Macintosh refers to a range of personal computers manufactured by Apple Computer, Inc. in Cupertino, California, and commonly called Macs.

The GUI operating system, originally simply refered to as the Macintosh operating system, or informally, the Mac OS, officially became the Mac OS.

Apple has been in the forefront of bringing innovations to the personal computer world by embracing new technologies in their Macintosh computers. Even though Apple didn't invent these new technologies, many of them were introduced as standard features on Macintosh which acted as a market mover as Apple created enough critical mass for after-market vendors to follow suit. For example, USB was on the shelf for quite a while until Apple made it the default keyboard, mouse and peripheral connection for the iMac, and it became widely accepted when a wave of third party USB devices followed. After Macintosh took the lead, other PC manufacturers also adopted the USB standard due to the abundance of USB devices.

PC innovations introduced or popularized by Macintosh:

  • Graphical User interface, icons, the desktop, etc.
  • Use of mouse and other pointing devices on personal computer
  • Long file names
  • PostScript Laser printer
  • Desktop Publishing
  • SCSI
  • first to make audio (both speakers and microphone) a built-in computer feature
  • spanning the window desktop over multiple monitors
  • Ethernet support comes as standard feature
  • USB, though designed for PC, but was put in popular use by Apple leading the first step.
  • firewire also known as IEEE 1394 (in PC world) or iLink (by SONY)
  • riddance of floppy drive in standard computer configuration.
  • RISC architecture
  • Aesthetic industrial design applied on Computer hardware.

Obviously, we need a lot of information here from Mac aficionados!
