Docker.app will complain about incompatible processor, so we will use Docker Machine.
Download Docker for Mac (Docker.app). It contains some binaries that are necessary.
brew install virtualbox docker-machine
|* An implementation of C11 stdatomic.h directly borrowed from FreeBSD|
|* (original copyright follows), with minor modifications for|
|* portability to other systems. Works for recent Clang (that|
|* implement the feature c_atomic) and GCC 4.7+; includes|
|* compatibility for GCC below 4.7 but I wouldn't recommend it.|
|* Caveats and limitations:|
|* - Only the ``_Atomic parentheses'' notation is implemented, while|
|* the ``_Atomic space'' one is not.|
