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

[Waldemar Kozaczuk]

I have done more tests based on your suggestion and I think it is the
opposite. The problem happens is the source is APFS.

Following failed:
APFS -> ExFAT
APFS -> Fat32

Following worked:
ExFAT -> APFS
FAT32 -> APFS

So for now my workaround is to use USB stick formatted with FAT32 or
ExFAT, copy the source images there and then convert to somewhere or my
main drive with APFS.

My regards,
Waldek
