Mux: Auto Network Switch

Mux monitors the network interfaces on a Mac and automatically switches between them according to a user‑defined priority list. When an Ethernet cable is connected, the application disables Wi‑Fi and re‑enables it when the cable is removed, applying the same logic to other interfaces such as Thunderbolt Bridge or Hotspot. Users can set schedules, adjust the delay before a switch (3 s, 5 s, 10 s), and view a concise log of every change in the menu bar.

The tool is aimed at Mac users who want their machine to stay on the most appropriate network without manual intervention, especially in environments where multiple connections are available and reliability matters. It provides a single pane for reordering, enabling, or disabling network services, and respects privacy by keeping all detection and logging on the local device via standard macOS APIs.

Distinctive aspects include instant response to network events, a configurable priority system, and the ability to run silently in the background while presenting status and logs in a compact interface. The application is offered as an experimental, free‑trial download with optional paid licenses for additional Macs.
