Unable to remove /reconfigure external keyboard configuration in System Preferences
Solution 1:
I found ignasi35's suggestion works as an answer to this question of how to reconfigure an external keyboard, that is:
- Unplug external keyboard
- Delete
/Library/Preferences/com.apple.keyboardtype.plist - Reboot
- Plug in external keyboard
In my specific situation my ` and § keys were swapped and reconfiguring did put them back.
