SpaceHound
Find out where your disk space went. SpaceHound scans a disk in seconds, shows the biggest folders and files, and tells you which ones are safe to clean up.
What it does
It focuses on large files that belong to you and that you can safely remove.
Tree
Folders sorted largest first, using the real on-disk size.
Largest Files
The top 500 files, filterable by size, type and age, with a note on what each one probably is.
Map
A treemap coloured by what things are. Double-click to drill in.
Changes
See what grew or shrank since an earlier scan.
Duplicates
Find files with identical contents, only when you ask it to.
Categories
Caches, Xcode data, Docker, AI models and more, each with a note on whether it's safe to remove.
Saved scans
Reopening is near-instant, and macOS's change log keeps the results up to date.
Safe clean-up
Quick Look, Reveal in Finder and Move to Trash with confirmation. It never permanently deletes, and never touches system files.
Private by design
Scans read only file names, sizes and dates. Nothing leaves your Mac. File contents are read only by the Duplicates tab, and only when you start it.
How to install
This build isn't notarised by Apple yet, so macOS asks you to approve it once.
- Open the SpaceHound .dmg and drag SpaceHound to Applications.
- Open SpaceHound. macOS will refuse the first time.
- Go to System Settings → Privacy & Security, scroll down and click Open Anyway next to SpaceHound.
- When SpaceHound asks, turn on Full Disk Access so it can measure every folder. It still works without it, but skips some folders.
On a company-managed Mac, IT policy may block apps that aren't notarised, or block Full Disk Access.
