If you attempt to install Diploma 6.72 but receive an error that the developer cannot be confirmed and therefore Diploma cannot be installed, follow the below steps to solve this problem.


Right-Click the Installer and Click Open


Click "Open" on the warning Screen




An alternative method to fix this problem is to change the Gatekeeper Settings altogether. Choose "Security & Privacy" in System Preferences and change the "allow apps download from.." button to "anywhere."
