Notarization (macOS)

Notarization is a step where a developer submits an already code-signed app to Apple for an automated scan for known malware. Apple returns a ticket that macOS checks the first time you open the app, which is why non-App-Store apps can still open smoothly instead of being blocked outright.

Why it matters

Notarization is not a manual review of what the app does, it is an automated malware and signing check, so it confirms a baseline of safety rather than vetting an app's actual behavior or claims.

Is notarization the same as an App Store review?

No, it is a lighter, automated check, distinct from the human review process the App Store uses for its listed apps.

Why isn't Claude Keychain on the Mac App Store?

The App Store's sandbox rules restrict the kind of system access some tools in this category need, so some developers distribute directly instead, still signed and notarized.
