The Mac's graphical user interface (GUI) was actually developed by Xerox and introduced on its Star workstation in 1981. Apple borrowed heavily from the Star, and subsequently, others copied the Mac, moving the GUI down the line to Windows, OS/2, Unix and Linux.The Mac interface was immediately popular with non-technical people. Instead of typing in a command to delete a file as in DOS, they could drag its on-screen icon to a trashcan. Although common today, it was a breakthrough on a personal computer in the 1980s.The Mac also used consistent menus, and Apple's guidelines for application design were generally followed by developers. In operation, the operating system was practically hidden compared to DOS, and Apple kept technical jargon to a minimum. See Macintosh and Macintosh models.
Why Didn't the Mac Overtake the PC?The Mac came out in 1984, three years after the DOS-based PC. Although its graphical interface was simple to use, and it eliminated the technical quagmire DOS users faced when adding a new device to their PCs, there were several reasons why the PC remained the predominant platform.DOS Was FasterDOS PCs were much faster. It takes much more CPU power to display graphics than text, and the early Macintosh hardware was underpowered.Apple Placed Too Much Emphasis on the MouseThe command languages that could automate myriad tasks in DOS were absent in the Mac, which was very unappealing to the technical staff. In addition, Apple overemphasized the mouse and gave little attention to essential keyboard commands, hardly a way to gain acceptance in the business world where keyboard-intensive word processing was the largest application at the time. Today, more than three decades later, mouse movement and clicking are still required in macOS to complete many actions where pressing one or two keys would be faster.However, Mac applications were eventually enhanced, and speed was dramatically increased, but the DOS world was too entrenched by the time those improvements came. Windows 3.0, which offered a graphical interface with many of the Mac's advantages, ran as an extension to DOS and was its natural successor. Windows 95 added more features, and by that time, the world was buying Windows.Macs Cost MoreThe Mac was always pricier than a PC, which purchasing agents found hard to justify. Although many employees bought their own Macs due to their aversion to PCs, technical personnel were not fond of supporting them. They sweated bullets dealing with DOS and Windows, and one more platform was not met with enthusiasm.Proprietary TechnologyUnlike the PC, the Mac is Apple's proprietary technology, and except for one brief period, there is no Mac-compatible industry (see Macintosh clone). Apple maintains its sole source status while the PC industry has numerous vendors.In SummaryAs a result of these combined factors, the Mac was used sporadically in the corporate world but became popular in desktop publishing and graphic design. It became the de facto standard in graphics arts.Apple moved to Intel chips in 2006, and since then, many Windows users switched to Macs. With the Mac's ability to run Windows applications, but primarily due to the increasing use of platform-independent Web applications, Mac usage expanded. As of 2019, the Mac has approximately a 10% global personal computer market share.
