macOS-Simple-KVM provides tools to set up a quick macOS virtual machine in QEMU, accelerated by KVM. It requires a Linux system with qemu 3.1 or later, python3, pip and the KVM modules enabled; a Mac is not required. Installation media is downloaded by running jumpstart.sh, with Catalina as the default version and options for High Sierra, Mojave or Catalina, and basic.sh starts the machine.
