MacintoshMacintosh(computer)The project was proposed by Jef Raskin some time beforeSteve Jobs's famous visit to Xerox PARC. Jobs tried toscuttle the Macintosh project and only joined it later becausehe wasn't trusted to manage the Lisa project. The Macintosh user interface was notable for popularisingthe graphical user interface, with its easy to learn andeasy to use desktop metaphor. The Macintosh Operating System is now officially calledMac OS. The first Macintosh, introduced in January 1984, had aMotorola 68000 CPU, 128K of RAM, a small monochromescreen, and one built-in floppy disk drive with an externalslot for one more, two serial ports and a four-voice soundgenerator. This was all housed in one small plastic case,including the screen. When more memory was available later inthe year, a 512K Macintosh was nicknamed the "Fat Mac." The standard Macintosh screen resolution is 72 dpi (makingone point = one pixel), exactly half the 144 dpiresolution of the ancient Apple Imagewriter dot matrixprinter. The Mac Plus (January 1986) added expandability by providingan external SCSI port for connecting hard disks, magnetic tape, and other high-speed devices. The Mac SE (March 1987) had up to four megabytes of RAM, anoptional built-in 20 megabyte hard disk and one internalexpansion slot for connecting a third-party device. The Mac II (March 1987) used the faster Motorola 68020 CPUwith a 32-bit bus. In 1994 PowerPC based Macs, Power Macs, were launched, andin 1999, the iMac, updated on 2002-01-07. The Power Mac G4(Quicksilver 2002) was the first Power Mac to clock at 1GHz and"Superdrives" (combined DVD-ROM, DVD-RW, CD-ROM, CD-RW)appeared in the iMac in 2002. In mid 2003 the first G5Power Mac was released, the first Mac to be based on a 64-bitarchitecture. IBM and not Motorola manufactured the CPU forthis new generation of Power Macs. The clock speed wasinitially 1.6GHz but a dual 2GHz system was available inSeptember. Mac OS X is the successor to Mac OS 9, although itstechnological parent is the NEXTSTEP OS from Next, Inc.,founded by Steve Jobs after he left Apple the first time. OSX is based largely on the BSD UNIX system. The core of theOS X operating system is released as free source code underthe project name Darwin. If "Macintosh" were an acronym, some say it would stand for"Many Applications Crash, If Not, The Operating System Hangs".While this was true for pre Mac OS 9 systems, it is less truefor Mac OS 9, and totally incorrect for Mac OS X, which hasprotected memory, so even if one application crashes, thesystem and other applications are unaffected. See also Macintosh file system, Macintosh user interface. Apple Home. MacintoshA family of desktop and laptop computers from Apple, introduced in 1984. First to popularize the graphical user interface (GUI), the combination of Mac hardware and software has provided an ease of use that users have very much enjoyed over the years.It has essentially been a Mac vs. Windows world for personal computers. However, Google's Chrome computer has gained ground in the education market (see Chromebook). See Windows vs. Mac. Because Macintoshes were commonly called "Macs," Apple later changed the brand officially to "Mac." For an overview of the line, see Macintosh models. To learn about the Mac's origins, see Macintosh history. Hardware Evolution The first Macs were powered by Motorola's 32-bit 68K family of CPUs. In 1994, Apple introduced the Power Macs, which used the higher-performance PowerPC chip designed by Apple, Motorola and IBM. Power Macs ran native PowerPC applications and emulated traditional Mac 68K applications. Over the years, PowerPC chips provided substantial increases in performance. In 2006, Apple began to switch the Mac line to the same Intel x86 CPUs used for Windows PCs. The iMac desktop and MacBook Pro laptop were the first to use them (see Mactel). As a result, Macs can run Windows natively or simultaneously (see Boot Camp, Parallels Desktop and VMware Fusion). Prior to the Intel switch, Windows and DOS applications could run in a Mac using an emulator (see Virtual PC for Mac). See Macintosh clone, Mac OS X, G3, G4, G5, HFS and Apple.
MacintoshMacintoshApple’s seminal product that revolutionised the computing industry by incorporating a GUI interface in the operating system. The first primitive Mac, produced in 1984, had the same basic elements now considered standard for all PCs—e.g., software formats like “pull-down” menus, “point-and-shoot” commands, and icons to represent files, programs and landmarks on the desktop, as well as hardware elements such as a mouse to navigate through the software and straightforward screen displays. Macs and modern PCs are “user friendly”, designed so that technologically unsophisticated consumers are able to use computers without the need to understand their internal workings.macintosh
