how to disable internal keyboard of MacBook Pro
I want to disable my internal keyboard of my Macbook (Mid 2014). Is there any way for it?
The reason of this: The button <ALT> seen always pushed; so, I can not use normal keyboard. The solution that offered is new keyboard but it is too expensive for now! I want to use external keyboard and it partially works but because of <ALT> problem, all problems going on except writing anything like this message.
MacBook Pro 13″, macOS 10.15
