Why this silently grows
Each backup may include app data, photos metadata, and system state. Device upgrades and repeated manual backups can leave multiple large backup sets in ~/Library/Application Support/MobileSync/Backup.
How Free Mac Space finds it
Free Mac Space has a dedicated iOS Backups category that scans MobileSync backup roots and shows their aggregate footprint, so users can evaluate how much local history they are keeping.
How cleanup is handled
By default this category is analysis-only. The app helps you identify stale backup sets and their size, then you can remove unnecessary backups through Apple-managed tools with better confidence.
Safety boundary
iOS backups are treated as high-risk because they may be the only recoverable copy for a device. The product avoids direct cleanup to reduce accidental data loss.
Paths covered in Free Mac Space
- ~/Library/Application Support/MobileSync/Backup
Recommended monthly check
- Map backup folders to active devices before deleting anything.
- Keep at least one recent valid backup per critical device.
- Use scan reports to document storage reclaimed from retired backups.
