Love this! I did this in 2020 and until today I hadn't seen anyone else who had done it. If anyone is tempted, I recommend finishing the job with Micro-Mesh. IIRC, I went up to 12,000 grit and it results in a nicely polished look that catches the light beautifully.[1] I bet it would look even more striking on the actual black MacBooks we have today.

Black macbooks are anodized aluminum which are thin coatings that would be removed when filing. It might look cool but it’d be the silvery color of raw aluminum

[stevenpetryk]

worth noting that silver macbooks are also anodized aluminum, so you'll also be filing off anodization

Yes, exactly. The point I was trying to make is that with a black finish, exposing the original color of the aluminum would be even more striking.
