I remember when the original iMac was the best selling model of computer among all brands. A title Apple retained until, IIRC, they offered multiple colour options.
MacOS was still something like 5% or so of the overall market.
Funny aside, the narrative is usually that Apple was struggling between the time Jobs left and he returned between 1984 and 1997. The truth is that their market cap was larger than Microsoft’s through 1992-93 and they were the largest or second largest computer seller around 1991-94. The bottom didn’t fall out until Windows 95 and Apple manufacturing low end computers no one wanted.
