[Qemu-devel] [Bug 1776920] Re: qemu-img convert on Mac OSX creates corrupt images

[John Snow]

I haven't had the time to look just yet.

If there's a developer out there with a Mac has the bandwidth to take a
look at this I'd be grateful. (I don't have access to one presently.)

I see that the target filesystem is APFS however -- I think we might
have a bug in our APFS support. Do you have the ability to try it on
your Mac but on a non-APFS destination?

It looks like the image is pretty small (~6MB?) so maybe you can try
with a non-APFS formatted thumb drive?

My hunch is that:
- APFS source to FAT32 destination might work correctly.
- FAT32 source to FAT32 destination will definitely work correctly.
