What technology does it require? If T2, then why isn't the 2018 Mac mini supported? Seriously, this list is incredibly small and restrictive. And aside from this specific point, an end user is FAR more likely to have a combination of new and old Macs, than all new Macs. Thus, I would argue, that for most end users this is going to be of very limited use, and, to a large extent, confusing, when it works for some pairings and not others.
Apple should have made it dependent on macOS version. At least that way, a user could easily recognise *why* it does or doesnt work on a given computer. As it is, the list looks completely arbitrary.
