180G /Users/txmmy/Library/Containers
已经抓到主犯了。~/Library/Containers 占 180G，这基本就是 System Data 变大的核心来源之一。这个目录是沙盒 App 的数据，不能整目录乱删，但可以继续定位是哪几个 App 在吃空间。
再查一下
du -sh ~/Library/Containers/* 2>/dev/null | sort -h | tail -30

40G /Users/txmmy/Library/Containers/com.tencent.xinWeChat
100G /Users/txmmy/Library/Containers/com.docker.docker
所以，破案了
system data 中占用最大的是：
100G ~/Library/Containers/com.docker.docker
40G ~/Library/Containers/com.tencent.xinWeChat
32G ~/Library/Containers/com.utmapp.UTM
接着按照这个顺序去清理
- docker
查看docker占用明细
docker system df
txmmy@txmmydeMacBook-Pro my-python-projects % docker system df
TYPE TOTAL ACTIVE SIZE RECLAIMABLE
Images 27 22 21.06GB 10.91GB (51%)
Containers 40 6 1.82GB 1.819GB (99%)
Local Volumes 7 4 305.7MB 303MB (99%)
Build Cache 30 0 4.935GB 4.935GB
txmmy@txmmydeMacBook-Pro my-python-projects %
先按照以下指令清理，清理了20g左右
docker container prune
docker image prune -a
docker builder prune -a
这就是 Docker Desktop 的 Linux 虚拟机磁盘。docker system df 只看到约 28G 有效内容，说明虚拟磁盘已经膨胀，清 Docker 对象后不一定自动缩回 macOS 占用。
txmmy@txmmydeMacBook-Pro my-python-projects % du -sh ~/Library/Containers/com.docker.docker/Data/* 2>/dev/null | sort -h | tail -20
0B /Users/txmmy/Library/Containers/com.docker.docker/Data/ethernet-vfkit.sock

105M /Users/txmmy/Library/Containers/com.docker.docker/Data/log
100G /Users/txmmy/Library/Containers/com.docker.docker/Data/vms
退出docker desktop，重新检查
du -sh ~/Library/Containers/com.docker.docker/Data/vms
确认下这是不是docker desktop的旧数据，因为我已经切换到orbstack
# 1. 确认当前 Docker 指向 OrbStack
sh-3.2# docker context ls
NAME DESCRIPTION DOCKER ENDPOINT ERROR
default * Current DOCKER_HOST based configuration unix:///var/run/docker.sock
如果当前是 orbstack，说明你现在 Docker CLI 用的是 OrbStack。
这个输出还不能证明你当前是 OrbStack，只说明 Docker CLI 走的是 /var/run/docker.sock。先确认 socket 背后是谁：
docker info --format '{{.OperatingSystem}} / {{.Name}}'
ls -l /var/run/docker.sock
如果 docker info 里看到 OrbStack，那 com.docker.docker/Data/vms 就是 Docker Desktop 旧数据，可以删
default * Current DOCKER_HOST based configuration unix:///var/run/docker.sock
sh-3.2# docker info --format '{{.OperatingSystem}} / {{.Name}}'
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
/
sh-3.2#
sh-3.2# ls -l /var/run/docker.sock
lrwxr-xr-x 1 root daemon 38 Jul 16 22:00 /var/run/docker.sock -> /Users/txmmy/.orbstack/run/docker.sock
sh-3.2#
可以确认，现在的 Docker CLI 现在指向 OrbStack：
然后退出 Docker Desktop，确保它没在运行：
osascript -e 'quit app "Docker"'
再删除 Docker Desktop 的 VM 数据：
rm -rf ~/Library/Containers/com.docker.docker/Data/vms
删除结束后检查
du -sh ~/Library/Containers/com.docker.docker 2>/dev/null
df -h /
