System 1.0

System 1.0 was the very first version of the Macintosh system software, accompanying the Macintosh 128K.

It comprised of the Desktop, windows, the menu bar, icons, folders, document, applications, the Trash (Wastebasket), and system software. It could only run one application at one time. There was no colour at all.

Other points of note:


 * List view featured no icons; there was no "View by small icon" option either.
 * The icon for a floppy disk was slightly different than in later versions; the protective shutter was drawn in black on an otherwise white floppy disk.
 * The Control Panel featured almost no text labels, was very compact, and had only one pane.
 * The Open and Save dialogue boxes gave folders no recognition at all.
 * There was no Shut Down command.
 * There was no New Folder command.  There was one folder provided by default that could be duplicated if needed.
 * MFS (Macintosh File System) was the only file system format supported.  It did not support a nested directory structure.
