I am using a PC keyboard and have to switch the Win (⌘ Cmd key) and the Alt (Opt key) for this to feel like a proper Apple keyboard. I have this remapped via System Preferences for my user account just fine.

However, this remapping does not work on the login screen, everything seems to be reverted to as if I haven't done any remapping on the login screen.

As I want to use the Cmd+Shift+Letter to select my face to login without having to touch the mouse it became annoying every time I had to re-remember that the remap only takes effect after I login.

Any suggestion on how can I change the modifier key settings for when I am not yet logged-in?

sudo cp ~/Library/Preferences/ByHost/.GlobalPreferences.*.plist \

and restart.

  • Should this work also for updating modifier keys?
