Mac Cleanup Go is a preview-first TUI (Terminal User Interface) application designed specifically for cleaning macOS systems. Its main purpose is to help users reclaim disk space by safely removing unnecessary files while maintaining full control over what gets deleted. The tool scans known cache, log, and temporary file locations across applications and system directories.

The application scans known cache/log/temp paths across apps and tools in parallel, allowing users to preview items and exclude what they want to keep. It labels targets by impact level (safe, moderate, risky) and includes built-in scans for Homebrew, Docker, and old downloads using brew/docker output or last-modified time filtering. The tool supports multiple cleanup methods including trash (101 targets), permanent deletion (1 target), built-in scanners (3 targets), and manual guides (2 targets).

The tool operates through an interactive TUI interface where users can navigate categories, preview files, and selectively exclude items before deletion. By default, items go to Trash rather than being permanently deleted, with only the Trash category itself performing permanent deletion. Risky items start excluded by default, requiring users to explicitly include them in the preview page before deletion.

The primary benefit is recovering disk space while maintaining user control over the cleanup process. Use cases include regular system maintenance, freeing up space before software updates, and cleaning up after development work or application usage. The tool helps users avoid accidentally deleting important files through its preview and exclusion system.

The target audience includes macOS users who prefer command-line tools, developers who want to clean development environments, and anyone needing to reclaim disk space safely. Technical details include support for 107 total targets across System (7), Browsers (10), Development (35), Applications (52), and Storage (3) categories. The application requires Full Disk Access permission to clean restricted locations.
