<Tr> <Th> Operating system </Th> <Td> Macintosh operating systems (Classic Mac OS macOS) </Td> </Tr> <Tr> <Th> Website </Th> <Td> www.apple.com/mac </Td> </Tr> <P> The Macintosh (/ ˈmækɪnˌtɒʃ / MAK - in - tosh; branded as Mac since 1998) is a family of personal computers (PCs) designed, developed, and marketed by Apple Inc . Steve Jobs introduced the original Macintosh computer on January 24, 1984 . This was the company's first mass - market personal computer featuring an integral graphical user interface and mouse . This first model was later renamed to "Macintosh 128k" for uniqueness amongst a populous family of subsequently updated models which are also based on Apple's same proprietary architecture . Since 1998, Apple has largely phased out the Macintosh name in favor of "Mac", though the product family has been nicknamed "Mac" or "the Mac" since the development of the first model . </P> <P> The Macintosh was expensive, which hindered its ability to be competitive in a market already dominated by the Commodore 64 for consumers, as well as the IBM Personal Computer and its accompanying clone market for businesses . Macintosh systems still found success in education and desktop publishing and kept Apple as the second - largest PC manufacturer for the next decade . In the 1990s, improvements in the rival Wintel platform, notably with the introduction of Windows 3.0, then Windows 95, gradually took market share from the more expensive Macintosh systems . The performance advantage of 68000 - based Macintosh systems was eroded by Intel's Pentium, and in 1994 Apple was relegated to third place as Compaq became the top PC manufacturer . Even after a transition to the superior PowerPC - based Power Macintosh (later renamed the Power Mac, in line with the PowerBook) line in 1994, the falling prices of commodity PC components and the release of Windows 95 saw the Macintosh user base decline . </P>
