compatibility; but the two systems have different origins and use deeply different architectures.
The "classic" Mac OS is characterized by its monolithic system. Versions of Mac OS up through System 4 ran only one application at a time. Even so, it was noted for its ease of use. Mac OS gained cooperative multitasking with System 5, which ran on the Macintosh SE and Macintosh II. It was criticized for its very limited memory management, lack ofprotected memory, no access controls, and susceptibility to conflicts among operating system "extensions" that provide additional functionality (such as networking) or support for a particular device. Some extensions didn't work properly together, or worked only when loaded in a particular order. Troubleshooting Mac OS extensions could be a time-consuming process of bisecting and trial and error.
The Macintosh originally used the Macintosh File System (MFS), a flat file system with only one level of folders. This was quickly replaced in 1985 by the Hierarchical File System (HFS), which had a true directory tree. Both file systems are otherwise compatible.
Files in most file systems used with DOS, Windows, Unix, or other operating systems have only one "fork". By contrast, MFS and HFS give files two different "forks". The data fork contains the same sort of information as a file in other file systems, such as the text of a document or the bitmaps of an image file. The resource fork contains other structured data such as menu definitions, graphics, sounds, or code segments that would be incorporated into a program's file format on other systems. An executable file might consist only of resources (including code segments) with an empty data fork, while a data file might have only a data fork with no resource fork. A word processor file could contain its text in the data fork and styling information in the resource fork, so that an application which doesn’t recognize the styling information can still read the raw text.
On the other hand, these forks would provide a challenge to interoperability with other operating systems. In copying or transferring a MacOS file to a non-Mac system, the default implementations would simply strip the file of its resource fork. Most data files contained only nonessential information in their resource fork, such as window size and location, but program files would be inoperative without their resources. This necessitated such encoding schemes as BinHex and MacBinary, which allowed a user to encode a dual-forked file into a single stream, or inversely take a single stream so-encoded and reconstitute it into a dual-forked file usable by MacOS.
PowerPC versions of OS X up to and including OS X v10.4 Tiger include a compatibility layer for running older Mac applications, the Classic Environment. This runs a full copy of the older Mac OS, version 9.1 or later, in an OS X process. Early New World PowerPC-based Macs shipped with Mac OS 9.2 as well as OS X. Mac OS 9.2 had to be installed by the user – it was not installed by default on hardware revisions released after the release of OS X 10.4 Tiger. Most well-written "classic" applications function properly under this environment, but compatibility is assured only if the software was written to be unaware of the actual hardware, and to interact solely with the operating system. The Classic Environment is not available on Intel-based Macintosh systems due to the incompatibility of Mac OS 9 with thex86 hardware.
Users of the classic Mac OS generally upgraded to OS X, but many criticized it as being more difficult and less user-friendly than the original Mac OS, for the lack of certain features that had not been re-implemented in the new OS, or for being slower on the same hardware (especially on older hardware), or other, sometimes serious incompatibilities with the older OS. Because drivers (for printers, scanners, tablets, etc.) written for the older Mac OS are not compatible with OS X, and due to the lack of OS X support for older Apple machines, a significant number of Macintosh users continued using the older classic Mac OS.
In June 2005, Steve Jobs announced at the Apple Worldwide Developers Conference keynote that Apple computers would be transitioning from PowerPC to Intel processors and thus dropping compatibility on new machines for Mac OS Classic. At the same conference, Jobs announced Developer Transition Kits that included beta versions of Apple software including OS X that developers could use to test their applications as they ported them to run on Intel-powered Macs. In January 2006, Apple released the first Macintosh computers with Intel processors, an iMac and the MacBook Pro, and in February 2006, Apple released a Mac mini with an Intel Core Solo and Duo processor. On May 16, 2006, Apple released the MacBook, before completing the Intel transition on August 7 with the Mac Pro. To ease the transition for early buyers of the new machines, Intel-based Macs included an emulation technology called Rosetta, which allows them to run OS X software that was compiled for PowerPC-based Macintosh models. Rosetta runs transparently, creating a user experience identical to running the software on a PowerPC machine, though execution is typically slower than with native code. Rosetta was an optional installation in OS X 10.6 Snow Leopard and is not available at all in OS X 10.7 Lion.

OS X

OS X, introduced as Mac OS X in 2001 and renamed OS X in 2012, is the latest version of Apple's operating system. Although it is officially designated as simply "version 10" of Mac OS, it has a history largely independent of the earlier Mac OS releases. Major revisions to Mac OS are now issued as point revisions, such that, for example, 10.2 is substantially different from 10.5.
The OS X architectural legacy is the successor to Mac OS 9 and the "classic" Mac OS legacy. It is however a Unix operating system, based on the NeXTSTEP operating system which Apple acquired after purchasing NeXT Computer– with its CEO Steve Jobs returning to Apple at that time. OS X also makes use of the BSD codebase and the XNU kernel. There have been twelve significant releases of OS X, the most recent being OS X 10.11, referred to as "El Capitan". Prior to 10.11 came OS X 10.10 "Yosemite", 10.9 "Mavericks", 10.8 "Mountain Lion", 10.7 "Lion", 10.6 "Snow Leopard", 10.5 "Leopard", 10.4 "Tiger", 10.3 "Panther", 10.2 "Jaguar", 10.1 ("Puma"), and 10.0 ("Cheetah").
OS X has six significant releases as OS X Server. The first of these, Mac OS X Server 1.0, was released in beta before the client version in 1999. The server versions are architecturally identical to the client versions, with the differentiation found in their inclusion of tools for server management, including tools for managing OS X-based workgroups, mail servers, and web servers, amongst other tools. As of the name change to OS X, OS X Server is no longer sold as a separate operating system product. The server tools could then be added to the singular OS X product, giving the same functionality.
OS X Server is available as an operating system to-order on Mac Mini and Mac Pro computers as a part of a server package. Unlike the client version, OS X Server can be run in a virtual machine using emulation software such as Parallels Desktop for Mac and VMware Fusion.
OS X was used as the basis for iOS, (originally iPhone OS) used on Apple's iPhone, iPod Touch, and iPad; iOS is, in turn the basis of WatchOS, used on the Apple Watch, the "Apple TV Software" on the second-generation and third-generation Apple TV, and tvOS, used on the fourth-generation Apple TV.
