Seeing a security prompt on first launch? Here's what to do
Windows: Windows may show a SmartScreen notice on first run. Click "More info" → "Run anyway" — Lightning Assist is a verified, code-signed publisher (Lightning Assist S.R.L.).
macOS: macOS may quarantine the first launch. Right-click the app and choose "Open" once to confirm — the DMG is notarized by Apple.
