I’m considering a used M1 MacBook Air and want to check for Activation Lock before I pay. If I’m meeting the seller in person, what should I ask them to show me on the Mac?

Is seeing the “Hello” screen enough, or should we connect the Mac to Wi‑Fi and go through setup together to see whether it asks for the previous owner’s Apple Account?

If you’ve bought a used MacBook in person, what did you check before handing over the money? Which screen gave you confidence that you could set it up with your own account?
