Keyboard selection not sticking
I just got a new MacBook Air today - MacBook Air (13-inch, M3, 2024). I've connected a Magic Keyboard with Touch ID and Numeric Keypad to use with an external display! When none of the keyboard shortcuts were working, I noticed that the selection of the external magic keyboard doesn't seem to stick after I select it. When I X-out of this menu and go back, it automatically reverts to selecting the internal Macbook Air keyboard and I'm guessing that's why the shortcut keys aren't working either. How can I fix this?
MacBook Air 13″, macOS 15.1
