There are various views of how the Macintosh was woken up and where the idea originated from. Although the link between the Macintosh and the Xerox PARC Alto project has been widely spoken in the historical record, early contributions Sketchpad by Ivan Sutherland and in Talian System (On-Line System) by Doug Engelbart no less importance. See History of the GUI, and Apple v. Microsoft.
Apple deliberately degrading kewujudan operating system in the early occurrence of the Macintosh to make the Macintosh look more user friendly and membezakannya than other systems such as MS-DOS, which is described as magic (arcane) and mencabar technical. Apple Macintosh mahu described as a system that "continues to function" when you turn it on.
Version
The Macintosh operating system was originally introduced as a system, such as "System 6.0.7" or "System 7". In the beginning, also known as Box Perkakasan "Toolbox", which contain adequate set piawaian routine that may be used to replace perkakasan link to the computer itself.
Justifying this Pengabstrakan Mac application written for one generation to the next generation system is used, for example: from a Mac Plus to Mac II, to the PowerBook, the Power Macintosh. In the beginning, Apple deliberately obscure kewujudan this operating system for Macs membezakan than other systems such as MS-DOS, which is described as more difficult to use compared to the Mac. Terms such as "system" and "perkakasan box (the toolbox)" is an easy way to refer to perkhidmatan Macintosh operating systems and APIs so circumvent the use of technical terms (technical jargon). So the emergence of an era G3 systems (which are recognized as the engine "new world"), a large sebahagian the physical system is stored in ROM on the main board, and also on cakera system components that add, override (override) or routine repair ROM. The goal is to circumvent the use of too much storage space in a leathery cakera terhad for system support, kerana the earliest Macs do not have a hard cakera. Actually, only one model of Mac that can run (bootable) using the ROM only, namely models of Mac Classics 1991.
System 7.5.1 is the first system to incorporate the Mac OS logo (smiling face (smiley face) blue). Mac OS 7.6 (which was issued in 1996) is the first system, called Mac OS kerana his form "clones" Mac, a similar system than other Sarekat Sarekat-like Power Computing and Motorola, and Apple wanted to tell with operasiannya is clear that the system own intellectual property rights.
Mac OS systems may dibahagikan to two types:
Mac OS "Classic", the system was originally issued for the first Mac in 1984 hinggalah Mac OS 9.
Mac OS X (the letter "X" is called ten, namely * the Roman) are more recent. Mac OS X incorporate elements of BSD Unix, OPENSTEP, and Mac OS 9. Low phase system principle, which is based on Darwin's Unix, an open source.
Mac OS Classic
Mac OS classic recognized as one system that does not have any command line (command line) is a system that uses the graphic user interface (IU) fully. Touted kerana happy to use, this system also criticized kerana using cooperative multitasking (cooperative multitasking), lack of maintenance of memory, and the tendency of additional pertelingkahan / connection. "Supplement" is perisian which added to the operating system, to provide additional functionality - such as a series of work (networking) - or endowment to certain perkakasan. Sesetengah additional connections may not function well between each other or may need to be added to follow a particular sequence. Additional resolve Mac OS may be a process that takes cuba jaya long period.
Mac OS also introduces Hierarchical File System (Hierarchical File System), as an innovative way prepare the files. One such file on DOS or Unix is jujukan stanza (bytes), which requires the application to know which ones represent the temple portion and the portion codes which represent graphs or other data, Fail Mac has two different portion. In addition to cuaran data, which is a repeat stanza, there is also the root of which contain adequate cuaran resource fork data that are constructed like menus, graphics, sound, and code segments. One such file application may only have sources that do not contain the data portion. Fail the text in the text may contain adequate data and intimation stail portion at its source, so applications that do not recognize the declaration stail still can read the text that is stored. Although kaedah has several advantages, the Mac OS can not be used alongside other operating systems that do not use the Mac OS system, for example, if something is copied instead of the Mac files to DOS or Unix, the root cuarannya discarded.
Towards the end of the 1990s, has disedari that unlicensed technology of the 1980s has been omit his life, with kewujudan multitasking operating systems new, more stable.
Mac OS X
The main plan: Mac OS X
Mac OS X mambawakan-Unix-style memory handling and pre-emptive multitasking to the Mac platform. Preparing a far better memory allows more perisian running simultaneously and virtually eliminates the possibility of something breaking down perisian perisian other. He also is a Mac OS tops include referral line, although not visible unless the user to launch perisian "terminal".
Lively interest in the Mac OS from receiving OS X, but there are some who criticize it as more difficult and less intimate than the Mac OS user's home.
Mac OS Technology
QuickDraw: pengimej imaging model of the first model gives the market a WYSIWYG lump
Finder: antaramuka to navigate the filesystem and launch applications
MultiFinder: the first version that supports running more than one simultaneous perisian
Chooser: perkakasan to reach network resources (eg, enable AppleTalk)
ColorSync: technology to ensure the appropriate color pemadanan
Handling memory Mac OS: how to arrange Mac RAM and virtual memory before the swap to the UNIX
Pengemulasian Motorola 68000 by PowerPC: how the Mac handles architectural transition than the CISC to RISC (see Mac 68K emulator)
Desk Accessories: perisian little "helpers" are allowed to be executed along with any other perisian, before the emergence MultiFinder or System 7.
PlainTalk: pertuturan synthesis technology and denunciation pertuturan
Mac-Roman: character sets
Star Trek Project
One interesting aspect of the history of Mac OS Classic is this: It is a one prototaip rahsia general unknown to earnestly Apple in 1992 code-named Project Star Trek. Matlamat this project is to create versions of Mac OS that can work on the PC-compatible Intel x86 peribadi. The project did not last long, It is canceled after only a year namely in 1993 kerana political pertelingkahan innards. Even so, this project forces triumphed make perisian like Macintosh Finder and application such as Quicktime principle function smoothly on a PC.
Although perisian Star Trek was never launched, third-party Macintosh emulators, such as vMac, Basilisk II, and Executor, finally menbolehkan possibility of running Mac OS Classic on peribadi x86 computer. Emulator, this emulator emulates terhad row 68 000 processors, and thus can not run versions of Mac OS that is more recent than the 8.1 which requires a PowerPC pemprosesor. This cutting-edge, like the Pear PC emulator has emerged that is able to emulate the PowerPC processors that are required by the latest version of Mac OS (like Mac OS X). Walaubagaimanapun, It is still in the initial ratings and such other emulator-emulator, tend to walk more slowly than the native OS.
