I just installed Kitematic, a Docker front end for OS X. A very good looking GUI for running Docker apps on your Mac.
It's only at version 0.1 but installed fine and I was able to set it up in ten minutes or so. In the background it'll install boot2docker for you. Then act as a GUI frontend for all your Docker needs.
I'l definitely give it a try the next time I need to run Docker on my Mac.
