So obviously, every MacBook before 2020 has a butterfly keyboard but now that they support magic keyboards again, can they replace my entire keyboard with a magic keyboard if I pay them to?
Sorry the mechanics of the butterfly keys is very different from the older (magic) scissor keys Apple is now using again. There is no way to effectively convert the 2019 and older system to the Magic Keyboard keys. If you really want the better keyboard then you’ll need to buy a 2020 16” or 13” system.
