MAS: Code Signing Identity Private Key

Question

I've removed all development and installer certificates from the development portal, created a new CSR and generated new Application and Installer certificates.

Now I'm about to distribute the App to the MAS and am constantly presented with this error:

"Name" is a valid identity. However, the private key for the associated package
identity "Name" is not installed on this Mac.

Developer Profiles from a different Mac can be imported.

This puzzles me, since the private key is on the System, how else could I've generated the certificates without them?

Answer 1

Double check you have removed all old certs, there is a menu item in the KeyChain app to show all expired certs. I threw away all expired certs and things started working.

Answer 2

Got it working:

• Created a new user account on my Mac
• Cloned the repo there
• Removed all Provisioning Profiles and Certificates from the Dev Portal
• Let Xcode generate all the Certificates for you
• Upload works!
