Keyboard language change
The keyboard on my macbook has changed itself to some far eastern alphabet all on its own. I discovered this when I could not log into my account (or any other account) due to the password being rejected. Luckily I got into the guest account (no password) and saw that the keyboard was producing strange characters.
Plugged in a USB keyboard which worked fine and got into my account, but the built in keyboard still giving strange characters. Checked the settings and nothing obviously wrong, but made a few changes anyway, got a 'need to restart; for changes to take effect, did so and keyboard back to normal.
How did it spontaniously change? Was working fine previously and macbook restarted from 'sleep' with a different keyboard setting - what is going on?
