Since Yosemite, I have an issue. Since it was installed in french, the keyboard layout at login is in AZERTY instead of my preferred layout - QWERTY. After being logged in, the layout is corrected to my preference. I managed to add the icon to change the layout back with the "Show Input menu in login window" in System Preferences, but it does not remind my previous choice and seems to return to AZERTY after each boot. I would like to change the default selected keyboard in the login screen. I would like to know if anybody is aware where the default keyboard to use at login is stored somewhere? Any idea? Thanks!
