Delve / Comparisons
WizTreeMac brings the familiar tool to macOS. If you are deciding whether to use it or another Mac disk analyzer, start with the current release and the workflow you need.
Khaos Studios makes Delve. This comparison draws on the official product documentation linked below.
WizTree’s developer introduced WizTreeMac in its September 16, 2026 release notes. The Mac app requires macOS 12 or later. Older advice that WizTree is Windows-only is now out of date.
Start at the official WizTree download page. The developer says existing Supporter Codes work across Windows and Mac, and describes most Windows functionality as available in the first Mac release.
WizTree’s Windows scanning advantage is associated with reading NTFS’s Master File Table. WizTreeMac uses macOS directory-enumeration APIs instead. That means a Windows benchmark is not a Mac benchmark, even when the product name is the same.
The developer also documents differences in permissions, portable mode, and command-line syntax. Mobile-device scanning through MTP is not supported in the first Mac release. Check the official platform comparison if one of those features is part of your workflow.
| App | Consider it for | Requirements or limits |
|---|---|---|
| WizTreeMac | Continuity with WizTree, file lists, treemap, and export workflows | macOS 12+; free for personal use, paid commercial licensing |
| Delve | Treemap and sunburst views, Quick Look, and a Collector | $4.99 once or free through referrals; 14-day trial; macOS 26+, Apple Silicon |
| GrandPerspective | Free, open-source treemap with filters and saved scans | Current release: macOS 14+, Intel and Apple Silicon |
| DaisyDisk | Sunburst navigation and connected cloud accounts | $9.99 direct; macOS 10.13+, Intel and Apple Silicon |
Choose by features you will use. We have not published a controlled performance comparison between Delve and WizTreeMac.
If you already rely on WizTree’s lists, filters, or export workflow, evaluate its Mac edition first. Familiar controls can make the transition simpler, and the developer documents how Windows and Mac scan exports work together.
For workplace use, check the commercial license. A free personal-use download is not the same as permission to deploy it across a business.
Delve is an alternative when you want to explore storage in both rectangular and radial views, preview the files you find, and collect selected items for a reviewed move to the Trash. Its 14-day trial gives you a way to evaluate that workflow with your own storage.
Start with WizTreeMac if keeping your existing WizTree workflow matters most. Try Delve if you prefer its two visual views and Collector, and your Mac meets its requirements. Use the same folder and scan scope to make the comparison useful.
Yes. The developer announced WizTreeMac in the September 16, 2026 release notes. Its first release requires macOS 12 or later.
WizTree’s official download page offers free personal use and paid commercial licensing. Review the current terms for your intended use.
The developer says Supporter Codes work on both Windows and Mac, so an existing code does not need to be repurchased solely for the Mac app.
The platforms use different scanning methods. WizTreeMac uses macOS directory-enumeration APIs rather than the NTFS Master File Table. We have not published a controlled benchmark comparing the platforms or Delve.
