Security software

Portero is a free, open source Mac app that shows every open port and the process behind it. See what's running, kill processes on busy ports, fix 'address already in use' errors, and block ports with the built-in macOS firewall.

Portero Alternatives

Hunting down mystery ports on macOS? If Portero isn’t enough, try SpyBuster to flag risky connections, Port Manager for quick menu bar control, Portia to kill blockers in one click, Proxyman for HTTP(S) debugging, and PortTraceX to reveal why a port’s in use.
