DiskInsight, a byte-by-byte map of your Mac
A local Mac disk utility for visualizing storage, finding content-based duplicates, clearing developer caches, and uninstalling apps more completely.
- For
- Mac users with crowded drives, duplicate files, or developer caches
- Worth noticing
- The duplicate finder hashes file contents and groups copies even when filenames and folders differ.
Field notes
The utility presents storage through nine switchable views, from a whole-drive treemap to folder-depth diagrams and sortable lists. Its duplicate workflow hashes file contents, allowing differently named copies to be grouped, while the cleanup section calculates reclaimable bytes before review. The page specifically names 20 curated developer-cache locations and says cleanup sends selected items to the Trash. A $9.99 lifetime license is advertised for macOS 14 and later.
