问题:

I tried just 'docker-machine upgrade' and that did some work but I don't seem to have the latest CLI.

If I do 'docker version' I get:

Client:
 Version:      1.8.2
 API version:  1.20
 Go version:   go1.4.2
 Git commit:   0a8c2e3
 Built:        Thu Sep 10 19:10:10 UTC 2015
 OS/Arch:      darwin/amd64

Server:
 Version:      1.11.2
 API version:  1.23
 Go version:   go1.5.4
 Git commit:   b9f10c9
 Built:        2016-06-01T21:20:08.558909126+00:00
 OS/Arch:      linux/amd64

I understand there are some new commands I'm not seeing so I suspect I don't have the latest software.

Since you are on mac, you should install homebrew and from there you can install and upgrade docker with the command brew install docker and brew upgrade. Homebrew is a package manager for mac that makes installation of such applications easy.

Surprisingly, this GUI button helped me.

Just try this way:

$ mkdir ~/docker
$ curl -Lo  ~/docker/docker-1.13.0-dev https://master.dockerproject.org/darwin/amd64/docker-1.13.0-dev
$ sudo rm -f /usr/local/bin/docker
$ sudo ln -s ~/docker/docker-1.13.0-dev /usr/local/bin/docker

you can find all current master branch in this link
