While cibuildwheel can build CPython 3.8 universal2/arm64 wheels, we cannot test the arm64 part of them, even when running on an Apple Silicon machine. This is because we use the x86_64 installer of CPython 3.8. See the discussion in https://github.com/pypa/cibuildwheel/pull/1169 for the details. To silence this warning, set `CIBW_TEST_SKIP: "cp38-macosx_*:arm64"`.

You are using macOS 12. We (and Apple) do not provide support for this old version. It is expected behaviour that some formulae will fail to build in this old version. It is expected behaviour that Homebrew will be buggy and slow. Do not create any issues about this on Homebrew's GitHub repositories. Do not create any issues even if you think this message is unrelated. Any opened issues will be immediately closed without response. Do not ask for help from Homebrew or its maintainers on social media. You may ask for help in Homebrew's discussions but are unlikely to receive a response. Try to figure out the problem yourself and submit a fix as a pull request. We will review it but may or may not accept it.
