Apple Macintosh can be considered the very first commercially successful computer to use a GUI (Graphical User Interface).
After uncertain beginnings, it met with great success despite having no hard disk, single-sided floppy disks, no expansion slot and very little memory, but it was a very attractive alternative to PC compatibles and their old MS-DOS, and text-based applications. Soon it arrived on the market Macintosh 512 (the same but with 512 KB RAM) then replaced by the Macintosh Plus.
The first Operating System was called ‘Macintosh System 1.0′. Apple contineud to call its operating systems like this until the System 7. After that it changed the name to ‘Mac OS’. The System/Finder suite was designated ‘Macintosh System Software 0.0.’. It wasn’t until System 6 that the System file version and System Software designation coincided.
