Rectangle
Rectangle is a lightweight macOS window manager by Ryan Hanson that lets you move and resize app windows with shortcuts and snap areas.
What is Rectangle?
Rectangle is a macOS window management utility published by Ryan Hanson. It helps users quickly move and resize application windows using keyboard shortcuts, menu bar controls, and drag-based snap areas. The app is commonly used by people who want faster tiling-style window organization without replacing the standard macOS desktop experience. It integrates with macOS accessibility permissions so it can control other app windows, which is a normal requirement for this type of utility. Rectangle is widely known as a simple, focused tool for arranging windows into halves, thirds, quarters, and other common layouts. Users typically encounter it as a menu bar app that runs in the background after login and responds to configured hotkeys. It is generally a legitimate productivity utility rather than a system component.

Safety overview
Status: Safe
Rectangle is a legitimate window management app from Ryan Hanson. It needs macOS Accessibility permission to move and resize other apps' windows, which is expected for this category of utility. That permission gives it broad control over window interactions, so it should be installed only from the official site or the publisher's verified distribution sources.
Recommendation: Keep it if you use keyboard-driven window management or snap layouts. Remove it if you no longer use its shortcuts or prefer macOS built-in window arrangement features, especially since it may run at login for convenience.
