Private Eye

It provides a firewall and real‑time network monitor for macOS, allowing users to see every outbound connection made by applications and to block any app from accessing the internet with a single click. The interface lists both visible applications and hidden helpers such as daemons, XPC services and background processes, giving a clear view of which software is “phoning home.”

The tool is designed for macOS 10.15 or newer and runs on both Apple Silicon and Intel Macs. Installation is described as taking less than a minute, and the firewall operates invisibly without persistent windows, pop‑ups, or menu‑bar icons, aiming to have minimal impact on system performance.

It targets users who want a simple, low‑maintenance way to protect privacy and control network traffic without needing deep networking expertise. The software is positioned as a lightweight, user‑friendly alternative to more complex firewalls.
