A macOS disk-usage utility that maps storage and ranks cleanup suggestions by the space they can actually recover.

Landing page captured for the 2026-11-02 issue.

For: Mac users managing disk space and Xcode files
Worth noticing: The developer example marks 38.2 GB of Xcode DerivedData safe to reclaim, while old archives need review.

Field notes

The page describes three ways to inspect storage: a sunburst for drilling down, a treemap for spotting large files, and a list for precision. Its developer example separates 38.2 GB of Xcode DerivedData and 9.4 GB of device-support files from 6.8 GB of old archives, which it marks for review. Pro is listed with full history, scheduled scans, a menu bar extra, and bulk cleanups.
