water on MacBook

FWIW, I recently had a water spill on my 2020 MacBook Pro that resulted in it having to get a new display, track pad, and logic board replacement. I have an AppleCare+ plan with it and the repair cost me $99 US. Far less than an out-of-warranty repair. The AppleCare+ plan allows for up to two "accidental" incidents. In my case, I had used up one of those. Your experience should be the same. You can elect to take your notebook to your local Apple Store, or if more convenient, arrange to have it shipped it to Apple.

If your MacBook is unresponsive or slow after spilling water on it, you probably need a hardware repair. Unfortunately, Apple doesn't cover liquid damage under the warranty, so you'll need to pay for it yourself.

Wow, I stand corrected and that is indeed good news!
