Given the low amount of resources we have to work on GDB for macOS and 
the fact that it's difficult for one person to test on different 
versions of macOS (you would need multiple Mac computers, AFAIK), I 
suggest that we only aim at supporting the last two released versions of 
macOS.  I say two, because there will always be an overlap after a new 
version is released, where some people use the new version and others 
have not upgraded yet.

If some people use older versions of macOS and want to contribute 
patches and help testing, that's fine too, but if everybody contributing 
is on latest or latest-1, we can't realistically ensure it works on 
previous versions.

That said, I agree that it would be very helpful if commit messages and 
comments in the code mentioned the version of macOS that was used at the 
time that commit message or comment was written.
