Download DiskPrune
Notarized, Developer ID signed, and stapled. macOS opens it with a double-click — no Gatekeeper warning, no "Open Anyway" step.
macOS 14 Sonoma or later · Universal (Apple Silicon + Intel) · SHA-256 checksum
Installing DiskPrune
- Open DiskPrune.dmg — a window appears with the app icon.
- Drag DiskPrune.app into the Applications folder shortcut.
- Eject the disk image (drag it to the Trash, or press ⌘E).
- Open Finder → Applications → double-click DiskPrune.
- First launch: macOS asks if you're sure. Click Open.
That's it. No right-click tricks, no System Settings detour. The app is notarized.
Full Disk Access (optional)
DiskPrune scans without Full Disk Access, but some protected folders (Mail, Messages, Time Machine) only show byte counts — not filenames — unless you grant it. Grant it in System Settings → Privacy & Security → Full Disk Access.
Cleanup license
Scanning is always free. Moving items to Trash needs the lifetime license: $12 with code FOUNDING (applied automatically from our Buy buttons), $19 after the first 100 customers.
