PortInspector
macOS menu-bar utility
See what’s listening on your local ports and kill the owning process in one click. A lightweight native menu-bar app — no Dock icon, no clutter, just a popover with a live, filterable list of active TCP/UDP ports.
- Live list of ports with process, PID & state
- One-click kill — SIGTERM, then force SIGKILL
- Only signals processes you own — never root
