Start with these three steps
Disconnect external power
Shut the MacBook down and disconnect its charger and accessories. Do not reconnect them just to see whether the laptop responds.
Record the spill
Note the liquid, approximate amount, entry point, time and any charging or restart attempts. Photograph visible damage without opening the case.
Check copies elsewhere
Use a different device to inspect cloud files and existing backups. Make a short list of the items still missing.
Treat a port alert and an internal spill differently
Apple’s liquid-alert guidance says to shut down, disconnect power and allow wet connections to dry. It advises against rice, external heat, compressed air and inserting objects into ports. Supported alerts concern particular ports and models; no alert should be read as proof that the whole laptop is dry.
A drink across the keyboard is a different situation from a damp cable end. Our preservation recommendation for a significant internal spill is to leave the MacBook off for assessment. A dry-looking surface does not establish that the original electronics can safely be powered.

Identify the data that is still missing
Check the latest verified backup date from a working computer. Compare it with the work completed after that date: a thesis chapter, current accounts or photographs imported during travel. This creates a focused recovery request without repeatedly starting the damaged MacBook to investigate.
Record whether a file was local, in iCloud Drive or on a separate disk. A successful cloud login answers only the cloud-copy question. Before accepting a general repair, explain which files have no other copy and ask how the proposed work affects the original storage.

Keep original parts available
Recovery planning depends on the exact model. Some older MacBooks have removable storage; newer architectures can depend on the original board and its encryption hardware. Do not assume that moving memory chips or fitting a replacement board will reveal readable documents.
For an Apple silicon or T2 MacBook, encrypted internal storage adds a hardware dependency. Keep the original logic board and storage components together, including parts removed during an earlier repair. Give an assessor the model, repair history and whether the normal login credentials are available.

Ask for a data-focused assessment
Data Recovery Lab NZ is an external provider whose current MacBook service includes liquid-damage cases. Assessment is needed before any conclusion about recoverability. Describe the missing files and request an explanation of proposed work, costs and the handling of original components.
Ask whether the plan aims to obtain a temporary opportunity to copy data and what happens if the laptop becomes accessible. Specify a separate destination for recovered files. Do not treat one successful start after a spill as a reason to return the MacBook to everyday use.

A realistic view of recovery
- Damage to essential storage or security hardware can prevent recovery even when the login password is known.
- Do not open or press on a swollen, hot or visibly damaged battery area; arrange appropriate service advice.
