Once dnscrypt-proxy is running, you will have to update your local
DNS server to point to 127.0.0.1 in order for it to actually work.
This is generally done under System Preferences > Network > Advanced.
Once there, you will see a "DNS" tab where you can enter a list of DNS
servers. You will want to make sure that 127.0.0.1 is listed there first.
Note: By default, dnscrypt-proxy runs on 127.0.0.1:53 under the "nobody" user.
If you would like to change these settings, you will have to edit the plist file.
To check that dnscrypt-proxy is running properly, open Terminal and enter this at
the command prompt:
nslookup -type=txt debug.opendns.com
You should see something like this in the output:
debug.opendns.com text = "dnscrypt enabled (...)"
