The output on my Terminal app (i'm on Mac M1 Monterey, not Ventura cuz i hate it.) is the following:

`The shell appears to be executed non-interactively. If this is not the case,
please press CTRL-C and run the script under an interactive shell, for example
bash -i macos-guest-virtualbox.sh or zsh -i macos-guest-virtualbox.sh

Otherwise, the script will continue running non-interactively.

Push-button installer of macOS on VirtualBox

This script installs only open-source software and unmodified Apple binaries,
and requires about 50GB of available storage, of which 25GB are for temporary
installation files that may be deleted when the script is finished.

The script interacts with the virtual machine twice, please do not interact
with the virtual machine manually before the script is finished.

resuming the script by stages, and other topics can be viewed with the

Even if you got it working, the script supports Intel processors only.

[Pengupine]

Could i fork it to M1? Or help to add support to M1?

I believe VirtualBox x86 emulation is very slow on M1/M2/Apple Silicon processors. The process of creating a bootable install image should be tolerable enough (an overnight run) but I would not recommend trying to run the OS as a daily driver or even as a development environment.

At any rate the project is looking for maintainers so if you wish to maintain it you have to demonstrate a bit of proficiency and it's yours.
