Important — please back up your Mac before running MacJanitor. MacJanitor deletes files. Every proposed deletion is shown to you for review before it runs, and the AI is conservative by default, but deletion is permanent and the responsibility for proceeding is yours. We strongly recommend a current Time Machine backup before any cleanup. See our Terms for the full data-loss disclaimer.

Validated in real use. 130 GB recovered in 15 minutes during a single disk-pressure incident — at 2.1 GiB free out of 460 GiB. The cleanup involved Xcode iOS simulator runtimes the user didn't know existed, orphaned Squirrel.Mac update caches, and Audible audiobooks safely re-downloadable. None of those were findable via macOS Settings → Storage.

What MacJanitor does

Scans hidden disk hoarders that macOS Settings doesn't surface — Xcode iOS simulator runtimes, Adobe asset caches, ShipIt updater orphans, iOS device backups, Mac Catalyst app containers.
Sends only file paths and sizes to Claude (never file contents) for contextual analysis based on your stated user profile (developer, designer, casual user, etc.).
Returns a categorized cleanup plan: safe-to-delete (caches), surgical (path-confirmed), inspect (yes/no questions for ambiguous folders), and keep (never touch).
Conservative-by-default — when in doubt between "delete" and "ask," it asks. The user can escalate; they can't undo a delete.

Privacy promise

File contents NEVER leave your Mac. Only file paths and sizes are sent for analysis.
