You can open an app that isn’t allowed to open by manually overriding the settings in the Security & Privacy preferences.

1. In the Finder, locate the AccountEdge app.
   Most apps can be found in the Applications folder.
2. Control-click the AccountEdge app icon, then choose Open from the shortcut menu.
3. Click Open.
   The AccountEdge app is saved as an exception to your security settings, and you can open it in the future by double-clicking it, just as you can any authorised app.
