| Cleanup workflow | Stage items in the Collector, then send the reviewed batch to Trash. | Pro moves selected files and app leftovers to Trash after review. |
| Reports and portability | The developer documents exporting maps as posters with Command-Shift-E. Keep that image as a reference; it is not a scan file that NullDisk can import. | The overview does not establish scan-report export. Preserve any app-removal decisions and rescan the same folders in NullDisk. |
Delve: what stands out
A good fit for Apple Silicon users on macOS 26+ who want two maps and staged cleanup.
Delve: strengths
- Treemap, sunburst, and file list
- Logical and on-disk measurement with filtering
- Quick Look, collector-to-Trash, and map image export
Considerations
- Requires macOS 26 or later
- Apple Silicon only in the current requirements
- A map export is a visual record, not a file backup
DissectMac: what stands out
A good fit for people who want free inspection and optional paid app/leftover cleanup.
DissectMac: strengths
- Free map, file search, and live monitor
- Filters for developer files and large storage categories
- Pro uninstaller and app-leftover cleanup
Considerations
- In-app clearing and uninstallation require Pro
- Treemap is the documented graphical view
- Confirm suspected leftovers belong to apps you no longer need
For a useful comparison on your own drive, match the scan root, access permissions, and size mode. Chart style changes how you explore the results; it does not by itself establish measurement accuracy.
Common questions
When should I choose Delve?
A good fit for Apple Silicon users on macOS 26+ who want two maps and staged cleanup. Vendor lists $4.99 once after a 14-day trial.
When should I choose DissectMac?
A good fit for people who want free inspection and optional paid app/leftover cleanup. Map, search, and monitor are free; Pro is listed at $12.99 once plus tax.
Will both apps show the same size?
Not necessarily. Match the scan root, permissions, exclusions, and logical/allocated-size mode. Hard links, APFS clones, snapshots, sparse files, and cloud placeholders can change totals. A reported size is not a guaranteed amount recovered after deletion.
