A word of warning on this. Just because a device is technically allowed to run a given OS, doesn't mean it's going to run it as smoothly as the OS it shipped with.Just thought, because they are actively selling m1 in the air and iMac does that mean the 5 years of new os compatibility for older Mac’s starts from after it goes off sale? I.e an m1 Mac should be able to run the new Mac OS that comes out in 2028?
I've made the move many times in the past (as I suspect others have) of getting tempted by new features to keep installing new OSes on older Macs -- and then seen them gradually slow down year after year until they're "getting slow" and I end up wanting to replace them. All well and good, if you're willing to pay for new hardware to keep up with the latest features.
BUT, if you're of a mind to extend the usable lifespan of a Mac, you'd do well to be careful of how far you take the OS updates, in my opinion. One way to help with this, too, is to "overspec" the machine and buy something faster than you need today, with more RAM than you need today, to account for the increasing software overhead a few years down the road.
My own base model M1 Air is running great on Ventura and I suspect it will on Sonoma as well. But whatever OS they have in 5 years may well run kind of clunkily, if the past is any guide.
