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.
