Hi, I have an app generated by using osacompile on an applescript file. The app works fine as expected. However, when I try to sign it, I get two errors as in the screen shot below: After some googling around, I deleted the _CodeSignature folder in the .app directory but still signing fails with the same error. So, I would like to know two things: Is it possible to sign .app files created using osacompile as in my case? If yes, what am I missing and how to resolve my situation. Thanks,
