Configuration
Open the menu-bar icon → Settings….
Every Ethernet-type interface is listed. Physical adapters are on by default (opt-out) —
any new real adapter you plug in is automatically used as a trigger. Virtual adapters
(bridge / VPN / VM, e.g. VMware vmnet, Parallels, tunnels) are off by default (opt-in)
and tagged virtual, so they can't accidentally pin Wi-Fi off forever. Tick one to opt it in.
Wi-Fi turns off when any enabled wired interface has an active link.
Every Wi-Fi interface is listed; all are controlled by default. Untick any you don't want LanGuard to touch.
Toggle Show notifications when Wi-Fi toggles. macOS will ask for notification permission on first launch — click Allow for banners to appear.
Pick how the indicator looks:
-
Icon only —
cable.connector(LAN) /wifi/pause.circle(Off) -
Icon + label — icon plus
LAN/Wi-Fi/Off - Label only — text
In the menu, Auto-toggle Wi-Fi disables all automatic action. While off, LanGuard never
changes Wi-Fi — the icon shows Off/pause.
Toggle in Settings. LanGuard uses SMAppService; it re-registers automatically if the app
moves and prompts you if macOS requires approval (System Settings → General → Login Items).
