Condition
Is it really new, or just sold as new? Fill in what you can see and Lidcheck tells you whether it is brand new, open box, Apple refurbished, third-party refurbished or second hand.
The verdict is an estimate from the evidence you enter, not proof. An Apple Store or Apple Authorized Service Provider can confirm history from the serial. Lidcheck is independent and not affiliated with Apple.
Checklist
Choose how you are buying. The checks change to fit, from sealed box signs for new to lock and wear checks for second hand.
Test tools
Open this page on the MacBook you are checking. Each tool tests something a seller can’t fake in a photo.
Part number decoder
From System Information or the box label, like MRX33LL/A.
Common region codes
Keyboard
Click the keyboard, then press every key.
Hold fn to test F1 to F12. Press Command on its own, since shortcuts can trigger the browser.
Display
Full screen colors for dead pixels and backlight bleed.
Click or press Space for the next color, Esc to exit. Black shows stuck bright pixels, white shows dead ones.
Speakers
Turn the volume up and listen for buzz or rattle.
The sweep is the best rattle test. Listen closely at the low end.
