Mac Firewall Settings
Do you want the application "AccountEdge NE 2012.app" to accept incoming network connections?
You may see this message if you've enabled the Mac Firewall. If you plan to keep the Firewall enabled, you will want to Allow AccountEdge NE to accept incoming network connections.
Firewall settings are managed in the Security pane of your Mac System Preferences.
