What it does
Scans at full speed
A parallel fts(3) traversal walks the filesystem natively and streams results as it goes, so the tree fills in while the scan is still running instead of blocking on a spinner.
Three views, always in sync
A size-sorted outline, a flat breakdown by file extension, and a labeled treemap. Select or hover in one and the others follow.
Delete straight to the Trash
Remove what you find with ⌘⌫ or the context menu. Totals across every view recompute instantly — no rescan — and confirmation is on by default.
Honest about what it skipped
When macOS blocks a folder, AppleTree tells you why — privacy-protected, system-owned, or plain permission denied — and only suggests Full Disk Access when it would actually help.
Notices changes underneath it
Files deleted or moved by Finder, Terminal, or anything else are flagged live in a completed scan, so the numbers on screen stay trustworthy.
Counts things once
Hardlinks, APFS clones, and firmlinked directories are de-duplicated, and a scan stays on one device — so totals reflect real disk usage.
Nothing leaves your Mac
AppleTree has no account, no analytics, and no network calls. It runs in the macOS App Sandbox and reads only the folders you point it at. Scan results live in memory and are discarded when you close the window.
