Frequently Asked Questions

How do I test my MacBook keyboard?
Open this page in Safari or Chrome, click anywhere on the keyboard diagram, then press each key. Keys light up green when registered — making it easy to identify any non-functional keys.
Does the MacBook keyboard tester work without downloading anything?
Yes. KeyTest runs entirely in your browser using standard Web APIs. No app, extension, or plugin is needed.
Can I test the Command and Option keys?
Yes. The MacBook layout includes Command (⌘), Option (⌥), Control, Fn, and the full Function row (F1–F12 / media keys), all of which are testable.
Is my webcam or microphone data stored?
No. Webcam and microphone access is processed locally in your browser only. No audio or video is recorded, transmitted, or stored anywhere.
Why is a MacBook key not responding?
Some browser shortcuts (like ⌘W or ⌘T) are intercepted by the OS before reaching the page. For those keys, check if the key registers in a text field instead. If it does not, the key may need a hardware inspection.
Can I test my MacBook keyboard for free online?
Yes. KeyTest is completely free — no account or download required. Open the page in Safari or Chrome and press each key to check.
Does this work with the Magic Keyboard or older MacBook models?
Yes. The layout covers all standard MacBook keyboard configurations. Command, Option, Fn, and media keys are all supported regardless of model year.
