A button that does nothing is usually a missing permission. The action ran, but it had no permission to do its work, so nothing visible happened and no error appeared.
Start with Diagnostics
- On the Mac, click the Treadle icon in the menu bar.
- Open
Diagnostics. - It shows which permission is missing and the fix.
After you grant Accessibility, let the engine restart so the change takes effect. That restart is normal. For what each permission is for, see permissions.
Other causes
- The app the action targets is not installed. Install it, or point the control at an app you have.
- A helper tool the action needs is not installed.
- The iPad is disconnected. Check that it still reaches the Mac; see The iPad can't find my Mac.
- The engine has stopped. Open the menu-bar popover and choose
Restart engine. See the concepts page for what the engine is.
For custom commands and Shortcuts
- A custom command may fail if a tool it relies on is missing. Check it runs on its own in a terminal. See Write your own command.
- A Shortcut may fail if it does not run on its own. Test it in Apple's Shortcuts app. See Use a Shortcut as an action.
If a button still does nothing after all of this, email support@gettreadle.ca.
