The long way to open an unidentified, downloaded app in Sierra
- Go to Apple menu > System Preferences, and then click on the Security & Privacy icon.
- Under the General tab, look in the setting for “Allow apps downloaded from” and you should see that the app you tried to open was noticed by the operating system. Click the Open Anyway button to open that new app.
Sierra will then note the developer and add it to its internal list of identified developers. If you download a different app from the same developer, Sierra will look for the developer on the list and if it sees the developer, the new app will open.
