Is there anything preventing one from running Sierra on a 2020 MBA/MBP or 2019 16" MBP?

Asking because, should I upgrade my hardware, I have much too much software that can't run on anything beyond Sierra and I'm just not ready for $600+ of new software, several of which swapped to an $$ annual subscription from a one-time purchase, grrrrrrr.

Thank you.
 
You can’t run an OS earlier than the one that originally shipped with your model Mac. So nothing earlier than Mojave on the 2019 machine and nothing earlier than Catalina on the 2020 Mac.

You can, however, run older operating systems in virtualization. So you could install and run Sierra in Parallels on Catalina, for example.
 
Thanks, I tried answering this myself and found no help online then just now re-googled using more applicable terms and found similar info. Sorry for the wasted post, folks.

Argh AAPL you make it so dam* difficult sometimes.

Thanks, you sent me on a (productive, I think) rabbit hole for the past hour.

Stumbled upon VirtualBox.


That article got me wondering - if this appears to be a way to run OSX on a PC designed for windows, then it must not be very stable or robust since I have never seen discussion on it at macrumors or other Apple-fan sites.




I'm going to poke around more and see what's the fatal flaw besides compromised performance that prevents more from trying to "live with" OSX via VirtualBox on a windows pc (unless some kind soul can quickly share the solid answer...).
