Apple did not (at least early in the Mac's life), publish anything beyond what was needed for writing the 'standard' interfaces. I don't know this fromn direct experience, but from the comments and anguished screaming I heard from people trying to do anything a little out of the gospel ways as laid down by Apple. The whole machine is like that from what I can see. Closed software, closed hardware, and only recently has Apple decided that perhaps the users might be better able to judge what they really want, and have allowed for expansion in at least one of their machines.
