Gatekeeper is a security feature built into Mac OS X, which helps prevent unauthorized applications and code from running on a Mac. Most users have encountered Gatekeeper before when they go to open an application downloaded from the internet where you will see an error message ‘App cannot open because it is from unknown developer’. Since Gatekeeper is a valuable security feature, almost all Mac users should leave it enabled, but some advanced OS X users, developers, and system administrators may need to disable Gatekeeper. While you can do that, users will notice that Gatekeeper turns itself back on after a period of 30 days has passed, which basically means that Gatekeeper will turn itself back on, even if it’s turned off.

This is a certainty feature called ‘Auto Rearm’ and it’s a new addition to Gatekeeper in macOS Sierra, OS X El Capitan and Yosemite, but with a little effort it can turn on automatically feature can also be turned off.

Disable Gatekeeper Auto-Rearm Feature in Mac OS X

With a standard command string, you can prevent Gatekeeper from reactivating itself after it has been disabled for 30 days. This is true for modern versions of Mac OS X, but is really only relevant for advanced users.

Open the Terminal application (/ Applications / Utilities) and enter the following default command string:

sudo defaults write /Library/Preferences/com.apple.security GKAutoRearm -bool NO

Hit return and enter the admin password as usual, this will prevent Gatekeeper from turning itself back on after 30 days the next time you use the feature off in the settings or from the command line.

Re-enable Gatekeeper AutoRearm with default settings in Mac OS X

To go back to the default setting and return Gatekeeper to its automatic reactivation capabilities after 30 days, simply enter the following command string into the terminal:

sudo defaults write /Library/Preferences/com.apple.security GKAutoRearm -bool YES

Hit return again and enter an administrator password, Gatekeeper will turn itself back on as intended.

Should the average user do this? No. Even for advanced users, this can be considered slightly extreme, and perhaps a better approach is to manually add Gatekeeper exceptions for apps if needed, or just use the bypass method via System Preferences when an app is found by Gatekeeper.
