A developer has shared their practice of filing down the sharp aluminum edges of their MacBook, particularly around the notch area where the corner is most pronounced. The modification was done to address discomfort on the wrists during extended typing sessions, as the industrial design's precise geometry, while aesthetically pleasing, can be ergonomically challenging.

Using basic tools including a rough file and progressively finer sandpaper (150 then 400 grit), the modification took place in careful increments to avoid damaging internal components. The work was done on a clamped MacBook with taped-off speakers and keyboard to prevent aluminum dust from entering sensitive areas. The result, months later, shows a comfortable blend between the modified corner and the existing notch curve.

This hands-on approach to customizing work tools reflects a broader philosophy of adapting equipment to individual needs rather than accepting manufacturer defaults. The author offers to help others considering similar modifications, encouraging a practical attitude toward personalizing expensive hardware. The technique demonstrates how simple tools and careful execution can transform a device's ergonomics without compromising its functionality.
