Problems making bootable usb

I have a macbook air and an old EOL chromebook, KEFKA Intel Braswell. I ran Install/Update UEFI (Full ROM) Firmware from mrchromebox without a problem Firmware Utility Script | MrChromebox.tech and that part is ready.

I’m attempting to put Fedora Kinoite 40 on the chromebook. To make the bootable USB:
Flashing using Ventoy (Windows/Linux/macOS) (Making a Bootable USB | Chrultrabook Docs)

But hunting around it seems I cannot do this on a mac? If I’m wrong, please advise how to run it. I’ve tried this as noted in the docs

sudo ./VentoyGUI.x86_64

and after further googling:

./Ventoy2Disk.sh

The first does not work (cannot execute binary file), the second is apparently incompatible and returns: xzcat: command not found.

Also attempted the fedora media writer but I think I don’t know enough of the process to get it to work. Fedora Kinoite | The Fedora Project

I have worked with Linux & Unix but it was decades ago. Thanks!

The instructions in the documentation is specific to using ventoy via chromeos, since it can be a little weird

I do not believe ventoy supports macos: Download . Ventoy

Itd be better to just use dd in your case anyways: linux - How to copy an ISO image onto USB with dd - Super User

Thank you I’ll try it!
