Filing the corners off my MacBooks

Comfort and Sharp-Edge Problem

• Many report the front edge and especially the trackpad notch corners as literally painful, causing marks, calluses, even small cuts over time.
• Others say they never notice the issue or even enjoy the sharpness as a fidget/sensory stimulus.
• Some note the problem is worse on older Intel unibody models; M‑series machines are perceived by a few as slightly less sharp.

Form vs Function in Apple Hardware

• Recurrent complaint: Apple prioritizes clean seams and “crisp” aesthetics over comfort and ergonomics.
• Examples raised: sharp MacBook edges, glossy screens, hard‑stopping keyboards, port removal, sharp Apple Watch Ultra edge, harsh Apple TV remote.
• A minority strongly defend the hardware as overall best‑in‑class (battery, trackpad, audio), seeing edges as non‑issue.

DIY Modifications and Techniques

• Many admit to filing or sanding edges on MacBooks (and other laptops, drawer handles, etc.), often just at the notch corners.
• Suggested methods: fine single‑cut files, progressively finer sandpaper/Micro‑Mesh, careful long strokes to keep a consistent chamfer.
• Concerns: aesthetics (uneven, “tacky”), loss of anodization causing two‑tone look, possible reduced structural strength, and screen seal or coating wear if the lid no longer meets uniformly.

Ergonomics and Posture Debate

• One camp: if your wrists touch that edge, your posture is harmful; edges wouldn’t matter with “proper” height and arm angle.
• Counterpoint: laptops are used in varied, often non‑desk contexts; blaming posture is seen as “you’re holding it wrong” deflection from a real design flaw.

Work-Device Ownership and Resale

• Some view modifying employer‑owned machines as questionable due to contracts, resale, or leasing obligations.
• Others argue comfort and productivity outweigh resale concerns; depreciation is trivial compared with salary costs.

Electrical Tingling and Corrosion Issues

• Multiple reports of a “buzz” or tingling when touching metal cases while charging, particularly with 2‑prong adapters or poorly grounded outlets.
• Several users link pitting and razor‑like edges to acidic sweat and the breakdown of anodized aluminum, sometimes exacerbated by stray currents.
• Using grounded extension cables or different charger heads is said to reduce tingling, though technical details are debated.

Alternatives: Cases, Peripherals, and Other Hardware

• Many solve edge discomfort with snap‑on plastic or leather cases, neoprene sleeves, or wristbands/braces.
• Others avoid the issue by docking: external monitor, keyboard, and pointing device.
• Some argue ThinkPads and other laptops manage comfortable edges better, but others insist nothing else matches MacBook efficiency and integration.

Attitudes Toward Customizing Tools

• Strong approval from many for the core message: it’s legitimate to modify tools, even expensive ones, to fit your body and workflow.
• Others are viscerally horrified by filing a MacBook, seeing it as vandalism of a “finished” object or poor craftsmanship that should be CNC‑done if at all.
• Several liken wear, filing, and patina to beloved, well‑used industrial tools or instruments.

Offshoot Debates: Corners in UI and Screen Shapes

• A subthread argues physical objects should be rounded while on‑screen windows should remain square/right‑angled.
• Discussion branches into square vs wide monitors, square phone screens, older UIs with sharp window corners, and preferences for pixel efficiency vs aesthetics.
• Some envision future VR/AR interfaces with fuzzy or non‑rectangular “fields” instead of windows.

Seasons Side Discussion

• Another subthread reacts to a different post by the same blogger about when seasons “should” start.
• Participants compare astronomical vs meteorological definitions and region‑specific traditions (Europe, Australia, Ireland, Nordic countries, India).
• Consensus: seasonal boundaries are somewhat arbitrary and climate‑dependent; different cultures and latitudes naturally adopt different schemes.
