I would actually like to take issue that the Mac OS did not support multi processors. I seem to remember several machines that were multi processor from the 603e era, including one with 4 processors, if memory serves, made by one of the clone manufacturers and I believe the 8600 and 9600 were available with dual processors. These systems ran from system 8.1 to 9.2.2 with multi processor support.
