Power the MacBook off immediately (hold the power button ~10 seconds — don't shut down normally), unplug the charger and everything else, and turn it upside-down in an open "tent" shape so liquid drains away from the board. Do not turn it on, charge it, press keys, or use rice. Then get it to a repair specialist as fast as you can — corrosion starts within hours, and speed is what saves the machine.
The spill itself rarely kills a MacBook instantly. The real damage is corrosion — liquid reacts with the powered circuitry and metal contacts on the logic board, and it keeps spreading long after the surface looks dry. That's why a MacBook can seem fine right after a spill, then fail days later.
Two things drive the outcome: how quickly you cut the power, and how quickly the board gets professionally cleaned before corrosion sets in. Everything below is about buying time.
Work through these immediately, in order:
These common "fixes" make water damage worse, not better:
No — and it's one of the most persistent myths. A MacBook isn't sealed like a phone; the liquid is already inside, in contact with the board. A bag of rice can't draw moisture out of internal components it can't reach, and it does nothing to stop the corrosion that's already begun. Worse, the hours spent "drying in rice" are exactly the hours a technician needs to clean the board before damage becomes permanent — and rice dust and starch can leave their own residue in the ports.
If you want to slow evaporation-related surface moisture while you get to a shop, an open tent position in a dry room is far better than rice.
Not all spills are equal. Plain water is the least aggressive. Sugary and acidic drinks — coffee, tea with sugar, soda, juice — leave sticky, conductive residue that keeps causing shorts and corrosion even after drying. Salt water is the most corrosive of all. If the spill was anything other than clean water, treat it as more urgent, not less, and get it cleaned professionally as soon as possible.
Professional water damage repair is far more than "drying it out." At our Business Bay workshop we open the MacBook, disconnect the battery, and inspect the logic board under magnification for liquid residue and corrosion. The board is cleaned — often ultrasonically — to remove corrosion from the tiny components and contacts, damaged parts are repaired at board level, and the machine is tested thoroughly before it's returned. Full details are on our MacBook water damage repair page.
