Frequently asked questions

Is Delve worth it?

Delve is worth a look if you like mixed views and paid pricing on macOS. An honest APFS-aware treemap plus sunburst with collector cleanup. For a native Mac map with a staged cleanup workflow, compare it against NullDisk before deciding.

Is Delve safe?

Delve is as safe as its workflow: it visualizes usage and deletes on your command. Whatever you choose, prefer tools that stage deletions or use the Trash — which is exactly how NullDisk's collector works.

Does Delve work on Apple Silicon?

Yes — Delve runs on modern Macs, including Apple Silicon. If nativeness matters to you, NullDisk is built SwiftUI-first for macOS 14 and up.

Bottom line

Delve: both treemap and sunburst views with APFS-aware measurement — but newer entrant — fewer reviews and community resources. Weigh that trade honestly against NullDisk's native map, staged collector, and zero-data promise.
