Or in my case, a 2012 MacBook Air. I hope they'll support Catalina for another three or four years or at which point it's more than a decade old and can finally mature into a laptop's final stage of life as a Linux machine.
I stand corrected. I'd attribute my false confidence to the fact that even the previous version (macOS 10.4 Mojave) is still supported. But now that I think about it that'll likely change at the Apple WWDC in June.
Still, decently satisfied with ~10 years of software support for a laptop.
Mojave Support ends this year right on time for 3 years. I finally left Mojave behind myself as I really wasn't using the older apps catalina lost support for anyway.
