This device is fully functional, however I reset it and removed my iCloud since i upgraded to the MacBook M5 Max. However once I tried to setup again it showed me the -2003F error, also once I unplugged it, it died ( may be due to using regular type c charger n brick ) great laptop for someone who can get into it. iCloud is removed, laptop only no box or charger since I sold those separately. Thanks for viewing
