Fix the macOS “app is damaged” warning
macOS attaches a quarantine flag to apps downloaded with a browser, which triggers the “damaged and can’t be opened” message. The installer is not actually damaged — clearing the flag fixes it.
The fix
- Make sure Clash Verge has been dragged into the Applications folder.
- Open Terminal (search for it in Launchpad).
- Run: sudo xattr -r -d com.apple.quarantine "/Applications/Clash Verge.app"
- Type your login password (no characters are shown while typing), press Enter, and open the app again.
Why this happens
The macOS Gatekeeper shows this warning for internet-downloaded apps that have not gone through the notarization process. Clash Verge is open source — you can audit the entire codebase in the GitHub repository; removing the quarantine flag simply tells the system you trust the app.
