First launch

The current releases are not signed with a paid developer certificate, and the macOS app is not notarized. Check that the file came from GitHub Releases.

If macOS says the developer cannot be verified, open System Settings → Privacy & Security and choose Open Anyway. Apple’s guide explains the different warning types.

In Windows SmartScreen, you can choose More info → Run anyway. Organization policies or other restrictions may make this option unavailable.

Connecting a film scanner needs the separate scanner plugin.
