Häufige Fragen
What is the best alternative to Klarity Disk for Mac?
For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. Klarity Disk users who want treemap views and paid pricing will feel at home within minutes.
Is there a free alternative to Klarity Disk?
Yes — GrandPerspective and Disk Inventory X are free and open source with genuine treemap analysis. They lack NullDisk's collector workflow and sunburst map, but they find the biggest hogs fast.
How do I switch from Klarity Disk to NullDisk?
Note the largest folders Klarity Disk flagged, then run the same scan in NullDisk and rebuild the cleanup in its removal collector. The full walkthrough is on our switching guide.
Unterm Strich
Klarity Disk is a capable tool for treemap fans on macOS. But if you want the whole job — see, stage, and safely remove — done natively on a modern Mac, NullDisk is the upgrade. Wechselanleitung →
