Common questions
When should I choose DaisyDisk?
A good fit for Mac users who want a sunburst, cloud connections, and snapshot tools. One-time license; free trial. Check vendor pricing and direct/App Store edition differences.
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.
