I wrote a tutorial on how to set up DNS-over-TLS on macOS. Beware: this is kinda-hard and pretty-nerdy! https://phiffer.org/writing/dns-over-tls-on-macos/
@swiley yeah mostly just seeing how hard it was to set up, also uncertain how practical this is to actually use.
@dphiffer I'm still not convinced DNS over TLS makes a whole lot of sense (unless you want to recurse yourself which is considered rude, and even then...)
