Lasso - Window Manager
Lasso is a macOS window manager that helps you move, resize, and arrange app windows quickly with grid layouts, shortcuts, and multi-monitor support.
What is Lasso - Window Manager?
Lasso is a native macOS window manager designed to help users organize open windows faster and keep desktop layouts under control. It is built for people who work with several apps at once and want a quicker way to snap, resize, and position windows across one or more displays. Lasso supports drag-based window placement with a grid, custom layouts for common workspace setups, keyboard shortcuts for faster arrangement, and tools for moving or resizing windows without manually lining everything up. It also includes features aimed at restoring a more consistent working layout when switching between tasks or monitor setups. Published by Ivan Sapozhnik, Lasso fits best into productivity-focused Mac workflows where screen space management matters every day.

Safety overview
Status: Mostly safe
Lasso is legitimate window-management software for macOS. Apps in this category commonly need Accessibility access so they can move and resize other app windows, and some users may also enable background operation or launch-at-login for convenience. That level of access is normal for a window manager, but you should grant permissions only if you use the app and download it from the developer's official source.
Recommendation: Keep Lasso if you use it to manage window layouts or speed up multitasking on your Mac. If you no longer use its snapping, layout, or shortcut features, you can remove it and revoke its Accessibility permission without affecting macOS beyond losing those window-management tools.
