Throwing a SkippedException upon the special failure condition is just one possible suggestion. Alternatively we can also allow this as success condition.
I'm also wondering whether we should run this test with the various possibilities for SYSTEM_VERSION_COMPAT settings.

All under the assumption that we can't figure out the patch version of the macOS we run on.

Thoughts?
