Why is it that some people can walk into their local Apple Store with a broken MacBook and walk away with a free replacement, and other people are turned away, with Apple claiming the repair is due to user error… even if it isn’t?
It has less to do with whether or not you actually voided your warranty than if Apple thinks they can prove you voided your warranty. And the most important tool Apple uses to prove you’re responsible for the damage to your own machine? It’s a tool that inspects dents.
