[OT] Multiple macOS recommendation sought

Several years ago - 6-8-10 years ago? Not sure when - I left VMs behind
in favor of minimally-configured actual hardware. I have a couple of
Windows laptops but almost never use them now. My main development world
consists of 4 Mac minis of various ages (all Intel or M1) and a couple
of 2015 MBP laptops (and 2 iPads). Each machine has an external drive
used by Time Machine, so I can restore my work as needed. I use Screen
Sharing to manage things on multiple computers from a single
keyboard/display/mouse and it works great for my purposes. I confess, I
don't normally reinstall the OSes except for upgrades to the next
version if needed (e.g. High Sierra to Mojave); I just keep them current
with Apple updates and have never had a dev issue that damaged the OS.
Obviously my setup doesn't cover every macOS version, but my selected
hardware+OS combos have been very adequate for my needs. And for me, it
helps to have a LAN whose physical and conceptual topologies are the
same. It helps clarify problem sources in a client/server system I maintain.
Hope this helps -
