How to isolate the damaged keyboard?
Unfortunately my MacBook’s built-in keyboard has been damaged and some keys are malfunctioning. I can’t replace it soon so I should continue to use the Mac until I done my works.
If I use a USB Keyboard to work with my Mac, during boot or in macOS, damaged built-in keyboard will be isolated and won’t damage my MacBook or macOS?
Damage was not by water, I was replaced it before but it seems was not genuine.
