Most Mac window tools stop at halves, thirds, and quarters. I wanted arbitrary N×M grids and a way to put a window on any span of cells from the keyboard only.

Quintile does that. Hold Control+Option, hit G, pick two cells (or use presets for thirds/quarters), and the focused window snaps to that span. You can run something like a 5×2 grid, span columns 1–3, leave a tall pane on the right, all without the mouse.

Also: three grid profiles per display, move within the grid, send to next display. Menu bar app. Accessibility permission only. No auto-tiling window manager, no SIP.

Install:

  brew install --cask stefanopineda/quintile/quintile

It is deliberately not a yabai or AeroSpace replacement. Windows stay normal macOS windows until you chord. Happy to answer questions about the grid model or hotkeys.
