Docker for Mac stopped running docker related commands

$ docker-machine start # start virtual machine for docker
$ docker-machine env  # it's helps to get environment variables
$ eval "$(docker-machine env default)" #set environment variables

If you run this command sequence, note that you’re running the VirtualBox Docker Toolbox VM setup, not the Docker for Mac beta any more. This probably comes with things like an older Docker daemon (the Docker for Mac beta package is now shipping with a beta release of Docker too). So, when docker says…

Error response from daemon: client is newer than server (client API version: 1.24, server API version: 1.23)

you just need to

export DOCKER_API_VERSION=1.23

I don’t know why the Docker client doesn’t automatically downgrade to an older protocol version; it’s clearly capable of speaking the older version and knows from the startup sequence what version the daemon wants.
