Clear Every Cache
on Your Mac.

User Caches (~/Library/Caches)

This is the biggest single cache folder on most Macs. Every app stores its own subdirectory here — Spotify, Slack, Chrome, Mail, Xcode, and hundreds more. These caches were designed to speed up apps, but after years of use they grow without limit. It's perfectly safe to clear them — each app will rebuild its cache on next launch.

Browser Caches

Each browser maintains its own separate disk cache for web images, scripts, and page data. On a heavily used Mac with multiple browsers:

• Chrome — ~/Library/Caches/Google/Chrome/Default/Cache
• Firefox — ~/Library/Caches/Firefox/Profiles/
• Safari — ~/Library/Caches/com.apple.Safari
• Edge — ~/Library/Caches/Microsoft Edge/Default/Cache
• Brave — ~/Library/Caches/BraveSoftware/

Combined, these often reach 3–8 GB. CleanMachine clears all of them in one scan — with a warning if any browser is still open (to prevent database corruption).

System Logs

macOS and every app generates log files in ~/Library/Logs and /private/var/log. These are for debugging and are safe to clear. On a Mac that's been running for years, logs can accumulate to 2–5 GB.

Language Packs (.lproj files)

Every macOS app ships with translation files for 40+ languages. If you only use English (or one language), those other .lproj folders are pure waste — often 100–500 MB per large app. CleanMachine identifies and removes all non-active language packs.

Developer Caches

If you're a developer, the biggest cache culprits are usually:

• Xcode DerivedData (~10–30 GB on an active project) — rebuild artifacts that regenerate on next build
• iOS Simulators (~5–20 GB) — cloned iPhone/iPad images for testing
• npm cache (~1–5 GB) — Node.js package cache in ~/.npm/_cacache
• pip cache (~500 MB–2 GB) — Python package cache
• Gradle cache (~2–10 GB) — Java/Android build cache in ~/.gradle/caches
• Homebrew cache (~500 MB–3 GB) — downloaded package installers in ~/Library/Caches/Homebrew
