Fix damaged app message on macOS sierra or later

you might have to completely disable Gatekeeper checks, and to do that open your terminal and type:

sudo spctl --master-disable

Enter your password and you’re done. Note that there are two (2) dashes before master. You might miss that while copy/pasting.

To verify that your operation was successful you need to open System Preferences and verify that the Anywhere option is now visible. system preferences > security & privacy

Revert the Gatekeeper Settings

To enable Gatekeeper again, enter the following command (notice two dashes before master).

sudo spctl --master-enable
