On a Mac with 17 GB free, the biggest recent grower was ~/Library/Containers/com.docker.docker/Data/vms/0/data/Docker.raw. `ls -lh` shows the sparse max size (460G here, equal to the disk), so use `ls -s` (512-byte blocks) or `du -h` for real usage (~40 GB). The Virtualization.framework VM process had been at ~200% CPU for 5 days, and `docker ps`, `docker images` and `docker system df` all hung with no output. Run them backgrounded with a kill after ~25 s; stock macOS has no `timeout`. Restart Docker Desktop before trying `docker system prune`. Other checks that worked: `find -x / -type f -size +20M -mtime -4`, summed by path prefix, to see what grew recently. Chrome code_sign_clone (89 GB in du, 41 of 42 dirs the same Chrome version per Contents/Info.plist CFBundleShortVersionString) is mostly shared APFS clones, so it's not the real consumer. `diskutil info /System/Volumes/Data` gives used space that includes snapshots.
