About Amethyst
Amethyst is an open-source automatic tiling window manager for macOS, designed to function similarly to the xmonad window manager. It automatically arranges open windows into tiled layouts across desktop Spaces. To use Amethyst, users must grant it accessibility API permissions via macOS Privacy & Security settings, and disable the default 'Automatically rearrange Spaces based on most recent use' setting for predictable keyboard navigation between Spaces. The app is only compatible with macOS 10.15 and later.
