First launch on Windows
- Run the .exe installer.
- SmartScreen may say "Windows protected your PC" — click More info → Run anyway. The build is unsigned for now, not malicious.
- Finish the installer as usual.
First launch on macOS
- Open the .dmg and drag the app into Applications.
- Right-click it in Applications and choose Open — a plain double-click will be blocked the first time.
- Confirm Open. Every later launch is normal.
If macOS calls the app "damaged", clear the quarantine flag in Terminal and retry step 2:
xattr -cr /Applications/JingleLayer.app
Both warnings go away once code-signing certificates are in place — Apple Developer ID and Windows EV are on the list.
