The app won't open or quits on launch

macOS

On Apple Silicon Macs, make sure Node Composer was moved into the Applications folder before launching — running it from the disk image can prevent it from starting. If the issue continues, try:

• Right-click the app → Open, then confirm.
• Send us the crash log shown by macOS, we’ll diagnose it.

Windows

Write to info@node-composer.studio with the error Windows shows on launch, and we’ll diagnose it.
