Portero
macOS tool for viewing ports, managing processes, and blocking ports
About Portero
Portero is a macOS port management tool that provides a centralized view of running services and the ports they use. It automatically refreshes listening TCP and UDP ports and shows the process, PID, address, user, and start time; after confirmation, you can gracefully stop or force-terminate one or multiple processes, and use the built-in macOS firewall to block inbound or outbound traffic on any port.
