I’ve updated the OS to Sierra 10.12.4 on my Macbook Pro Retina after which Magic Mouse started going crazy with the scrolling speed significantly increased (even with the minimum scrolling speed set in mouse settings), while both the mouse and the trackpad won’t scroll.
Luckily, I was able to revert back to 10.12.3 via Time Machine and everything seems to be working on this version…
What should I do to solve this problem and why does it happen?
