I'll try to reproduce and file a new issue.

Yep. This will shield the tests against resolution of `.local` addresses in `macos`.

FWIW the GHA issue on `macos-15`  [was already reported here](https://github.com/actions/runner-images/issues/12562). 

I'll await for the test results and may add the fix in #2861 as a separate commit afterwards.
