Flagjack isn't code-signed, so Microsoft Defender SmartScreen may pop a blue "Windows protected your PC" box. Click More info, then Run anyway. You only need to do this once.
macOS can't verify an unsigned app. Right-click (or Ctrl-click) Flagjack.app → Open, then Open again in the dialog. You only need to do this once.
