Mac Keyboard Test Guide

How to use the mac keyboard test

Press keys on the Mac-labeled virtual layout. Standard browser codes map to their Apple legends, including Command for Meta and Option for Alt.

Understanding the results

Highlights show which physical key codes reached the page. The modifier panel makes Command, Option, Control and Shift combinations easy to verify.

What this browser tool can measure

macOS or the keyboard firmware may reserve Fn, Touch ID, brightness, Mission Control and media keys. Those keys may act normally without producing a browser event.

Private by design

The interactive work happens locally in this browser. No account is required, and test inputs are not sent away to calculate the result.
