You are correct. As explained in the article, containers are running on a Linux VM, from Mac OS X, not natively on Mac OS X.
A few differences between Hyper for Mac and boot2docker though:
1- Docker commands are run inside the boot2docker VM and not directly on the host
. Hyper daemon directly runs on your Mac.
2- When using boot2docker, each time you restart the VM, you have to manually mount the drives (and reinstall Fig if you're using it)
3- While boot2docker is a "wrapper" around Docker and VirtualBox, Hyper for Mac is part of the whole Hyper ecosystem, providing a similar environment on Linux, or Mac OS X.
