From Walter Isaacson's Steve Jobs, the Mac was initially called Annie:
One of Raskin’s dreams was to build an inexpensive computer for the masses, and in 1979 he convinced Mike Markkula to put him in charge of a small development project code-named “Annie” to do just that. Since Raskin thought it was sexist to name computers after women, he redubbed the project in honor of his favorite type of apple, the McIntosh. But he changed the spelling in order not to conflict with the name of the audio equipment maker McIntosh Laboratory. The proposed computer became known as the Macintosh.
Today I learned that a guy named Jef Raskin was the biological father of what we know now as Mac.
In various interviews, Jobs had been referring to computers as a bicycle for the mind; the ability of humans to create a bicycle allowed them to move more efficiently than even a condor, and likewise the ability to create computers would multiply the efficiency of their minds. So one day Jobs decreed that henceforth the Macintosh should be known instead as the Bicycle. This did not go over well. “Burrell and I thought this was the silliest thing we ever heard, and we simply refused to use the new name,” recalled Hertzfeld. Within a month the idea was dropped.
Thank God there were people who dared to stand up to Steve for his silly decisions.
