CleanMachine's Space Visualizer renders a DaisyDisk-style sunburst chart of every folder on your Mac. Click any slice to drill down. Find exactly where your gigabytes went — folder by folder, all the way down to the specific file.
macOS 13+ · Apple Silicon & Intel · Starts at ~/
The Space Visualizer builds a tree of your filesystem starting from ~/. Each folder is a slice of the ring — the bigger the slice, the more storage that folder uses. Nested rings represent subdirectories: the inner ring is the parent, the outer ring shows its children.
Hover over any slice to see the folder name and size. Click a slice to drill into it — the chart re-centers on that folder, filling the entire visualization. A breadcrumb header lets you navigate back up the tree.
CleanMachine uses du -sk for block-based sizing — the same method as Finder's "Get Info." This is significantly faster than stat-based sizing for large directory trees and gives accurate on-disk sizes (accounting for actual block allocation, not just logical file sizes).
Each folder gets a color derived from a deterministic hash of its name — so the same folder always shows the same color across scans. This makes it easy to recognize specific folders visually as you drill in and out.
Complementary to the Space Visualizer is the Space Forecast feature — it records disk usage snapshots over time and uses linear regression to project when your disk will be full. If Space Visualizer shows you what's there now, Space Forecast shows you where you're headed.

DaisyDisk is an excellent app focused solely on the disk visualization. CleanMachine includes a similar visualization as part of a larger suite — Smart Scan, Duplicate Finder, App Uninstaller, Malware Scanner, and 20+ other features. If space visualization is the only thing you need, DaisyDisk is a fine choice at $9.99. If you want the full cleaning and security suite, CleanMachine includes the same visualization for $19.99 one-time.
Yes. The Space Visualizer can navigate to any mounted volume. Navigate up from ~/ to the root filesystem and you'll see all mounted volumes — external drives, network shares, and disk images.
Initial scan of ~/ depends on your storage size, but is typically 30–120 seconds. Once loaded, drill-down navigation is instant since child directory sizes are calculated during the initial scan pass.
