Mac OS X brought Unix-style memory management and pre-emptive multitasking to the Mac platform. The Classic OS is still supported and Classic Applications Support was shipped in addition to OS X with PowerPC (but not Intel) Macs until early 2006. On the other hand, these forks provided a challenge to interoperability with other operating systems copying a file from a Mac to a non-Mac system would strip it of its resource fork. A text file could contain its text in the data fork and styling information in the resource fork, so that an application which didn't recognize the styling information could still read the raw text. A file might consist only of resources with an empty data fork, or only a data fork with no resource fork.

The resource fork contained other structured data such as menu definitions, graphics, sounds, or code segments. The data fork contained the same sort of information as other file systems, such as the text of a document or the bitmaps of an image file. By contrast, MFS and HFS gave files two different "forks". Most file systems used with DOS, Unix, or other operating systems treat a file as simply a sequence of bytes, requiring an application to know which bytes represented what type of information.

Its low-level BSD-based foundation, Darwin, is free software/open source software. Mac OS X incorporates elements of OpenStep (thus also BSD Unix and Mach) and Mac OS 9.

Mac OS depended on this core system software in ROM on the motherboard, a fact which later helped to ensure that only Apple computers or licensed clones (with the copyright-protected ROMs from Apple) could run Mac OS. A fatal software error, or even a low-level hardware error discovered during system startup (such as finding no functioning disk drives), was communicated to the user graphically using some combination of icons, alert box windows, buttons, a mouse pointer, and the distinctive Chicago bitmap font. (Only one model of Mac was ever actually bootable using the ROM alone, the 1991 Mac Classic model.) This architecture also allowed for a completely graphical OS interface at the lowest level without the need for a text-only console or command-line mode. The initial purpose of this was to avoid using up the limited storage of floppy disks on system support, given that the early Macs had no hard disk. Until the advent of the later PowerPC G3-based systems, significant parts of the system were stored in physical ROM on the motherboard. System 7.5.1 was the first to include the Mac OS logo (a variation on the original "Happy Mac" smiley face Finder startup icon), and Mac OS 7.6 was the first to be named "Mac OS" (to ensure that users would still identify it with Apple, even when used in "clones" from other companies). The early Macintosh operating system initially consisted of two pieces of software, called "System" and "Finder", each with its own version number. Most recently, Mac OS X has become compatible with Intel's x86 architecture. As Apple introduced computers with PowerPC hardware, the OS was upgraded to support this architecture as well. As increasing disk storage capacity and performance gradually eliminated the need for fixing much of an advanced GUI operating system in ROM, Apple explored cloning while positioning major operating system upgrades as separate revenue-generating products, first with System 7 and System 7.5, then with Mac OS 7.6 in 1997.Įarlier versions of the Mac OS were compatible only with Motorola 68000-based Macintoshes. Much of this early system software was held in ROM, with updates typically provided free of charge by Apple dealers on floppy disk.

The original form of what Apple would later name the "Mac OS" was the integral and unnamed system software first introduced in 1984 with the original Macintosh, usually referred to simply as the System software.Īpple deliberately downplayed the existence of the operating system in the early years of the Macintosh to help make the machine appear more user-friendly and to distance it from other operating systems such as MS-DOS, which were portrayed as arcane and technically challenging.

The Macintosh user experience is credited with popularizing the graphical user interface. (formerly Apple Computer, Inc.) for their Macintosh line of computer systems.

Mac OS is the trademarked name for a series of graphical user interface-based operating systems developed by Apple Inc.
