How to view and remove routes on macOS

Today I needed to remove a bad route on macOS. Normally I just reboot to do that, but I decided to learn how to do it without rebooting.

Here’s how I did it.

First, view the routes to confirm the route is bad:

netstat -rn | grep IP_ADDR

Grab the IP you care about from the “Destination” column. Use it to delete the route:

sudo route -n delete DEST_IP_ADDR

Done!
