Description
The macOS specialization for NetworkMonitor does not support the NO_CARRIER state, while the implementation for netlink (Linux) does. The current implementation on macOS can therefore not distinguish between interfaces that are administratively up, but disconnected from those that are administratively down.
Per #3817-18, this will likely require that the macOS NetworkMonitor specialization be rewritten to use the lower-level PF_SYSTEM/SYSPROTO_EVENT socket API instead of SCDynamicStore API, since the latter does not notify when interface flags (where this information comes from) change.

I don't have straightforward access to a Mac machine to work on this issue at this time.
