This gives you that beautiful green lock in Chrome. I'm assuming you're putting your SSL documents in /etc/ssl, but you can put them anywhere and replace the references in the following commands. Tested successfully on Mac OS Sierra and High Sierra.

Set up localhost.conf

sudo nano /etc/ssl/localhost/localhost.conf
