System Data 116GB: AI deletion judgment for Mac storage
A practical first-pass checklist for System Data 116GB on M1. The goal is to recover space without deleting the folder that proves expensive to rebuild.
Run the free Mac scan before deleting.
The Mac scan reads storage metadata locally, then shows the largest visible buckets and the files that need an AI delete / confirm / protect judgment.
Avoid random Library deletion
System Data and full-disk reports are labels, not a deletion judgment. The same number can hide caches, developer tools, local snapshots, downloads, or app support data.
First read-only checks
Use read-only size checks first, classify the largest folders, and move uncertain items to Trash only after you know what generated them.
du -sh ~/Library/* 2>/dev/null | sort -h | tail
tmutil listlocalsnapshots /AI would usually mark delete
- Old installers or archives already backed up
- Regenerable app caches after the app is closed
- Developer caches with a clear rebuild path
AI would mark confirm or protect
- Unknown Library folders
- Photo, mail, or message stores
- Project folders and app support data without an owner review
