On the MacOS machine, download the Mojave installer.

Virtualbox installs generally prefer to use an ISO file, which unfortunately will require some handiwork to get a hold of. This also includes Windows Subsystem for Linux, which tripped me up from installing. I use Linux in my screenshots as I use Docker on Windows. MacOS is also not installable on Hyper-V. ⚠️ At the time of writing, Virtualbox and Hyper-V cannot co-exist on Windows.

40GB of free disk space (more preferred).

At least 4GB of RAM (8GB or more recommended).
