If you use something long enough, you'll get used to its idiosyncrasies. Jobs would have clicked and dragged 10px away from the rounded corner here instinctively. This is why the owner of an old car can turn it on and drive away in a blink while his son has trouble: hold the accelerator 10% down, giggle the key a little while turning, pull the wheel a bit, ... all comes natural to the owner.
Yes, and Mac owners will do the same thing. I don't use MacOS but people will just figure out the new behavior, be briefly annoyed by it, and then get used to it and move on. Apple could have done better here but users acclimate to much worse UX than this.
