What is your Docker Desktop verison and macOS verison?
The executable should be here on Mac:
/usr/local/bin/docker-credential-desktop
You can check the folder if ther eis anything Docker Related or even this file with wrong permissions (not executable)
You can share the output of this command:
ls -la /usr/local/bin/ | grep docker
Maybe you need to reinstall Docker Desktop if something happened during the installation.
PS:: It would be much better if you could share texts in code blocks instead of screenshots of texts. Here is our formatting guide: How to format your forum posts
