OpenMacScreenShade

什麼是 OpenMacScreenShade？

OpenMacShade is a tiny macOS menu bar app that makes your screen appear darker using only a click-through black overlay. Unlike feature-heavy display tools, it does not use hardware brightness control, DDC/CI, gamma changes, private APIs, permissions, telemetry, or network access. It is open source and intentionally simple: one slider, one overlay, nothing else.
