MacBook user explains why he files the sharp metal edges off his Apple laptops — unibody design facilitates a surprisingly deep roundover

A MacBook user, Kent Walters, explains why he files the sharp metal edges off his Apple laptops for comfort, using a metalworking file to round over the corners. Walters believes in customizing his tools and found the sharp edges uncomfortable on his wrists. He provides tips for DIYers looking to modify their MacBook edges, suggesting taping off certain areas and clamping the notebook for accuracy. Walters used a rough file and sandpaper to achieve a rounded edge on the palm rest area, cautioning that this project may not be suitable for those concerned about maximizing resale potential.
