Technical Overview

Padrail is a free macOS utility that turns your MacBook trackpad edges into physical sliders. It allows you to adjust system volume, display brightness, and keyboard backlight by sliding along the trackpad margins. The top edge dynamically adapts to the active application, providing contextual control. Built for efficiency, it works on both Apple Silicon and Intel Macs without affecting standard trackpad gestures.
