Another thing you should do right away is turn off your MacBook and leave it turned off for at least 48 hours. If your MacBook does not shut down when you hold down the power button, your keyboard may be broken and unable to send the “Force Shutdown” signal to the logic board on a software level. In this situation, you’ll need to use a different way to shut down the laptop. Soak any remaining water on the keyboard surface, touchpad, and screen using tissues or a paper towel.
