- Windows: SmartScreen may warn. Choose "More info", then "Run anyway".
- macOS: the apps are ad-hoc signed, not notarized, so macOS blocks the first launch. Open System Settings > Privacy & Security and choose Open Anyway. On macOS 14 and earlier, right-clicking the app and choosing Open also works.
