need a higher degree of isolation between processes for security or other
reasons, it is recommended to use full virtualization like
[QEMU](/docs/drivers/qemu.html).
## Docker For Mac Caveats
Docker For Mac runs docker inside a small VM and then allows access to parts of
the host filesystem into that VM. At present, nomad uses a syslog server bound to
a unix socket within a path that both the host and the VM can access to forward
log messages back to nomad. But at present, Docker For Mac does not work for
unix domain sockets (https://github.com/docker/for-mac/issues/483) in one of
these shared paths.
As a result, using nomad with the docker driver on OS X/macOS will work, but no
logs will be available to nomad. Users must use the native docker facilities to
examine the logs of any jobs running under docker.
In the future, we will resolve this issue, one way or another.
