Developer ID and Gatekeeper

Gatekeeper on macOS helps protect users from downloading and installing malicious software by checking for a Developer ID certificate. Make sure to sign any apps, plug-ins, or installer packages that you distribute outside of the Mac App Store to let Gatekeeper know they’re safe to install. And now, you can give users even more confidence in your apps running on macOS Mojave by submitting them to Apple to be notarized.

Developer ID Certificates

If you distribute Mac apps, plug-ins, and installer packages outside of the Mac App Store, you can get a unique Developer ID from Apple to digitally sign your software. The Developer ID certificate lets Gatekeeper verify that you’re a trusted developer. Software signed with a Developer ID can also take advantage of advanced capabilities such as CloudKit and push notifications.

Getting Your Apps Notarized

You can submit your apps to Apple to be notarized before distribution. When users on macOS Mojave first open a notarized app, they’ll see a more streamlined Gatekeeper dialog and have confidence that the app is not known malware. Notarized apps are signed with a Developer ID certificate and include a ticket from Apple.
