I pulled the image on the Docker for Mac, but the /var/lib/docker directory is missing.

I am using Docker for Mac. I don't know where to store the image file.

 docker run hello-world

I did. Of course, I don't have a hell0-world image file on hand, so it was pulled.

Unable to find image' hello-world:latest'locally
latest —Pulling from library/hello-world

I checked and found that the image file was stored in /var/lib/docker on various sites, but the docker directory does not exist under /var/lib. Could you tell me where it is?

By the way

 docker info

If you try , you will see the following output:

Inside

Root Dir:/var/lib/docker/aufs

It says , but you cannot access this directory. Or rather, there is no directory called docker. Please let me know if you understand.

macos docker

The Docker image file is not stored directly on the macOS file system.

Under User Home Directory:

~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux

contains an image of a virtual machine (Linux) called Docker.qcow2.

The image file is stored on the machine's file system.

Therefore, /var/lib/docker/aufs is the path within that virtual machine.
