Diskfern 1.0: Understand what’s using your Mac’s storage

Diskfern 1.0.0 helps you see what is taking up space, understand what can be safely removed, and choose what happens to files before anything is deleted.

See your storage clearly

• Scan your Mac, Home folder, or a folder you choose, with live progress and the option to stop a scan.
• Explore storage in Treemap, List, and Sunburst views. Switch views without losing your current place.
• See on-disk sizes, file kinds, and folder contents, then search and filter scan results to find large files, developer artifacts, downloads, and other space users.
• Reopen a saved scan quickly and keep its results updated as files change.

Find items worth reviewing

• Smart Highlights groups common storage items into categories and labels them Safe, Review, or Protected to help you decide what to inspect.
• Inspect files and folders with details, Quick Look previews, and actions to reveal an item in Finder or copy its path.
• Review Trash contents and see their sizes before permanently removing anything.

Clean up with control

• Stage selected items in the Collector and review the list before taking action.
• Move items to the Trash by default, or explicitly choose immediate deletion where supported.
• Confirm destructive actions with Touch ID or your Mac password.
• Uninstall eligible apps after reviewing their disk usage; running apps, system apps, and Diskfern itself are protected.

Built for macOS

• Check Full Disk Access and other permissions in Settings, with guidance when macOS blocks access to protected folders.
• Use Disk Advisor on compatible Macs to ask questions about a selected item. Its analysis runs on your Mac using Apple’s on-device model.
• Receive signed app updates through Diskfern’s built-in updater.

Some protected locations may not be readable until you grant macOS permissions. Disk Advisor requires a compatible Mac and Apple Intelligence support.
