Dirk,
the minimum required version for the high-sierra build is 10.13 and for big-sur
build is 11.0 (as the names imply). Although it is not unrealistic to move
Intel to macOS 10.14, it would be more problematic to move to 10.15 since it is
the version that killed 32-bit support so 10.14 is actually more prevalent than
10.15 as a lot of users will never upgrade due to that loss. Given that Intel
binaries are there only to support legacy hardware it's unlikely to move
forward much more (i.e. I can see the immediate argument saying that those
macOS version are unsupported, but so are the machines running them, but that
doesn't mean R users won't use them).
What exactly do you need the higher macOS versions for? Generally, there were
no major changes in the Mach-O format recently, so it shouldn't really matter -
the main difference would be SDK/run-time - are there specific features you
require? Some of it could be addressed by providing more recent run-times
separately - that's why I'm asking.
Cheers,
Simon
