Recent macOS versions provide built-in window tiling, so many people can arrange two or four windows without another app. Rectangle remains relevant when its keyboard and snap behavior covers positions or habits the built-in tools do not.
Test the native baseline
Use the green-window menu, drag-to-tile behavior, and available keyboard commands on your current macOS version. Check halves, quarters, margins, multiple displays, and whether tiled windows enter a separate full-screen Space or remain on the desktop you expect. Review Desktop & Dock settings when edge dragging behaves unexpectedly.
If those actions are reliable and memorable, keep the native setup. Fewer global shortcuts and permissions mean fewer conflicts to maintain.
Test Rectangle for a specific gap
Rectangle’s official project describes moving and resizing windows with keyboard shortcuts and snap areas. Try only the commands you lack, such as repeated thirds or display movement, and check Accessibility access, excluded apps, shortcut conflicts, and windows that resist resizing.
Do not run both edge-trigger systems with overlapping gestures unless you understand which one owns the action. Disable one and retest when a snap produces the wrong result.
Neither option organizes windows by project or preserves a document’s identity. Wallo can add project grouping to existing windows, but it does not replace either tool’s geometry controls.
