Support

1. Make sure Capture One is running and tethered (a camera shows in its toolbar).
2. Grant permission: System Settings → Privacy & Security → Automation, find Capture Companion, and switch on Capture One.
3. If you're tethering a Canon over Wi-Fi, quit Canon's EOS Utility app — it conflicts with Capture One's wireless tether.

That's the macOS permission the Companion needs to read Capture One. Re-enable it under System Settings → Privacy & Security → Automation → Capture Companion → Capture One, then quit and reopen the Companion.

The signal and router checks only apply to a wireless tether through a supported router (GL.iNet). On a wired ("hardline") camera there's no Wi-Fi link to watch, so those parts switch off by design — the tether alarm, camera HUD and disk watch still work as normal.

Check the speaker icon in the dashboard isn't in Silent Mode (toggle with ⌃⌥⌘S), and that your Mac's output device is right. You can pick a different sound per alert type in Settings.

The guards read those values from Capture One, and not every camera brand exposes shutter/aperture/ISO over Capture One's scripting. If yours doesn't, the disconnect alarm, HUD and disk watch still work — and we'd love to hear which body you're on so we can extend support. Email us the camera model.

Right-click the menu-bar icon and choose Uninstall… — it deactivates your licence on this Mac (freeing a seat), removes the login item and its settings, and moves the app to the Trash. Prefer to do it by hand? Quit the app, drag Capture Companion from /Applications to the Trash, then deactivate the Mac from your Lemon Squeezy receipt to free the seat.
