A few things before you clean.
How can I clean Xcode DerivedData and iOS Simulator caches on Mac?
Use Safe Cleanup in LittleClean to review and clear Xcode DerivedData and iOS Simulator caches, including unavailable simulators. Xcode Archives and simulator devices can also be inspected in the separate, read-only Deep Analysis view.
Can LittleClean clear npm, pnpm, Yarn, and other developer caches?
Yes. Safe Cleanup finds known caches for npm, pnpm, Yarn, Bun, Deno, Gradle, Maven, and Cargo in your home directory. Review the entries before cleaning. Cache folders are kept; tools may need to download dependencies or rebuild caches afterward.
Can I use LittleClean to uninstall Mac apps and remove leftover files?
Yes. LittleClean finds an app’s associated caches, preferences, containers, and other leftovers. Uninstalled items are moved to Trash. After launching LittleClean once, you can also select apps in Finder and use Services → Uninstall with LittleClean, then review what to keep.
Does Deep Analysis delete my development tools or environments?
No. Deep Analysis is read-only. It shows installed tools, global packages, and home-directory disk usage, including Node.js version managers and Python environments. Use it to investigate storage and reveal locations in Finder; it has no delete action.
Is LittleClean free, and where can I download it for macOS?
LittleClean is free and open source under the MIT license. Download the latest ZIP from GitHub Releases. It requires macOS 14 or later and includes English and Simplified Chinese interfaces.
