By default, Mac OS 10.8.x , 10.9.x , 10.10.x , 10.11.x and macOS only allows users to install or run applications from 'verified sources'. Sometimes, when a known developer (such as Microsoft or PowerSchool) needs to update their application's code to cofirm their 'identity' with Apple, an error may occur. As a result, users may be unable to install or run some applications downloaded from the internet or stored on physical media, and the error below is displayed:
