Use the Mac layout to check built-in MacBook keys, modifiers, arrows, and browser-visible function keys.

Check built-in laptop keys

Run a full key pass when a MacBook key feels stuck, unresponsive, or inconsistent.

Butterfly and scissor keyboard issues

Dust, wear, and liquid can cause missed presses or repeated inputs. Use the report as a practical inspection note.

What this browser test cannot detect

This page cannot inspect physical switch feel, Touch ID, power behavior, or keys intercepted by macOS.

Help

Can this diagnose butterfly keyboard defects?

It can show browser-visible missed or repeated key events, but it cannot physically diagnose the mechanism.

Can this test Touch ID?

No. Touch ID and power behavior are not exposed as normal browser key events.
