It's probably a matter of getting used to the new keyboard. You can't expect to switch to another keyboard and instantly type error free. After using a butterfly keyboard for a while, I struggle a lot with the macbook 2015 one. The keys feel super high and I feel like I have to press the keys super hard to register.
Im two years in and I hate the keyboard. I actually didn’t hate it to start with because the bigger keys felt nice and I figured my accuracy would return after I got used to it, but it’s been literally years and I still make constant typos on this thing. I recently started using an external old-Mac-style keyboard and suddenly I can type without mistakes again, it’s honestly bizarre. Muscle memory wouldn’t last this long, there’s something about the newer design that just doesn’t work for me
Yeah I love the keyboard and now I find others (including mechanical) to feel super mushy and unresponsive. I suspect I'm in a very small minority though.
