macos-guest-virtualbox.sh is a Bash script that creates a macOS virtual machine guest on VirtualBox with unmodified macOS installation files downloaded directly from Apple servers.
A default install only requires the user to sit patiently and, less than ten times, press enter when prompted by the script, without interacting with the virtual machine.
Tested on bash and zsh on Cygwin. Works on macOS, CentOS 7, and Windows on x86 CPUs with VT-x or AMD-V. Should work on most modern Linux distros.
macOS Catalina (10.15), Mojave (10.14), and High Sierra (10.13) currently supported.
