Chosen Solution
I’m currently using a 3rd party backlit Bluetooth keyboard. Only use this Magic Keyboard that came with my 2015 iMac every now and then. Recently got a Mac mini and tried to use it again and experienced the following: It is detected and pairs successfully, but displays symbols and characters instead of the letters on my keyboard when typing. Tried contacting Apple Support and was advised to do: [1] Factory Reset (Shift-Option-Clicking Bluetooth icon in Menu bar) as shown in the pictures. Removed and re-paired the keyboard but to no avail. [2] Support officer also talked me through a Resetting NVRAM and [3] Deleting keyboard .plist files in xx > Library > Preferences folder. Nothing worked so far. Input sources in Keyboard pane of System Preferences is ABC / U.S International. Is there any way to re-flash the firmware or fix this keyboard still or is it a goner
You’ll need to add in the correct Input source! You have the wrong keyboard type listed! Here’s the correct one:
Use the controls at the bottom
