App code sign verification fails on OS X after 10.11.4 update

    Sorry for the late reply. It seems Apple has changed how the signature is verified and it may be failing depending on the platform in which the installer is signed. We have checked that the InstallBuilder built-in method for code signing still works properly. Could you check if it works for you? You can find more information about this method in this link to the documentation.

    I'm having the same issue here, I have generated a dmg using the built in code signer and get the same error about the App being damaged. Any progress on this?

    Hi George,

    Are you using the latest IB version? Does this error occur every time you try to build the project?

    Best regards,
