You can also code in a language with good cross platform network APIs like Go or use a wrapper library like boost::asio or libuv. The latter are likely to add support for this eventually if there is a strong benefit to doing so on MacOS. I'm ambivalent about platform-specific solutions but I welcome any attempt to obsolete socket() and select()/poll() and friends. I absolutely loathe that API.
