What is Gatekeeper?
Gatekeeper is a security feature in Mac OS Mojave that prevents the installation of third-party applications that are not from trusted sources. This security measure is designed to protect your Mac from malware and other malicious software. By default, Gatekeeper only allows applications that are downloaded from the Mac App Store to be installed. However, you can change the settings to allow apps from other trusted sources to be installed as well.
How to Change the Gatekeeper Settings

Then, click on the Lock icon in the bottom left corner to unlock the preferences. Next, select the Anywhere option from the Allow apps downloaded from: drop-down menu. Finally, click on the Lock icon again to save your changes.

Assuming you have already set up Gatekeeper on your Mac:
If an app that isn’t signed or registered with Apple tries to open, you’ll see a warning.
