STINNER Victor <vstinner@redhat.com> added the comment: Ronald, Ned: What is the macOS version used to build Python binaries distributed on python.org? Do we get the constant on macOS 10.12 if binaries are built on macOS 10.11 for example? I guess that people building Python from source like hombrew will get the constant. Joannah: Can you please convert attached patch into a pull request? Please mention Ricardo Fraile as co-author of the change (mention his name in the commit message).
