Gatekeeper is a security feature that Macs use to protect themselves from dangerous apps and publishers. If you try to install an app from a third-party developer that is not available on the App Store, Gatekeeper will be unable to confirm that the app is malware-free.
There are risks associated with installing software from unverified publishers, but if you are aware of these risks and you trust the publisher, feel free to do so. Install the software if it was made specifically for your Mac by your company administrators, which is typical in the corporate sector.

Enable Apps from “Anywhere.”
Step 2: macOS 10.13 has a new feature called “Anywhere” in System Preferences > Security & Privacy. This allows users to install apps from anywhere instead of just App Store or identified developers. If you have the “Anywhere” preference enabled, any app installed on your Mac can be used, regardless of where it was installed before.
The good news is that you can bring it back using a simple terminal command. Open the Terminal and enter sudo spctl –master-disable. ..
Step 3: Now, enable the “Anywhere” option in System Preferences > Security & Privacy. You can now install and run apps from anywhere you want to.
If you want to revert to the default settings, use the command sudo spctl –master-disable. This will disable the option.
Final Words
If you’ve ever tried to open a programme from an unknown developer, a security warning would have appeared warning you that the programme “cannot be opened because the creator cannot be verified.” The first notification is followed by another saying “macOS cannot verify that this app is free of viruses.” ..
