Error: unsupported macOS version

[TheKnarf]

I tried following the following instructions. Downloading the fedora-coreos-38.20230414.3.0-qemu.x86_64.qcow2 image (then converting it with qemu-img and crating an overlay). But I only get the following error:

unsupported macOS version

My arch is:

$ arch
i386

--bootloader efi,variable-store=efi-store,create

I believe the EFI bootloader only works from macOS 13. @cfergeau Am I right?

[praveenkumar]

Yes it is only supported or macOS 13 https://developer.apple.com/documentation/virtualization/vzefibootloader?language=objc and https://github.com/crc-org/vfkit/pull/18 where it is added in the codebase.

[gbraad]

You would have to specify the parameters yourself, as done in: https://github.com/crc-org/vfkit/blob/main/contrib/scripts/start-crc-bundle.sh or update to macOS 13.

Closing this issue as invalid. Error is as expected.
