Amethyst

Tiling window manager for macOS along the lines of xmonad. Amethyst is available for direct download on the releases page or using homebrew cask. Amethyst now is only supported on macOS 10.12+. Amethyst must be given permissions to use the accessibility APIs under the Privacy tab of the Security & Privacy preferences pane. Amethyst uses two modifier combinations. Amethyst allows you to cycle among several different window layouts. Layouts can also be enabled/disabled to control whether they appear in the cycle sequence at all. The default layout gives you one "main pane" on the left, and one other pane on the right. By default, one window is placed in the main pane (extending the full height of the screen), and all remaining windows are placed in the other pane. If either pane has more than one window, that pane will be evenly split into rows, to show them all. You can use the keyboard shortcuts above to control which window(s), and how many, are in the main pane.
