On some macOS setups, wg-quick up
does not work correctly if the Wireguard configuration includes a DNS server address.
When this error occurs, wg-quick up
exits with the following lines, and the Wireguard tunnel will not work:
$ sudo wg-quick up wg0
...
[#] rm -f /var/run/wireguard/utun3.sock
[#] rm -f /var/run/wireguard/wg0.name
