Despite clearly easily removable by pulling out all the stretch-release adhesive tabs, Apple mandates the batteries of these models to be replaced with the entire lower case with keyboards and speakers. Apple even allowed the batteries of M1 MacBook Air to be user-serviceable, but not the Pro models. Apart from immediate accusations of corporate greed, what could the technical reasons for them to eventually decide not to allow end users self-service the batteries despite clearly intended to allow such operation by design?
FRU’s! Apple has been beating the drum for quite a few years reducing the number of FRU’s per a given series. They also look at it for their tech skills level. At one point they had folks with the needed chops to even pickup a soldering iron to tag a joint if that is all it took. Now Apple is a replace it and throw it attitude! While we don’t see it the recovery aspect is not their only putting the part into grinder! So a missing resistor on a board is chuck it not fix it! Here a dead battery is chuck the whole upper case and even the keyboard is not replaceable so its again chuck it out too! WASTEFUL SO WASTEFUL!!! But thats green right???
