Is There a TreeSize for Mac?
The short answer
No. TreeSize is a Windows application from JAM Software and there is no macOS version. Diskaroo gives you the same core job on a Mac, a drill-in treemap of where your space went, and the same purchase covers Windows and Linux too.
What Diskaroo gives you on Mac
- +A native Mac app, which TreeSize does not offer.
- +A squarified treemap with drill-in and breadcrumbs for finding what is actually large.
- +Byte-exact duplicate detection in the same scan, with a deterministic three-pass match.
- +Consumer pricing: one purchase covering Mac, Windows and Linux rather than per-seat professional licensing.
What TreeSize genuinely does well
- ·TreeSize is the IT-administrator standard on Windows, with network share scanning and NTFS-specific reporting Diskaroo does not attempt.
- ·Its reporting and export options are far deeper than ours.
- ·For managing Windows servers and shares, it is the right tool and Diskaroo is not a replacement.
| On Mac | Diskaroo | TreeSize |
|---|---|---|
| Native Mac app | Yes | No, Windows only |
| Network share scanning | Limited | Extensive, its core strength |
| Duplicate detection | Byte-exact, built in | In higher tiers |
| Licensing | One purchase, three platforms | Per-seat, scales with users |
When you should stay put
For Windows administration, TreeSize is the better tool and this page is not trying to move you off it. The gap it fills is that TreeSize has no Mac build, so a Mac in your setup needs something else entirely.
Common questions
Does TreeSize work on Mac?
No. TreeSize is Windows-only. JAM Software has not released a macOS version.
What is the best TreeSize alternative for Mac?
GrandPerspective and DaisyDisk are the well-known Mac-only options. Diskaroo is the one that also runs on Windows and Linux, so a mixed setup only needs one tool.
Can Diskaroo replace TreeSize for IT work?
No. If you are scanning network shares and producing reports for a Windows estate, TreeSize Professional does things Diskaroo does not. Diskaroo is aimed at people cleaning up their own machines.
