The checks
In the order to run them: before opening the DMG, then after installing.
Download checksum
The file you downloaded is byte-for-byte the one published on its app page.
Apple notarization
Apple scanned this build for malware and approved it.
Notarization ticket stapled
The approval travels with the download, so it opens on a Mac that is offline.
Developer ID signature
The app is signed by its developer and has not been altered since.
Hardened runtime
macOS blocks code injection and other tampering while the app runs.
Entitlements review
The special permissions built into the app are limited to what it needs.
What these mean
Signature
A Developer ID signature ties the app to the developer who built it and breaks if anyone changes a file afterwards.
Notarization
Apple scans the build for known malware and records its approval. macOS checks that record the first time you open the app.
Checksum
A SHA-256 value identifies a file exactly. If yours matches the one published on the app page, the file was not changed on the way to you.
Hardened runtime
Stops other code from being injected into the running app.
Results for each app
Test results are recorded on each app page when the build is published.
