I have a Beta version of my macOS App that I would like a Test User to be able to test. They already have the released version installed on their machine, so this is a 2nd version. When they start it up though, the "Apple-ID" text box is greyed out and uneditable and contains their "real" Apple ID. They are not able to even enter the Sandbox Test User information.
What needs to be done to trigger the "new" Apple ID to be used?
Just FYI, yes all the other get "Hardware-UUID", new Provisioning Profile, Archive, Export for Development stuff has been done. It has been successfully installed/started by others. But they are previous Beta testers and this person is a new Beta tester. What are the requirements for being able to use a different (Test) Apple ID for the first time?
