DaisyDisk 4.32

The premier disk space analyzer for macOS. The late 2025 'v4.32' update is fully optimized for macOS Tahoe, featuring improved discovery of 'System Data' (formerly 'Other' storage), keyboard-driven navigation, and native support for APFS dataless files. Its interactive sunburst diagram allows for lightning-fast drill-downs into massive directories. While its $10 price is widely considered the best value in the industry, users on a strict zero-budget often turn to GrandPerspective or the terminal-based ncdu.
