Hi @ChuckMN, I would like to avoid going down the manual signing route if possible. We had hoped that using the API Key would allow us to stop messing about with authentication session hacks. We are using Fastlane as well, but in troubleshooting this I took the approach of just using Apple's tools directly to remove any variables.

Unless the reset was done via a MDM system that would have logs for it, the most obvious way to tell is that the device is in a factory reset state.

Based on feedback from DTS: You can't use an API Key with xcodebuild when exporting a Developer ID Mac app. The recommended path for us was to go back to manual code signing. You can use fastlane with the API Token you can download the profile that you need and export using manual code signing. You can use curl with the API Token you can download the profile that you need and export using manual code signing. You can sign an account into Xcode you can use xcodebuild and export using automatic code signing. You can't use an API Key with xcodebuild when exporting a Developer ID Mac app. I filed: FB9963401
