On #354 we got MacOS CI working in the presence of an XCode 14 linker bug by downgrading to MacOS 11. As discussed at actions/runner-images#6350, we can stay on MacOS 12 but force XCode 13.4 (non-buggy).
Also, it's not a bad idea or a bad time to use Python 3.9 for CI (we have been using 3.8, which is now in a 'security fixes only' phase).
Note that if/when this PR is accepted, I'll switch the required builds in the branch-protection rules for this repo to require 3.9 passes rather than 3.8 (as now).
