+          WizTree-style disk space analyzer for macOS 15 or later (Apple silicon and Intel).
+
+          **Install:** unzip, move `MacTree.app` to Applications, and open it. The build is ad-hoc signed and not notarized, so macOS blocks the first launch. To allow it, go to System Settings › Privacy & Security and click **Open Anyway**. Or run `xattr -dr com.apple.quarantine /Applications/MacTree.app`.
+
+          For complete results, allow **Full Disk Access** when MacTree asks.
