Docker for Mac currently uses HyperKit (reference: https://docs.docker.com/docker-for-mac/docker-toolbox/)
Docker Desktop uses HyperKit instead of Virtual Box. Hyperkit is a lightweight macOS virtualization solution built on top of Hypervisor.framework in macOS 10.10 Yosemite and higher.
Is it possible to run a traditional Debian/Ubuntu VM using HyperKit on a macOS 10.15.5 or newer?
