macOS failing on main

[jakirkham]

Looks like the recent merge into main is failing on macOS CI. As the PR ( #321 ) was passing before, maybe this is due to old logic macOS 10.9 logic that needs a refresh for macOS 10.13 ( conda-forge/conda-forge.github.io#1844 ), which is the minimum macOS version

Hi! This is the friendly automated conda-forge-webservice.

I just wanted to let you know that I started rerendering the recipe in #327.
