The macOS and Windows preview packages are unsigned. The macOS app is internally sealed and verified, but not Apple-notarized: Control-click Mapper, choose Open, then confirm Open. If macOS still blocks it, use System Settings > Privacy & Security > Open Anyway. In Microsoft Defender SmartScreen, select More info, then Run anyway.
The Android APK is preview-signed for direct installation rather than Play Store distribution. Uninstall an older preview first if Android reports a signing conflict.
