I can tell you as someone who is forced to work professionally on a Mac this is by far the stupidest design choice the company has ever made. It’s a lightning port, could easily be fit into the front of the mouse with a basic alteration to the body. I have a backup mouse for when my mouse dies in the middle of working and I don’t wanna stop and wait 20 mins to charge the damn mouse. I also have a wired dell mouse but it only supports up-down scrolling so I prefer to just have two magic mice.
