Not at all. The first graphical operating system was on the Xerox Alto workstation.
The Xerox Alto was an experimental form of what would now be called a "networked desktop computer." It was developed in the Xerox Palo Alto Research Center before the IMB PC or Apple I hit the market. Xerox deployed the Alto in many of its manufacturing and research locations, as well as within Ginn and Company, a book publisher that was then a Xerox subsidiary. However, the Alto was never offered in the commercial market. The Xerox 6085 (Xerox Star), using using a graphical user interface and operating system ultimately called GlobalView, was derived from the Alto and was eventually offered in the commercial market. It was unable to compete with the less costly PC and Apple Macintosh and was eventually discontinued.
The Xerox Alto was made by Xerox Corporation at its Palo Alto Research Center in Palo Alto, California.
Xerox Alto was created in 1973.
The Xerox Alto was developed in 1973 at the Xerox Palo Alto Research Center (PARC) in California . The name "Alto" came from the location, Palo Alto. The Alto was a development machine and was not marketed. However, machines based upon the Alto were eventually offered in the marketplace.
Probably the Xerox one for their experimental prototype Alto computer workstation. That inspired Jobs and Wozniac of Apple to make the one on the Lisa, then the Macintosh.
After Mac OS. Mac OS was based on the earlier Xerox Alto system.
