Ignore built-in keyboard if external keyboard is connected
The built-in keyboard on my MacBook Pro is defective and it sends a signal that the power button is constantly being pressed. So when you turn on the MacBook, it will shut down again immediately. If you press "cmd", the on / off signal cannot be sent. That way I can use the MacBook, but it's no fun ... If I could ignore the built-in keyboard and work with an external keyboard, that problem would be solved. In Settings, you can ignore the trackpad when a mouse is connected to the Mac, but I couldn't find the same thing for the keyboard.
Can someone help?
MacBook Pro 13″, macOS 10.15
