Because this application is not signed with a paid Apple developer account, you will need to manually grant it the necessary permissions after installation.
Apple's Gatekeeper technology is designed to ensure that only trusted software runs on your Mac. Since this app is from an unidentified developer, you will need to take a couple of extra steps to run it.
After downloading and moving the application to your Applications folder, open the Terminal application and execute the following three commands:
Navigate to the Applications directory:
bash
cd /Applications
Grant execute permissions to the application. The sudo chmod -R 777 mcduhub.app command changes the file permissions to allow all users to read, write, and execute the application. The -R flag ensures this permission is applied to all files within the application bundle.
bash
sudo chmod -R 777 mcduhub.app
Remove the application from quarantine. The sudo xattr -cr mcduhub.app command removes extended attributes, including the com.apple.quarantine flag that identifies the app as having been downloaded from the internet. This step is necessary to bypass the macOS warning for unidentified developers.
bash
sudo xattr -cr mcduhub.app
