On filing the corners off my MacBooks

Show thread420official1d ago

I just did this to my MacBook not because of the sharp edge but because the pitting turns a sharp edge into a sawblade. Something about the grounding on on the frame when plugged in mixed with my sweaty hands leads to damage along this sharp edge on every MacBook I've ever owned.

This comment is concerning.

> acidic sweat. once you got through the anodization the raw aluminum wears faster....

If one files off the sharp edges, won’t the sweat eat through everything faster, as that protective layer was filed off.

Aluminum should oxidize essentially instantly.

Anodizing and oxidation are 2 totally different things.

True; however, this is an aluminium alloy. These typically have lower corrosion resistance and are most commonly anodized because of it. The applied layer is typically 3 to 5x thicker than that formed by pure aluminium oxidization.

Probably. But, the time when the laptop is taped off would be uniquely a good time to hit it with some polyurethane or something clear to protect it from that sort of damage? Just make sure you hit it with compressed air first so you aren't gluing the aluminum dust to the chassis?
