Invalid Signature for submitted Mac App

[tonyd]

After a successful submission to the Mac App Store, I got an email from Apple saying this:

Dear Developer,

We have discovered one or more issues with your recent binary submission for XXX. Your app has proceeded to review, but the following issues should be corrected in your next submission:

Invalid Signature - the executable XXX.app/Contents/Frameworks/MonoEmbedRuntime/osx/libmono.0.dylib is not signed, the signature is invalid, or it is not signed with an Apple submission certificate.

I know others have received the same message, what is the solution?

Because I’m pretty sure the signature is valid and signed by Apple.

Anyone know the solution to this?

Or is it something that needs to be fixed by Unity?

codesign -f -s “3rd Party Mac Developer Application: name” /path to /Contents/Frameworks/MonoEmbedRuntime/osx/libmono.0.dylib
