Just been scratching my head about this. Then I thought, is it just so they can detect authentic Apple cables and scold you for using an inauthentic one? Because iOS definitely does that. Some kind of challenge/response thing that requires a full Turing machine maybe.
Another thought was something to do with monitoring current or degradation but I cant see why they couldn’t do the same things from either the computer in the power adaptor or the computer in the actual computer.
