Inizia riproducendo il malfunzionamento con la sequenza documentata q login e q su macOS, quindi confronta l’output di q doctor prima e dopo q restart. Traccia lo stato di accesso utilizzato dal CLI e dalla GUI; il lavoro è completato quando un accesso riuscito viene riconosciuto dai comandi q senza richieste di accesso ripetute.
