You can also allow only a certain app by following guide at: https://stackengineer.com/macos/allow-apps-anywhere.html This would stop the need from disabling gatekeeper in general.

As of April 23, 2017.... None of these options work.

Go here to get the 'anywhere' option - took me 2 minutes to fix: 1. Open the Terminal app from the /Applications/Utilities/ folder and then enter the following command syntax: sudo spctl --master-disable 2. Hit return and authenticate with an admin password 3. Relaunch System Preferences and go to “Security & Privacy” and the “General” tab You will now see the “Anywhere” option under ‘Allow apps downloaded from:’ Gatekeeper options

This didn't bring back the option. Should it still work?

Rob Chesworth - February 13, 2017 at 11:16pm

the command is actually: sudo spctl --master-disable I guess it must have changed in an update.
