Częste pytania
What is the best alternative to diCleaner for Mac?
For most Mac users it's NullDisk: native SwiftUI, a radial sunburst map, a staged removal collector, and zero data collection. diCleaner users who want list views and free pricing will feel at home within minutes.
Is there a free alternative to diCleaner?
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 diCleaner to NullDisk?
Note the largest folders diCleaner flagged, then run the same scan in NullDisk and rebuild the cleanup in its removal collector. The full walkthrough is on our switching guide.
W skrócie
diCleaner is a fine free tool for list 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. Przewodnik migracji →
