How to determine what process is listening on OSX

Question

Trying to help configure Laravel Valet on a Mac running El Capitan, and the user had installed MAMP previously. MAMP is disabled but anytime we load a valet address (mysite.dev) we get a standard Apache 404 page.

Is there a way to determine what process is listening on port 80 and conflicting with Valet so I can disable it?

You can hopefully adapt this one https://stackoverflow.com/a/24388281/2836621 — Mark Setchell, Nov 11 '17 at 17:13

See Who is listening on a given TCP port on Mac OS X?

lsof -n -i4TCP:80 | grep LISTEN

Or some such.

Omitting `:80` will show all processes that are listening. – neevek Jul 06 '18 at 16:35
