https://github.com/pantsbuild/pants/pull/21569 deprecates running Pants on older versions of macOS, and proposes somewhat of a policy for that platform support. This is motivated by allowing us to use the free github runners, rather than needing self-hosted ones, and thus reduce costs. Summary is: • 2.24.x supports running on macOS 12, but that is deprecated • 2.25.x supports running on macOS 13 or newer (x86-64), and macOS 14 or newer (arm64) • As Apple phases operating systems out of support, so does Github, and thus, so do we Please feel to offer opinions.

I fully concur with this policy
