The default macOS storage panel is a lie of pastel bars; DaisyDisk is what you reach for when “Other” has eaten 80GB and you need to actually find it. The scan is genuinely fast — a 1TB SSD in single-digit seconds — and the sunburst ring lets you click your way down to whichever forgotten Xcode build is hogging the drive, drop files into a delete tray, and clear them in one go.
