             Summary: [CI][Python] Investigate using self-hosted runner for older macOS wheels
                 Key: ARROW-16835
                 URL: https://issues.apache.org/jira/browse/ARROW-16835
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Continuous Integration, Packaging, Python
            Reporter: Antoine Pitrou


Currently the {{wheel-macos-high-sierra-*}} and {{wheel-macos-mavericks-*}} packages use Github Actions runners in order to get the right macOS version.

But perhaps that could be improved by making it a two-step process?
- the expensive step, which is building the wheel, can be done on a newer macOS version if the right macOS Deployment Target is set
- the cheaper step, which is testing the just-built wheel, can be run on the desired macOS runner

That way, the very constrained execution capacity available on GHA macOS runners would be less stressed by our CI jobs.
