First preview release of MacDirStat, a native, read-only macOS disk visualizer.

Download and install

  1. Download MacDirStat-1.0.0-macos-universal.zip below.
  2. Extract the ZIP and drag MacDirStat.app to Applications.
  3. Launch the app, choose a folder or disk, and click Search.

Requires macOS 14 Sonoma or later. The app contains both Apple Silicon and
Intel builds. No Xcode or developer account is needed to run the download.

This preview is ad hoc signed, not Developer ID signed or notarized. macOS
may block the downloaded app. See Apple’s guidance for opening an app from an
unknown developer, or
build from source.

Included

  • A synchronized directory tree and treemap, colored by file type.
  • On-disk sizes, logical content lengths, file paths, and folder shares in the inspector.
  • Fast mode to measure application bundles without retaining their internal file trees.
  • Hard-link accounting across ordinary files and Fast mode packages.
  • Cancellation with browsable partial results and explicit incomplete totals.
  • Open, Reveal in Finder, and Copy Path actions. No delete, move, or cleanup actions.
  • Local scanning without accounts, analytics, or scan uploads.

Known limitations

  • Network volumes aren’t supported.
  • Unreadable entries and cancelled scans leave totals as lower bounds.
  • APFS clones are counted separately; shared blocks can therefore be counted more than once.
  • Resource forks, extended attributes, and filesystem metadata are excluded from the totals.
  • Reported sizes are not a guarantee of reclaimable disk space.
  • Automated tests pass on macOS 15 for both architectures; manual testing across every supported macOS version is not yet complete.

Verification and source

SHA256SUMS.txt contains checksums for both ZIPs. To verify both downloaded files:

shasum -a 256 -c SHA256SUMS.txt

The debug-symbols ZIP is only needed for crash diagnosis, not installation.

Report a bug with your macOS version,
CPU architecture, scan mode, and reproduction steps.
