MagicQuit

MagicQuit monitors running applications on macOS and automatically closes those that have been idle, helping to keep the desktop uncluttered and free up memory and battery resources. It operates entirely offline, requiring no network access or data transmission, and runs with negligible CPU overhead. The tool respects unsaved work by prompting the user before quitting an app that has pending changes, and it never terminates core system services such as Finder or Spotlight.

Users can customize its behavior through a menu‑bar interface, where individual apps can be excluded by unchecking a box, ensuring that programs the user wants to keep running are left untouched. The exclusion list persists, preventing those applications from being closed in future sessions.

MagicQuit is released under an open‑source license, is free of charge, and supports macOS version 13 and newer. Its lightweight design and straightforward functionality make it suitable for anyone looking to reduce background app clutter without manual intervention.
