MacOS publishing, unable to sign app

Hello all,

Trying to publish an App to the macOS App Store, I have an valid and in-date Mac App Distribution, Mac Development certificates installed plus the provisioning profiles for both and they are unique and used in the GameSalad Publish Portfolio. I have deleted and reinstalled all the above. They do exist in X-Code and I've verified that they do.

I get he following error and I'm trying to figure out what I am doing wrong.

    Do you have the certificate installed in your Keychain? Provisioning Profiles in Xcode is just one half of the equation.

    Thanks for the reply.

    Yes I have certificates installed in my Keychain and the Provisioning Profiles installed in Xcode.

    Do you have the correct WWDR cert installed too? Usually see this error when either WWDR cert is missing or duplicate certs exist somehow.

    I'll take a look at WWDR cert, will need to Google that. My iOS apps build and sign without any problems.

    I don't know why they make this stuff so hard.

    Having trouble signing my MacOS app as well. Bit of a mystery how all these things are meant to plug together!

    I struggle every time, and I've been doing it on and off for years.
