You are using macOS 13. We (and Apple) do not provide support for this old version. This is a Tier 3 configuration: https://docs.brew.sh/Support-Tiers#tier-3 You can report Tier 3 unrelated issues to Homebrew/* repositories! Read the above document before opening any issues or PRs.

The macOS-13 based runner images are being deprecated, consider switching to macOS-15 (macos-15-intel) or macOS 15 arm64 (macos-latest) instead. For more details see https://github.com/actions/runner-images/issues/13046
