Could you build this?
No Developing a macOS tiling window manager requires reverse-engineering and hooking into undocumented macOS SkyLight/CoreGraphics private APIs, managing accessibility event loops, and deep systems engineering in Rust/Objective-C.
What it would actually take: The tool must interact with macOS's private WindowServer and Accessibility APIs (HIServices, AXUIElement, SkyLight framework) using Rust with Objective-C FFI bindings. It requires building a custom dynamic window layout engine, intercepting global hotkeys, tracking window focus/space change notifications, and handling macOS SIP restrictions and permissions. Deep low-level macOS internals expertise is essential, as the necessary OS interfaces are intentionally undocumented and frequently break across macOS releases.
