It does some weird formatting to the usb stick. You literally have to use their tool to unformat it again otherwise it’s screwed. That’s been my experience.
I had an issue on my MacBook bios safety installing Fedora. Wouldn’t boot and even if I tried installing Ubuntu over it, still would not boot.
Had to reinstall Mac OS and have it repair the bios. Only after that could I get Linux installed and booting again.
I don’t know how they screwed it up but they did.
I’m not sure what you mean by broken bios. If you has broken bios, you wouldn’t be able to reinstall Mac OS.
Also any formatting tool in any OS should be able to turn bootable USB stick back to storage only USB stick. Windows, Linux, Mac, Haiku, *BSD, original Unix. Anything.
Mac OS doesn’t install like a traditional OS. It downloads an iso from the cloud, stores it locally and then installs itself. It lets you open a terminal and I put in some commands to clear and restore the bios before installing the OS.
Normally any formatting tool should work on the USB but Fedora does something to the USB that prevents that. It definitely ruined a usb 3 drive I had and no amount of formatting would get it to work properly until I used their Fedora usb tool.
They are doing something weird.
