macOS cannot open the app

Check the official source and the system, architecture and signing information in file details. Use the product’s DMG or ZIP and follow its guide to install in Applications.

If the first launch is restricted, read the message and verify the source. If you trust the file, follow Apple’s official instructions for that app in System Settings → Privacy & Security.

Keep system-wide security protection enabled. Stop and contact support if macOS reports damage or malware. Ask the administrator for help on a managed Mac.
