  2. Double-click the DMG file to open it and show the installer window.
  3. Drag Calc-U-59.app to the Applications folder.
  4. Eject the disk image and launch the app from Applications.
  5. On first launch, if macOS blocks the app with a Gatekeeper prompt, right-click the app icon and choose Open to approve it.

After first approval, macOS treats the app like any other notarized application. You can then open it normally with a double-click.
