He revisado la pregunta de Askdifferent aquí: " Este ID de Apple es válido pero no es una cuenta de iCloud ": odio abrir una nueva pregunta sobre este tema, pero ninguna de las respuestas o sugerencias han funcionado para mí.
Puedo iniciar sesión en iCloud.com utilizando la ID y puedo acceder al correo, etc. sin problemas. He intentado iniciar sesión en iCloud en Preferencias del sistema y aparece el error en el título. He intentado agregar el ID de iCloud al usuario en "Usuarios y grupos" y también sin el ID de iCloud allí y obtengo el mismo error. He reiniciado varias veces. He aplicado todas las actualizaciones de seguridad disponibles al sistema.
Me he quedado sin cosas para probar ... La información del sistema se muestra a continuación.
