MacBook test - complete diagnostic check
Check a MacBook before buying or selling, including keyboard, trackpad, hinges and battery health.
Which device are you checking?
Pick the device in front of you. The checks are tailored to it — a desktop is never marked down for having no battery.
Device details
Everything here is optional. It appears on the report so a buyer knows which device was tested.

The butterfly keyboard years
MacBooks from 2016 to 2019 used a butterfly mechanism with a well-documented failure mode: keys that stick, repeat or stop responding, often after a single crumb. If you are looking at one of those, the keyboard test is the most important thing on this page. Press every key several times, not once.
Battery cycle count
No browser can read it. On macOS it is in System Information under Power. Enter it alongside the health percentage — both are recorded as figures you supplied, because that is what they are.
Trackpad, Force Click and Touch Bar
A browser sees a trackpad and a mouse identically; there is no field that separates them. So the trackpad check confirms which device you actually used rather than pretending to detect it. Force Click and the Touch Bar are guided checks for the same reason.
Screen coating
Some MacBook displays develop anti-reflective coating wear that looks like smudging and does not wipe off. The white and grey full-screen fields show it clearly, and it is worth looking for — it is cosmetic, it is permanent, and it affects the price.

Quick answer
Open it on the MacBook. On 2016-2019 models the keyboard test matters most - press every key several times, not once. Cycle count is in System Information under Power and must be entered manually.
