Apple has a memory problem and weโre all paying for it::Apple still sells expensive โProโ computers with just 8GB of RAM and charges a fortune for more.
I would argue modern MacOS is not โbad softwareโ per se, itโs just nothing to write home about. Back in the heyday you describe, it was innovative and quite spectacular compared to the competition. Nowadays itโs rivals are better featured in many respects, but it still does everything it needs to.
