From The Free On-line Dictionary of Computing (18 March 2015) :

  Mac
  
      The line of computers manufactured by Apple Inc.
     "Mac" is not primarily a nickname or an abbreviation, but a
     brand name and trademark in its own right.  Apple currently
     (2009) refer to the brand as any of "Mac", "iMac" or
     "Macintosh" (all registered trademarks).
  
     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 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 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 the Power Mac was launched, and in 1999 the iMac
     was introduced.  The SuperDrive appeared in the iMac in 2002.
  
     The Macintosh Operating System is now officially called "Mac
     OS".  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.
  
     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.
  
     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.
  
     See also Macintosh file system, Macintosh user interface.
