Error with pre-create check using --driver xhyve on macOS

I’m running a brew-installed docker on macOS High Sierra (latest). When trying to create a machine using

docker-machine create --driver xhyve

I get

Running pre-create checks...
Error with pre-create check: "Virtual Box version 4 or lower will cause a kernel panicif xhyve tries to run. You are running version: 6.0.0r127566\n\n\t Please upgrade to version 5 at https://www.virtualbox.org/wiki/Downloads"

Who is responsible for this (erroneous) check? xhyve or docker-machine? And what can I do about it?
