I "build" the Unity project with the settings you can see in the screenshots. Our project is on Unity version 2020.3.13f1. After that I follow the Unity manual instructions on how to upload a Unity Mac project to the App Store connect (Unity Manuel: https://docs.unity3d.com/Manual/HOWTO-PortToAppleMacStore.html ).
The Xcode version we are using is the latest version ( 07/28/21) according to the App Store on my Mac Book.
While following this tutorial, as you can see from the screenshot of the terminal, there were complications with the developer name, but we were able to solve that.
Unfortunately, in the following step from the Manuel we have the problem that the Entitlement Data can not be read (see Termial Screenshot).
We did the following:
First, it was an Entitlement Data, as suggested by the tutorial, which came from an empty Xcode Mac project, which we then modified. Then we tried to make the .plist created by Unity into an Entitlement Data, unfortunately both unsuccessfully.
When we tried to upload the project without the Unity Manuel steps we got the following error (see Drive : screenshot_2021-07-26_at_11.36.01) .
After we were advised by the Apple support ,under ( developer.apple.com ) to create the appropriate profiles and devices again, this error message no longer comes.
But for this we can only (as seen in the screenshot : "Screenshot_2021-07-28_at_10.58.20") select only Build Products or Archieve. When we press Build Products and have selected a location, an app icon opens briefly at the bottom of the bar but closes again directly.
