回答“Why the power connector is overheating?”I have this problem too. When I got this problem I searched about this and saw many users had this issue. Seems like Apple doesn't care about their faulty charger. I doubt that do they really have a proper engineering team to fix this issue . I felt bad now being a mac user first time by seeing this issue persisting for a very long period of time. Extending warranty doesn't make sense if you get the same designed charger again, because anyways its going to get the same issue in few days.
