read about jeff raskin
He said that during the process of making the macintosh, they had built a serial board and a program that could use the mouse. So the mouse was originally designed for the Mac. which first went into the Lisa because the mac hadn't shipped yet.
During the development, they figured out how to get the 6502 in the Apple II to display non-laggy feedback from the mouse. They used the Apple II to boot the Mac through the serial port.
However, to design the finder, they did it through the Apple II, running the GUI on the Apple II (which probably had the Apple II desktop OS come out after the Mac)
Also, another bit of trivia, the Mac 128k was originally going to use the 6502, but they found out it wasn't powerful enough. So they chose the new up-and-coming 68k
