Designed to Prevent Accidental Deletion
Generic Mac cleaners promise "one-click magic" and risk breaking developer environments or erasing critical system caches. DiskWarren is engineered around explicit user review, macOS Trash-first reversibility, and immutable APFS protection.
1. macOS Trash-First Deletion
DiskWarren never uses destructive raw unlinks (rm -rf) on user files. Cleanups route through macOS NSFileManager.trashItem, allowing you to instantly restore any item from your Mac's Dock Trash with "Put Back".
2. Protected System Whitelist
Our safety gate enforces an immutable hardcoded blocklist that physically rejects scans and modifications inside Apple SIP (System Integrity Protection) volumes, including /System, /usr/bin, and critical kernel extensions.
3. Safe Rebuilding Guarantee
DiskWarren targets only 100% reproducible developer artifacts (Xcode DerivedData, CocoaPods, node_modules, Cargo build targets, and Docker build caches). Source repositories, git commits, and uncommitted code are strictly whitelisted and never touched.
4. 100% Air-Gapped Local Operation
Zero telemetry. No file paths, directory structures, code names, or personal documents are ever uploaded to cloud servers. DiskWarren operates fully offline without requiring network connectivity.
Explicit Review Before Every Action
DiskWarren provides granular itemized previews displaying the exact file path, size, and category. You can uncheck individual items or entire directories before confirming cleanup.
