Thank you! I&#x27;ll have to check this out. It baffles me that a company such as Docker has yet to make using its primary product on Mac OS X simple plug and play. Needing to remember to run `eval $(docker-machine env docker)` is not a sustainable solution. Hell I know about this and would occasionally forget and become confused at the error messages.<p>In fact I put this horrible hack into my ~&#x2F;.bash_profile (I wouldn&#x27;t recommend doing this but, hey, it works.):<p>docker-machine start dev<p>eval &quot;$(docker-machine env dev)&quot;
