How to Clean Homebrew Cache and Remove Orphaned Formulas on Apple Silicon

Homebrew is the package manager missing from macOS, but on Apple Silicon Macs (where packages are installed to /opt/homebrew instead of /usr/local), it hoards download archives aggressively. Whenever you run brew upgrade, Homebrew downloads compiled bottle tarballs and keeps old versions cached in case you want to downgrade.

Over a year of installing tools like Node, Python, FFmpeg, and Postgres, your Homebrew cache in ~/Library/Caches/Homebrew/ can quietly swell to 25 GB. Here is how to keep it lean.

Essential Terminal Commands for Homebrew Cleanup

Open Terminal and run the following three commands:

• brew cleanup -s: Removes all cached bottle downloads and purgeable lockfiles.
• brew autoremove: Uninstalls formulas that were originally installed as dependencies but are no longer required by any active tool.
• rm -rf $(brew --cache): Empties the physical Homebrew download cache directory completely.

MagicMacCleaner integrates this maintenance into its Expert Package Manager panel, allowing you to trigger Homebrew, Cargo, and pip cache purges simultaneously.

Mobile Developer Workflow: Free Up Storage on Physical Test iPhones

While clearing Xcode caches, simulator runtimes, and build containers frees vital space on your Mac, physical iOS test devices rapidly become clogged with test builds, crash artifacts, diagnostic screen recordings, and QA screenshots. Keeping your physical testing hardware lean is essential for rapid on-device debugging and reliable deployment.
