That's a problem when passing in low-level information from a system running a different version of macOS (for example passing in the low-level version information from a macOS 10.8 system while the script is running on a macOS 10.14 system).
I abandonned my PR 11187 and I wrote PR 11207 to add a comment explaining why Darwin is not replaced with macOS.
Well, use platform.platform() or platform.mac_ver() to get the macOS version ;-)
