For what it is worth mac + avid were a piece of crap in the nineties if you talk about non-linear video editing (an expensive setup with lots of issues). Only reasonable for the mac fan boys.
More expensive, but undoubtely high-end were Silicon Graphics options. They were the undisputed king of the hill.
Everyone else was trying to mimic or take some market share from them.
The Amiga and the Video Toaster were undisputed in another segment: analog video.
Two different stories, two different market segments.
