Toolbox installs everything you need to get Docker running in development: the Docker client, Compose (Mac only), Kitematic, Machine, and VirtualBox. Toolbox uses Machine and VirtualBox to create an Engine in a VM to run your containers. On top of that VM, you can then use the Docker client, Compose and Kitematic to run containers. Docker for Mac vs. Docker Toolbox Estimated reading time: 8 minutes If you already have an installation of Docker Toolbox, read these topics first to learn how Docker for Mac and Docker Toolbox differ, and how they can coexist.
Docker-for-Mac sets up a small virtual machine via hyperkit, which is a xhyve-based virtualization solution. The quickstart terminal also sets up a small virtual machine, but it uses the docker-machine tool to create a virtualbox VM. Both of these approaches are valid approaches to get a running Docker-in-a-vm-on-your-mac, but they are different VMs.
Similarly, if I have a regular linux machine at my desk, and I pull an image, you won't see that image in the docker daemon on the linux machine at your desk. Both tools can coexist, but they don't share data.
Apple Mac Pro (Early 2009 - Firmware upgraded from 4.1 to 5.1) macOS 10.12.6 Sierra Docker Toolbox Docker version 17.07.0-ce, build 8784753 (from docker -version) Docker Kitematic 0.17.0 Hello, I have just downloaded and installed Docker Toolbox on my ancient half-timbered steam-powered Apple Mac Pro (Early 2009) (it does have 32Gb of RAM though!). I managed to download and run the Hello-World-Nginx image, so that’s good.

Flushed with my success with that, I then tried to download and run the MongoDB image. I’m probably being impatient and missing a step or two but if I try to do anything from the command line (iTerm2) I get the message Cannot connect to the Docker daemon at unix:///var/run/docker.sock.

Is the docker daemon running? What am I missing? Thanks Edit: When I say I succeeded in running the hello-world-nginx image, I meant that I was able to get it to run within the Kitematic utility. I couldn’t get it to run from the command line for the same reasons as mentioned above.
Carlcaulkett: if I try to do anything from the command line (iTerm2) I get the message Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? Run eval $(docker-machine env) You’ll need to do it in each running terminal. (I think in principle “Toolbox” comes with its own terminal environment that preconfigured this, but I never used it.) In theory the information this returns can change, but it’s always felt very consistent to me. Your VM’s IP address is probably 192.168.99.100, for instance.
If you don’t mind a complaint when your shell starts up if the VM isn’t running it’s safe to put this command in your shell dotfiles, or even to see what environment variables that command sets and hard-code those.
