On January 24, 1984, Apple Computer, Inc. (now Apple Inc.) introduced the Apple Macintosh personal computer, with the Macintosh 128K model, which came bundled with the Mac OS operating system, then known as the System Software. The Macintosh is often credited with popularizing the graphical user interface. The Mac OS has been pre-installed on almost every Macintosh computer ever sold. The operating system is also sold separately from the computer. The original Mac OS was partially based on the Lisa OS, previously released by Apple for the Lisa computer in 1983, and also used concepts from the Xerox PARC Xerox Alto which Steve Jobs and several other Macintosh team members had previewed.

Early history

Development

The Macintosh project started in early 1979 with Jef Raskin, who envisioned an easy-to-use, low-cost computer for the average consumer. In September 1979, Raskin was given permission to start hiring for the project and was, in particular, looking for an engineer that could put together a prototype. Bill Atkinson, a member of the Apple Lisa team, introduced him to Burrell Smith, a service technician who had been hired earlier that year. ^[1]^[2]^[3]^[4]^[5]^[6]^[7]^[8] Jef Raskin outdoors, photographed by his son Aza Raskin. ...

In January 1981, Steve Jobs completely took over the Macintosh project. Jobs and a number of Apple engineers visited Xerox PARC in December 1979, three months after the Lisa and Macintosh projects had begun. After hearing about the pioneering GUI technology being developed at Xerox PARC from former Xerox employees like Raskin, Jobs negotiated a visit to see the Xerox Alto computer and Smalltalk development tools in exchange for Apple stock options. The final Lisa and Macintosh operating systems mostly used concepts from the Xerox Alto, but many elements of the graphical user interface were created by Apple including the menubar and pop-up menus. The click-and-drag concept was developed by Jef Raskin. Steven Paul Jobs (born February 24, 1955) is the co-founder and CEO of Apple and was the CEO of Pixar until its acquisition by Disney. ...

Unlike the IBM PC, which used 8 kB of system ROM for power-on self-test (POST) and basic input/output chores (BIOS), the Mac ROM was significantly larger (64 kB) and held key OS code. Much of the original Mac ROM was coded by Andy Hertzfeld, a member of the original Macintosh team. He was able to conserve some of the precious ROM space by interleaving some of the assembly language code. In addition to coding the ROM, he also coded the kernel, the Macintosh Toolbox and some of the desktop accessories (DAs) as well. The icons of the operating system, which represented folders and application software were designed by Susan Kare, who later designed the icons for Microsoft Windows 3.0.

Apple was very strong in advertising their newfound machine. After it was created, the company bought all 39 pages of advertisement space in the Newsweek magazine, 1984 November/December edition.

Release

The first version of the Mac OS is easily distinguished between other operating systems from the same period because it does not use a command line interface; it was one of the first operating systems to use an entirely graphical user interface. Additional to the system kernel is the Finder, an application used for file management, which also displays the Desktop. Supersedes Image:Apple_Macintosh_Desktop. ...

These releases could only run one application at a time, though special application shells such as Switcher (discussed under MultiFinder) could work around this to some extent. Systems 1.0, 1.1, and 2.0 used a flat file system with only one kludged level of folders, called Macintosh File System (MFS); its support for folders (subdirectories) was incomplete. System 2.1 (Finder 5.0) introduced the HFS (Hierarchical File System) which had real directories. System 3.0 was introduced with the Mac Plus, adding support for several new technologies including SCSI and AppleTalk, and introducing Trash "bulging", i.e., when the Trash contained files, it would gain a bulged appearance. System 4.0 came with the Mac SE and Macintosh II. MultiFinder was the name of a piece of extension software for the Apple Macintosh introduced in System 5 and featured in System 6. ...

Changes in early Macintosh operating systems are best reflected in the version number of the Finder, where major leaps are found between 1.x, 4.x, 5.x, and 6.x.

System Software 5

System Software 5 (also referred to as simply System 5) added MultiFinder, an extension which let the system run several programs at once. The system used a co-operative multitasking model, meaning that time was given to the background applications only when the running application yielded control. A clever change in system functions that applications were already calling to handle events made many existing applications share time automatically. Users could also choose to not use MultiFinder, and thus stick with using a single application at a time as in previous releases of the system software. MultiFinder was the name of a piece of extension software for the Apple Macintosh introduced in System 5 and featured in System 6. ... It has been suggested that this article or section be merged into Computer_multitasking#Cooperative_multitasking. ...

System Software 5 was also the first Macintosh operating system to be given a unified "Macintosh System Software" version number, as opposed to the numbers used for the System and Finder files.

System Software 5 was available for a very short time and only in some countries, including the United States.

System Software 6

System 7

On May 13, 1991 System 7 was released. It was the second major upgrade to the Mac OS, adding a significant user interface overhaul, new applications, stability improvements and many new features.

Year 1991 (MCMXCI) was a common year starting on Tuesday (link will display the 1991 Gregorian calendar). ... The user interface is the part of a system exposed to users. ...

The most significant feature of System 7 was probably virtual memory support, which previously had only been available as a third-party add-on. Accompanying this was a move to 32-bit memory addressing, necessary for the ever-increasing amounts of RAM available. Earlier versions of Mac OS had used the lower 24 bits for addressing, and the upper 8 bits for flags. This had been an effective solution for earlier Macintosh models with very limited amounts of RAM, but it became a liability later. Apple described code that assumed the 24 + 8-bit addressing as being "not 32-bit clean", and most such applications would crash when 32-bit addressing was enabled by the user. How virtual memory maps to physical memory Virtual memory is an addressing scheme implemented in hardware and software that allows non-contiguous memory to be addressed as if it were contiguous. ... 32-bit is a term applied to processors, and computer architectures which manipulate the address and data in 32-bit chunks. ...

One notable System 7 feature was the built-in co-operative multitasking. In System Software 6, this function was optional through the MultiFinder. System 7 also introduced aliases, similar to shortcuts that were introduced in later versions of Microsoft Windows. System extensions were enhanced, by being moved to their own subfolder; a subfolder in the System Folder was also created for the control panels. In System 7.5, Apple included the Extensions Manager, a previously third-party program which simplified the process of enabling and disabling extensions. It has been suggested that this article or section be merged into Computer_multitasking#Cooperative_multitasking. ...

The Apple menu, home only to desk accessories in System 6, was made more general-purpose: the user could now make often-used folders and applications—or anything else they desired—appear in the menu by placing aliases to them in an "Apple Menu Items" subfolder of the System Folder. AppleScript, a scripting language for automating tasks, was also introduced with System 7. 32-bit QuickDraw, supporting so-called "true color" imaging, was also included as standard; it was previously available as a system extension. TrueType, an outline font standard, was also introduced with System 7. AppleScript is a scripting language devised by Apple, Inc. ...

The Trash, under System 6 and earlier, would empty itself automatically when shutting down the computer or, if MultiFinder were not running, when launching an application. System 7 reimplemented the Trash as a special hidden folder, allowing files to remain in it across reboots until the user deliberately chose the "Empty Trash" command.

Systems 7.1 and 7.5 introduced a large number of "high level" additions, considered by some to be less well thought-out than they could have been.^{[citation needed]} Some of the most confusing were the reliance on countless System Enablers to support new hardware, and various System update extensions with inconsistent version numbering schemes. Overall stability and performance also gradually worsened during this period, which introduced PowerPC support and 68K emulation.

Stability returned with Mac OS 7.6, which dropped the "System" moniker as a more-trademarkable name was needed in order to license the OS to the growing market of third-party Macintosh clone manufacturers.

Mac OS 8

Mac OS 8 was released on July 26, 1997, shortly after Steve Jobs returned to the company. It was mainly released to keep the Mac OS moving forward during a difficult time for Apple. Initially planned as Mac OS 7.7, it was renumbered "8" to exploit a legal loophole to accomplish Jobs' goal of terminating third-party manufacturers' licenses to System 7 and shutting down the Macintosh clone market.^{[citation needed]} 8.0 added a number of features from the stillborn Copland project, while leaving the underlying operating system unchanged. A multi-threaded Finder was included, enabling better multi-tasking. The GUI was changed in appearance to a new shaded greyscale look called Platinum, and the ability to change the appearance themes (also known as skins) was added with a new control panel. This capability was provided by a new "appearance" API layer within the OS, one of the few significant changes.

Apple sold 1.2 million copies of Mac OS 8 in its first two weeks of availability and 3 million within six months. Mac OS 8.1 saw the introduction of an updated version of the Hierarchical File System called HFS Plus , which fixed many of the limitations of the earlier system (HFS Plus continues to be used in Mac OS X). There were some other interface changes such as separating network features from printing (the venerable, and rather odd Chooser was at last headed for retirement), and some improvements to application switching. However, in underlying technical respects, Mac OS 8 was not very different from System 7.

Mac OS 9

Mac OS 9 was released on October 23, 1999. It was generally a steady evolution from Mac OS 8. Early development releases of Mac OS 9 were numbered 8.7. MacOS 9 added improved support for AirPort wireless networking. It introduced an early implementation of multi-user support (though not considered a true multi-user operating system by modern standards). An improved Sherlock search engine added several new search plug-ins. Mac OS 9 also provided a much improved memory implementation and management. AppleScript was improved to allow TCP/IP and networking control. Mac OS 9 also made the first use of the centralized Apple Software Update to find and install OS and hardware updates. Some other resplendent and unique features included its on-the-fly file encryption software with code signing and Keychain technologies, Remote Networking and File Server packages and much improved list of USB drivers.

OS 9 also added some transitional technologies to help application developers adopt some OS X features before the introduction of the new OS to the public, again easing the transition. These included new APIs for the file system, and the bundling of the Carbon library that apps could link against instead of the traditional API libraries — apps that were adapted to do this can be run natively on OS X as well. Other changes were made in OS 9 to allow it to be booted in the "classic environment" within OS X. This is a compatibility layer in OS X (in fact an OS X application, known in developer circles as "the blue box") that runs a complete Mac OS 9 operating system, so allowing applications that have not been ported to Carbon to run on Mac OS X. This is reasonably seamless, though "classic" applications retain their original OS 8/9 appearance and do not gain the OS X "Aqua" appearance.

Mac OS X

While its name is similar to its predecessors from Apple, Mac OS X is largely independent.
