Thanks for the question! If you are using Docker for Mac, then you will need to access the docker virtual machine differently from the way described in this blog post. From this forum post I linked below, I found this command to enter the VM:
docker run -it --privileged --pid=host debian nsenter -t 1 -m -u -i sh
Once inside, then you can find the layers at the same locations as described in this blog post:
/var/lib/docker/aufs
Resources:
Hope that helps!
