Use Case

Our macOS builds target macOS 10.14.  Support for macOS 10.14 ended three years ago.  This doesn't have much of an impact on our users or ourselves - the main consequence of targeting an outdated macOS version is that we are limited in the APIs we can use (C++ language features).

Additionally, all of our CI has moved past this target, so we're not testing on it regardless:

• Our native packages' GHA run on macos-latest (macOS 14)
• Our CI runs on macOS 11 (macOS 14 with this PR)

Users running very old macOS versions might see breakages.
