Help, when you need it.

If fadr keeps asking for Accessibility permission after you granted it, quit fadr, open System Settings → Privacy & Security → Accessibility, toggle fadr off and on, then relaunch.

BTT gestures that start in the middle of the trackpad rarely conflict. If you have BTT gestures set to begin at the edges, open fadr Preferences → Edges → Edge margin and lower it, or assign that edge to None.

Open Preferences → Edges and confirm the edge has an action assigned. Check Typing detection - if you just typed, fadr waits a few hundred milliseconds before re-arming. Finally, rebooting the app often clears up stale gesture state.

Plug in via Lightning once to pair, then fadr will recognize it over Bluetooth. If you use multiple trackpads, assign edges per-device in Preferences → Devices.

Make sure you're using the most recent version of fadr. Paste the key exactly as it appears in your purchase email (no extra spaces). If you still get an error, email the key to us and we'll fix it manually.

Quit fadr, drag it from Applications to the Trash, then remove ~/Library/Preferences/llc.valid.fadr.plist if you want to erase your settings too. Revoke Accessibility permission under System Settings → Privacy & Security.
