03 / ORIGINAL ISSUE TEXT

pypa/setuptools #5105 · read the original issue

Looks like Python 3.9 on macOS is still failing because `pyobjc-framework-Metal` 12.0 doesn't provide Python 3.9 wheels. So it ends up trying to build from sdist.



`pyobjc` (transitive dependency of `jaraco.path`) could be pinned to < 12 on darwin on Python 3.9. Or if it's possible to tell tox to not use sdist (akin to https://pip.pypa.io/en/stable/cli/pip_download/#cmdoption-prefer-binary or https://docs.astral.sh/uv/pip/compatibility/#-only-binary-enforcement )
