Disable Gatekeeper from the command line – macOS

by

Launch Terminal if you haven’t done so yet (/Applications/Utilities/) and issue the following command to turn off Gatekeeper:

sudo spctl --master-disable


Hit return and enter the admin password as usually required by sudo, and Gatekeeper will instantly be disabled. If you feel like confirming this, you can do so with the –status flag and the same command, like so:

spctl --status

This will report back ‘assessments disabled’ to indicate that Gatekeeper has been turned off. You will also find that the Gatekeeper Security preference panel will be set to ‘Everywhere’.
