- The app will list all drives in your system. Pick the one you would like use as macOS USB installer.
- Ignore the warning message and proceed to Erase and Create macOS USB disk. Don’t forget to provide your admin password when it prompts.
- Keep checking notifications tab for progress. When it completes you will find Install macOS Mojave (or High Sierra) mounted to your desktop as a USB disk.
- That’s your backup. Unmount and keep the USB installer to a safe place.
