DeepClean: what stands out
A good fit for Mac users who want explained cleanup categories and developer-cache coverage.
DeepClean: strengths
- Safe/Review/Caution categories and item explanations
- Developer toolchain cleanup and content-matched duplicates
- Trash-first cleanup with deletion history
Considerations
- Unlimited cleanup requires a paid per-Mac license
- Category judgments still depend on your workflow
- Primarily category-based cleanup rather than a disk map
OmniDiskSweeper: what stands out
A good fit for Mac users who prefer a free size-sorted browser to a chart.
OmniDiskSweeper: strengths
- Largest-first file and folder browsing
- Open items or move them to Trash
- Official downloads include versions for older Macs
Considerations
- Column browsing rather than a graphical disk map
- Check the download requirements for your macOS version
- The cited overview does not document saved reports or duplicate matching
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 DeepClean?
A good fit for Mac users who want explained cleanup categories and developer-cache coverage. Free scan and first gigabyte of cleanup; unlimited cleanup listed at $39 once per Mac.
When should I choose OmniDiskSweeper?
A good fit for Mac users who prefer a free size-sorted browser to a chart. Free download from The Omni Group.
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.
