MacBook Pro 13" Retina Display Late 2012 Teardown - iFixit

An interesting part of the teardown.

At first we thought we found some kitten fuzz, but it turns out that Apple glued in a small piece of steel-wool-like metal on top of two of the speaker screws.

Why, you ask?
We don't know, but we have some hypotheses:
Grounding?, Noise reduction?, Tamper-evident seals?

When i saw that, I was curious what steel wool can do inside. what if that comes loose and it touches the logic board? What if it comes loose and touches the battery connectors and shorts it out so it expands and explodes?

Apple made a great machine, but a bad choice. want tamper evident seals, use a sticker that said VOID when removed on the areas necessary
