Uh, think you need to recheck. Mac was released in 1984, Windows 1.0 was release in 1985.
Apple provided Microsoft the code for MacOS so Microsoft could code Word, Multiplan (later called Excel, and File (was a simple database that died) to be released when the Mac was in 1984. Windows 1.0 was a GUI extension for DOS. MacOS was a complete operating system. Apple actually got permission from Xerox to use the window based interface using the mouse, and ethernet (which Apple called Appletalk) from Xerox-Parks because Xerox thought it had nothing to do with copiers.

Used various computers since 1976 and our HS's terminal access to the school systems main frame. My brother got an AppleII in 1977 and I used it and later one at work. Did not get my own computer until 1984. Got an Appleiic because it did color and the new Mac did not. It was also easier to program using Applesoft Basic, and Microsoft's Assembly Language Compiler for AppleII. The language for the first macs was Pascal.

In 1986 switched over to a mac because it did WYSIWYG for typesetting and could just take my pagemaker file to the typesetters, and get a layed out page of type, no more cut and paste on the drawing board. There was also an emulator that I could run all my AppleII software on the mac.
