Start with the browser scan
Mac storage cleanup works best when the first pass estimates the largest user-owned storage buckets before deleting anything risky. The browser scan turns that into a short cleanup list.
- Open SafeDisk in Chrome or Edge
- Approve browser folder access when prompted
- Use the free scan first, then buy the $29 deep cleanup only if useful space remains
Usually safer cleanup candidates
- Old DMG or ZIP files after confirming they are not needed
- Regenerable app caches after closing the app
- Clearly identified build artifacts
Review before deleting
- Unknown Library folders
- Photos, Mail, Messages, and app support data
- Local snapshots before understanding Time Machine state
What to do next
After you find the largest folders, sort each item into three buckets: safe to remove, review first, and do not touch. That keeps the cleanup focused on recoverable space instead of random Library deletion.
Want this checked against your scan?
Run the free scan first. If meaningful review-first storage remains, request the $29 deep cleanup for safe, review, and do-not-touch buckets.
Still full after the browser scan?
Start with the browser scan. If the scan shows review-first storage that still needs judgment, send one request for the $29 Deep Cleanup next step.
