What is it?

PureMac is a macOS maintenance app that aims to replace paid cleaners such as CleanMyMac. It scans for system and user caches, logs, Trash, Xcode DerivedData and simulator data, Homebrew and npm/pnpm/yarn caches, and Docker images and containers, and it can run cleanup on a schedule once enabled. Its App Uninstaller uses a heuristic matcher to find related preferences, caches and containers left by an app, and an Orphan Finder surfaces leftovers from apps that are no longer installed.

The project also includes a Space Explorer for measuring folder sizes, a Duplicate Finder based on SHA-256 hashes, a Similar Photos tool that suggests visually similar images for manual review, and a Protection panel that reports the status of Gatekeeper, FileVault, the firewall and SIP. Homebrew cask updates can be checked from inside the app. Deletions by most tools go to the Trash, while dashboard cleanup, scheduled runs and CLI cleanup can remove data permanently.

PureMac is written in Swift for macOS 13 and later, is distributed as a signed and notarized DMG or through Homebrew, and is licensed under MIT. It requires Full Disk Access to read protected locations such as Mail downloads and Safari data.

Key features

  • 01Cleans system, user, Xcode, Homebrew, npm/pnpm/yarn and Docker caches
  • 02Uninstalls apps along with their related leftover files and finds orphaned files
  • 03Runs scheduled cleanup with a configurable interval and threshold
  • 04Finds duplicate files by content hash and similar photos for manual review
  • 05Includes a command-line tool with dry-run and JSON output
  • 06Shows status of Gatekeeper, FileVault, firewall and SIP without sending any data

Use cases

  • Freeing disk space on a Mac with a small SSD by clearing Xcode and Docker build leftovers
  • Removing leftover files after uninstalling macOS apps
  • Finding large or duplicate files inside a folder before deciding what to delete
  • Auditing basic macOS security settings without installing an antivirus tool

  • Some cleanup actions permanently delete data instead of moving it to the Trash.
  • Uninstall and related-file matching is heuristic, so results need review before removal.
