Show HN: Smooth window arrangement in macOS restored

1 hour ago 1

In macOS Yosemite (10.10), Apple introduced "Window Snapping", which forced you into moveability gutters when you tried to arrange a window near another window, edge of the screen or dock. This tiny utility should help restore the functionality to previous smooth, natural movement.

Universal Binary. Compatibility: macOS 10.14.6 (Mojave) through macOS 15.x (Sequoia)

While I strive to maintain compatibility across all supported versions, please note that:

  • Different macOS versions may have subtle AXUI behavioral differences
  • Some system UI elements may not be detected as windows

Bug Reports & Issues: Feel free to open an issue if you encounter problems, but this is a free app and I likely won't be able to resolve your specific issue.

Your data stays yours. While this tool requires Accessibility permissions to function, which grants it the ability to: monitor mouse events system-wide, query window positions and properties, detect which application owns each window (and much more), there's no cause for concern because:

  • No network access: The application never connects to the internet
  • No data collection: No telemetry, analytics, or usage tracking
  • No data storage: Nothing is saved to disk except debug logs (when enabled)
  • Fully auditable: The entire source code is available for review
  • Minimal footprint: Only tracks window position changes during active dragging

You can verify all of this yourself by reviewing AppDelegate.m - the entire application logic is basically contained in a single file for easy auditing.
