Lasso 1.8.2 — Mac version

Lasso is a window manager that lets you shift and size your Mac’s windows using the mouse.

A grid that keeps things tidy

Instead of shunting windows around by hand, you get a grid. Drag a window towards an edge or corner and Lasso snaps it into place — half-screen, quarter-screen, or whatever chunk of the display makes sense for what you’re doing. The grid is visual, so you’re not guessing where things will land. You can also build custom layouts and save them. Got a regular two-panel setup for writing or coding? Set it once, then trigger it quickly. Those layouts can be exported and imported too, handy if you switch machines or want to share a working arrangement with someone else.

Move without touching the keyboard

A newer trick Lasso picked up is modifier-key dragging. Hold the keys down, click anywhere on a window, and move the mouse to reposition or resize it. No need to hunt for the title bar or the bottom-right corner. The same shortcut can also punt a window over to the next screen — useful when you’re plugged into a second display and want to send a full-screen reference doc across without letting go of the mouse. It all stays native to macOS, so there’s no extra layer of clunky interface stitched on top.

One shortcut to drag windows across monitors

If you run two or three monitors, Lasso earns its keep fast. Dragging a window to the next screen with one shortcut beats bouncing between Mission Control and a trackpad. The same goes for anyone who keeps two apps side by side for long stretches — writers with a reference doc open, coders with a terminal and a browser, spreadsheet folk comparing sheets. Keyboard shortcut fans will like the global triggers, but the modifier-key dragging means you don’t need to memorise much to start. If your Mac is on macOS 12 or later and runs an Intel or Apple Silicon chip, it’ll sit happily alongside whatever else you use.

Save your first one or two daily layouts

Start small. Pick one or two layouts you actually use daily and save those before building a whole library of grid setups. The custom layouts can be exported and imported, so once you’ve got a working arrangement, stash a copy somewhere safe — it takes seconds and saves redoing the work later.

Try the modifier-key dragging on a quiet afternoon, not mid-deadline. It takes a little muscle memory to click anywhere on a window and move it, but after an hour it feels natural. If a window won’t snap where you expect, check whether the grid is active for that display. Settings sync through iCloud, so your layouts follow you if you’ve got more than one Mac or reinstall later. Search for lasso for mac if you’re hunting for tips from other users, and keep the activation details from the package somewhere you can find them.
