Ferrocast Install

40 window commands, in the launcher you already use

Ferrocast has 40 commands that move and resize the frontmost window: halves, thirds, fourths, quarters, sixths, maximize, center, nudge, and moving to another display. Run one by typing its name in the launcher, or give it a hotkey with ⇧⌘, on the command. It is free and open source (MIT).

You may not need another app at all: macOS has built-in tiling with the green button, the Window menu and Fn-Control-arrow shortcuts (Apple). And Rectangle is a dedicated window manager that is free to download, with a paid Pro version. Ferrocast is for people who would rather have it in the launcher.

  3. Run a command. Open the launcher with ⌥ Space and type, for example, “left half” or “next display”.
