Estimate the biggest bucket
See whether space is mostly downloads, caches, simulators, app support files, Docker data, or other visible folders.

Free Mac Storage Scanner
Estimate what is filling your Mac, then get a no-cost cleanup decision. In SafeDisk Lite, tap start, approve macOS permissions when needed, and this page shows visible storage buckets first: downloads, screen recordings, app caches, Xcode data, simulator files, Docker data, and System Data suspects.
No file contents uploaded. SafeDisk Lite scans locally and skips system-only folders where macOS does not grant access.
Start the local scan from SafeDisk Lite. If you are in a regular browser, folder access may be limited or blocked.
What the scan is good for
Large files, System Data, Xcode, Docker, caches, and downloads.
Finder often hides the reason a Mac is full behind broad labels like System Data. SafeDisk groups browser-visible user paths by storage type, highlights estimated review scope, and separates quick free review from deep cleanup.
Review one candidate
Review a clearly identified large file or regenerable cache before deciding what to do next.
Pay only if worth it
If meaningful review-first storage remains, request the $29 Deep Cleanup from the scan result.
