- How To Allow Apps From Other Developers On Mac Computer
- How To Install Downloaded Apps From Outside The Mac App Store
Jan 26, 2017 In the previous version of Mac OS X, when you want to install an app that downloaded not from App Store, you can simply go to Security setting General tab and tick “ Allow apps downloaded from: Anywhere“. If the other users can see the applications, and open them in trial mode, there's nothing wrong with where the application is stored on disk. It also doesn't matter whether the other users are admins or not. The problem is that the apps store their registration info per-user. It's possible the apps have an option to store the info globally.
Background:
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:

Open the System Preferences. This can be done by either clicking on the System Preferences icon in the Dock or by going to Apple Menu > System Preferences.
