Grayscale Mode

Grayscale Mode is a macOS utility that adds a menu‑bar control for the system‑wide grayscale filter. Users can enable or disable the filter with a single click in the status bar, or by pressing a configurable global shortcut (default ⌥⌘G). The app also allows exclusion of specific applications, so grayscale can be turned off automatically when those apps are active.

The software is open source and released under the MIT license, with the code hosted on GitHub. It relies on lightweight macOS frameworks for launch‑at‑login support, modern user‑defaults handling, and global shortcut management. The repository includes screenshots and a download link for the latest stable release.

Grayscale Mode targets macOS users who want quick, keyboard‑driven access to the grayscale display setting without navigating System Preferences, and who may need per‑app exceptions. It is provided free of charge and is considered stable for everyday use.
