By December 1980, Smith had succeeded in designing a board that not only used the 68000, but made it faster, bumping it from 5 to 8 megahertz (MHz) this board also had the capacity to support a 384x256 bitmap display. (The final product used a 9-inch, 512x342 monochrome display.) Bud Tribble, a Macintosh programmer, was interested in running the Lisa's graphical programs on the Macintosh, and asked Smith whether he could incorporate the Lisa's Motorola 68000 microprocessor into the Mac while still keeping the production cost down. Smith's first Macintosh board design was built to Raskin's specifications: it had 64 kilobytes (KB) of RAM, used the Motorola 6809E microprocessor, and was capable of supporting a 256x256 pixel black-and-white bitmap display.

Over the years, Raskin hired a large development team that designed and built the original Macintosh hardware and software besides Raskin, Atkinson and Smith, the team included Chris Espinosa, Joanna Hoffman, George Crow, Jerry Manock, Susan Kare, and Andy Hertzfeld. Bill Atkinson, a member of the Lisa team (which was developing a similar but higher-end computer), introduced him to Burrell Smith, a service technician who had been hired earlier that year as Apple employee number 282. In September 1979, Raskin was given permission to start hiring for the project, and he began to look for an engineer who could put together a prototype. The Macintosh project started in early 1979 with Jef Raskin, an Apple employee, who envisioned an easy-to-use, low-cost computer for the average consumer. All models of Macintosh are pre-installed with a native version of the latest Mac OS, which is currently at version 10.4 and is called 'Tiger'.

Current Macintoshes use the Intel Core and Intel Xeon 5100 series microprocessors. Apple transitioned to Intel's processor architecture in 2006, which for the first time allowed Macs to run any x86 operating system natively. Original Macintosh computers used the Motorola 68k family of microprocessors, before switching to Motorola and IBM's PowerPC range of CPUs in 1994. The first Macintosh computer, introduced in 1984, upgraded to a 512K "Fat Mac"
This is in contrast to PCs, where different brands of hardware run operating systems such as Microsoft Windows.
Production of the Macintosh is based upon a vertical integration model in that Apple facilitates all aspects of its hardware and creates its own operating system.

Macintosh systems are mainly targeted towards the home, education, and creative professional markets. The current range of Macintoshes varies from Apple's entry level Mac mini desktop, to a mid-range server, the Xserve.
It was the first commercially successful personal computer to use a graphical user interface ( GUI) and mouse instead of the then-standard command line interface. Named after the McIntosh apple, the original Macintosh was released on January 24, 1984. The Macintosh or Mac is a line of personal computers designed, developed, manufactured, and marketed by Apple Computer. Tracing the History of the Computer - Macintosh Computer
