Yeh I get it... my wandering thoughts were off a bit lolIt wasn't, though. Big Sur is (at this time), although it continues Catalina's downward slide. And no one knows whether or not the successor to Big Sur will be ARM-only or not at this point.
2020 Intel hardware came with Catalina installed (and no backward compatibility with Mojave, which I would have preferred installing) - that's what I meant by "final" Intel processor release.
Either way, my stuff running on Catalina will be fine for now and if they kill support and updates before US guvt guidelines which they've sort of followed in the past so be it.
