grayscale (updated for macOS 15.1)

An app that makes your Mac grayscale/color via accessibility with one click

Compatible with macOS 10.14 Mojave through macOS 15.x Sequoia

Features

• Silent toggle: When Python 3 is available, the app toggles grayscale silently in the background without opening System Settings
• Universal compatibility: Falls back to GUI automation for systems without Python 3
• One-click operation: Simply run the app to toggle between grayscale and color

Best Usage

• Great for use with Apple Shortcuts or Alfred 5.5 as a Hotkey workflow

Setup

1. Go to System Settings > Accessibility > Display > Color Filters and make sure the filter type is set to Grayscale
2. For the best experience (silent operation), ensure Python 3 is installed:
   • It comes pre-installed with Xcode Command Line Tools (xcode-select --install)
   • Or install via python.org or Homebrew (brew install python3)

Requirements

• macOS 10.14 Mojave or later
• For GUI fallback mode: Accessibility permissions for the app in System Settings > Privacy & Security > Accessibility
