أسئلة شائعة
What is the best alternative to Disk Graph for Mac?
For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. Disk Graph users who want mixed views and paid pricing will feel at home within minutes.
Is there a free alternative to Disk Graph?
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 Disk Graph to NullDisk?
Note the largest folders Disk Graph flagged, then run the same scan in NullDisk and rebuild the cleanup in its removal collector. The full walkthrough is on our switching guide.
الخلاصة
Disk Graph is a capable tool for mixed fans on macOS + iOS. But if you want the whole job — see, stage, and safely remove — done natively on a modern Mac, NullDisk is the upgrade. دليل الانتقال →
