Hey @huanling820713, Would it be possible for you to run the command as below and let us know if that gives you anything additional? codesign -fs FS --timestamp --force --deep --verbose --options runtime --entitlements ENTITLEMENTS TOOL_NAME Happy coding!

No problem at all! When I first started using the API I didn't care about the response headers and now I watch them extremely carefully. Watching the headers is a good way of detecting when Apple is making changes that they do not announce.

Thanks @Developer Tools Engineer for posting this! This is great and I have not seen it yet!
