TapNoiseA liquid spill is a hardware incident, not a reason to start Clean Mode. An input hold only changes event handling; it cannot isolate power, remove moisture or establish that the Mac is safe to use.
Stop the software test
Do not keep typing or playing sounds to see whether every key still works. Disconnect external power and accessories when safe, turn the Mac off and seek the appropriate service guidance.
If a power adapter, outlet or cable is wet or damaged, avoid handling an unsafe electrical setup. The immediate priority is safe disconnection and qualified advice, not preserving a typing streak or finishing a recording.
Avoid improvised certainty
A dry-looking surface does not prove the inside is dry. A short wait, a working screen or normal audio playback does not rule out damage.
Do not use heat, force liquid through openings or follow an arbitrary restart timetable from an unrelated device. Contact Apple or a qualified service provider for the specific situation and model.
Resume ordinary care later
Apple’s cleaning guidance keeps liquids away from openings and recommends service help if liquid gets inside. Follow that process before treating the Mac as ready for regular use.
Once the hardware is known to be safe, the keyboard cleaning guide covers routine maintenance. Clean Mode remains an input convenience, not a spill-protection or repair feature.
