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
Klarity Disk: what stands out
A good fit for Mac users who prefer rectangular views and age-based browsing.
Klarity Disk: strengths
- Treemap and icicle layouts with age-based colors
- Large Files list and hidden Library visibility
- Trash-only removal with extra confirmation for large folders
Considerations
- No sunburst in the documented view selection
- Age indicates modification history, not whether a file is unnecessary
- System-folder guards intentionally limit removal

Common questions
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.
When should I choose Klarity Disk?
A good fit for Mac users who prefer rectangular views and age-based browsing. Vendor lists $6.99 once through the Mac App Store.
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.
