im on mac os and trying to bundle my kivy app to create a package, after creating the .app and the .spec file and trying to create the package using the .spec file, i get an error saying ..../_CodeSignatures/CodeResources is not a valid file. basically a signature is missing. not only the signature but the folder the signature should have been contained in too. im assuming in the first place when creating the .app and the .spec file the signing was never done. im using python3.12

Remember to:

Ask your Python question, not if you can ask or if there's an expert who can help.
Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

did you use this option --osx-bundle-identifier during the build?

#

it seems its a combination of things but security find-identity -p codesigning -v is how you check your identiy for code signing is valid. otherwise your using adhock signing
