Docker Desktop on macOS reported Docker.app is damaged
Docker.app is damaged and can't be opened. You should move it to the Trash.
macOS marked Docker Desktop as damaged after a partial or interrupted copy during DMG-based installation, often because another application was calling the Docker CLI while the app was being installed or updated.

Observed message
Docker.app is damaged and can't be opened. You should move it to the Trash.
Why it happens
The drag-and-drop installation from the DMG was interrupted.
Another application such as an IDE or terminal process was using Docker CLI symlinks during installation.
Docker Desktop was left in a partially copied state and macOS Gatekeeper marked it as damaged.
How to fix it
Quit applications that may call Docker in the background, including IDEs, terminals, and agent tools.
Remove the partial /Applications/Docker.app install and empty the Trash.
Re-mount the DMG and reinstall Docker Desktop cleanly, keeping the installer volume mounted until installation completes.
