Map the workspace you actually use
Write down which display holds your main task, reference material, and communication apps. Start with two or three positions you use every day rather than trying to memorize every possible grid.
Rectangle is a Mac window-management app. Compare its current layouts and shortcuts with the built-in tiling options available on your macOS version.
Choose a few useful layouts
A practical starting set might be a large primary window, a side-by-side pair, and a temporary reference window. Use names or shortcuts that are easy to remember. Avoid assigning many overlapping hotkeys before you know which layouts are worth keeping.
Plan for display changes
MacBooks move between desk, meeting room, and travel setups. Decide where a window should go when an external display is disconnected, and test the behavior before an important presentation. Full-screen apps and separate Spaces may behave differently from ordinary windows.
Review permissions and shortcuts
Window-positioning tools may need Accessibility permission to control windows. Grant only the permission requested by the app you intentionally installed, and review the app’s current explanation. If a shortcut stops working, first check for a conflict with another app.
