Precision storage control, absolute safety.
CleanYourMac Space combines low-level macOS Mach kernel APIs with a modern SwiftUI visual interface to give you complete mastery over your Mac disk space.
Interactive Squarified Storage Treemap
Visualizes your entire Macintosh HD as proportional rectangles. Drill down into nested subdirectories, zoom into bloated folders, and inspect exact byte distributions with instant hover tooltips.
Developer Storage Mode
Specialized cleaners for Xcode DerivedData, build archives, iOS Simulators, Docker VM disk images, Ollama / LM Studio AI model weights, node_modules, and Gradle compilation caches.
Bundle-ID App Leftovers Uninstaller
Scans /Applications and uses exact bundle identifiers to discover orphaned Application Support databases, Caches, Preferences plists, Containers, and Saved States left behind after deleting apps.
Staged 3-Tier Duplicate Finder
Finds byte-exact duplicate copies without grinding your SSD to a halt. Uses File Size grouping, fast 4KB partial header/tail hashing, and streaming SHA-256 digests.
Trash-First Safety & TOCTOU Protection
All cleanups default to macOS Trash with instant undo. Atomic pre-flight validation verifies file existence, inode identity, and permissions immediately before trashing to eliminate TOCTOU risks.
Native Mach Kernel System Monitor
Live telemetry querying Mach host CPU processor info, Unified Memory (wired, active, compressed), and storage volume capacity without battery drain.
