This can be avoided by upgrading to a version of the app that is signed by its developer. For Outlook for Mac users, the pin is available in version 13 and later. Instead, the "Allow or Deny" dialogue appears every time the app is opened. If the firewall recognises such an app, it doesn't sign it. Some apps check their own integrity when they are opened without using code signing. If you want to deny a digitally signed application, you should first add it to the list and then explicitly deny it. If you choose Deny, OS X adds it to the list but denies incoming connections intended for this app. If you choose Allow, OS X signs the application and automatically adds it to the firewall list.


If you run an unsigned app that is not listed in the firewall list, a dialogue appears with options to Allow or Deny connections for the app. Apps included in OS X are signed by Apple and are allowed to receive incoming connections when this setting is enabled. For example, as iTunes is already signed by Apple, it is automatically allowed to receive incoming connections through the firewall. The firewall software in Mac OS X Server, IPFirewall (IPFW), is from the FreeBSD organization and is a very powerful and sophisticated tool that offers. Applications that are signed by a valid certificate authority are automatically added to the list of allowed apps, rather than prompting the user to authorise them.
