FAQPage Schema
How do I clean up unused Homebrew packages on macOS to free up disk space?▼

To free up disk space by cleaning up unused Homebrew packages, run an audit that identifies orphaned formulae, outdated casks, and duplicate versions. The tool provides actionable, copy-pasteable commands like `brew cleanup` and `brew autoremove` to safely reclaim storage.

What is the best way to find outdated and orphaned Homebrew formulae?▼

The best way to find outdated and orphaned Homebrew formulae is by running parallel checks using `brew outdated` and `brew autoremove --dry-run`. This identifies software needing updates and dependencies no longer required, providing a clear report for system optimization.

Does Homebrew optimization affect my installed casks and formulae differently?▼

Yes, Homebrew optimization affects installed casks and formulae differently by running `brew leaves` for formulae and `brew list --cask` for casks. It detects unused, outdated, and duplicate packages across both, providing specific cleanup commands for each package type.

How do I check macOS Homebrew system health and disk usage?▼

You can check macOS Homebrew system health and disk usage by running `brew doctor` alongside cleanup dry-runs. This analyzes your installation for potential problems, identifies large packages and stale downloads, and reports general system health to ensure efficient package management.

Can I preview Homebrew cleanup actions before removing files?▼

Yes, you can preview Homebrew cleanup actions before removing files by executing `brew cleanup --dry-run` and `brew autoremove --dry-run`. These commands analyze your installation and provide actionable recommendations without actually deleting packages or freeing disk space.
