I'm wondering how to allow non-identified developers' apps since I updated my MacBook Pro to macOS Sierra.

This option seems to have disappeared.

Can someone help?

You can right-click on the unidentified app and choose open.

You can completely disable gatekeeper with the command:

sudo spctl --master-disable

  • Thank you Chris. It works. To the people who will read this, you can also re enable it by typing : sudo spctl --master-enable
