Aion

Aion is a context-aware automatic exit tool for macOS.

Designed to clean up truly idle apps and reduce disruptions caused by switching lists, menu bars, and background processes via Cmd Tab. It doesn’t rely solely on a fixed countdown; instead, it checks before exiting whether the app is still downloading files, playing audio and video, using the microphone or camera, and prioritizes the standard macOS exit process to give unsaved content a chance to pop up a confirmation prompt. Users can set whitelists, blacklists, protection rules, and idle timeouts for different apps, and have rules automatically switch between work, meetings, and personal scenarios in macOS Focus mode. Aion runs locally, ensures app activity stays on Mac, supports Intel and Apple Silicon devices, and provides menu bar HUD, real-time resource visibility, installer DMG cleanup, windowless Dock app closure, and local automated protection interfaces, ideal for users who want to keep their desktop clean without missing important tasks.
