Macintosh system} {platform} manufactured by {Apple Computer, Inc.}, originally based on the {Motorola 68000} {microprocessor} family and a proprietary {operating system}. The Mac was Apple's successor to the {Lisa}. The project was proposed by {Jef Raskin} some time before {Steve Jobs}'s famous visit to {Xerox PARC}. Jobs tried to scuttle the Macintosh project and only joined it later because he wasn't trusted to manage the {Lisa} project. The {Macintosh user interface} was notable for popularising the {graphical user interface}, with its easy to learn and easy to use {desktop} metaphor. The {Macintosh Operating System} is now officially called Mac OS. The first Macintosh, introduced in January 1984, had a {Motorola 68000} {CPU}, 128K of {RAM}, a small {monochrome} screen, and one built-in {floppy disk} drive with an external slot for one more, two {serial ports} and a four-voice sound generator. This was all housed in one small plastic case, including the screen. When more memory was available later in the year, a 512K Macintosh was nicknamed the "Fat Mac." The standard Macintosh screen {resolution} is 72 {dpi} (making one {point} = one {pixel}), exactly half the 144 dpi resolution of the ancient {Apple Imagewriter} {dot matrix} printer. The Mac Plus (January 1986) added expandability by providing an 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}, an optional built-in 20 megabyte hard disk and one internal expansion slot for connecting a third-party device. The Mac II (March 1987) used the faster {Motorola 68020} {CPU} with a 32-bit {bus}. In 1994 {PowerPC} based Macs, {Power Macs}, were launched, and in 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 G5 Power Mac was released, the first Mac to be based on a 64-bit architecture. {IBM} and not Motorola manufactured the CPU for this new generation of Power Macs. The clock speed was initially 1.6GHz but a dual 2GHz system was available in September. Mac OS X is the successor to Mac OS 9, although its technological parent is the {NEXTSTEP} OS from {Next, Inc.}, founded by Steve Jobs after he left Apple the first time. OS X is based largely on the {BSD} UNIX system. The core of the OS X operating system is released as free {source code} under the 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 true for Mac OS 9, and totally incorrect for Mac OS X, which has protected memory, so even if one application crashes, the system and other applications are unaffected.
