| Best fit | Apple Silicon users on macOS 26+ who want two maps and staged cleanup. | Mac users seeking an analyzer plus duplicate and photo cleanup tools. |
| Visualization | Treemap, sunburst, and file list | Sorted folder breakdown and cleanup lists |
| Platforms and requirements | macOS 26+, Apple Silicon | macOS 10.13+ (vendor requirements) |
| Pricing and editions | Vendor lists $4.99 once after a 14-day trial. | Free App Store download; full functionality via subscription or lifetime purchase. The subscription includes a seven-day trial. |
| Open source | No | No |
| Native macOS UI | Yes | Yes |
| Cleanup workflow | Stage items in the Collector, then send the reviewed batch to Trash. | Review each module’s action; ordinary cleanup and permanent shredding have different recovery implications. |
| 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 cited product page does not document scan export. Keep duplicate decisions and paths separately; hard-link accounting in NullDisk is not duplicate-content detection. |
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
Disk Xray: what stands out
A good fit for Mac users seeking an analyzer plus duplicate and photo cleanup tools.
Disk Xray: strengths
- Size-sorted folder scanner
- Byte-by-byte duplicate checks and similar-picture search
- App uninstaller, disk cleaner, and optional file shredder
Considerations
- Six modules serve different cleanup tasks
- Shredder operations are permanent
- Vendor limits content overwriting to supported HDDs, excluding SSD/APFS/network drives
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 Disk Xray?
A good fit for Mac users seeking an analyzer plus duplicate and photo cleanup tools. Free App Store download; full functionality via subscription or lifetime purchase. The subscription includes a seven-day trial.
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.
