A friend’s “early 2014” MacBookAir6,2 does not have issues with the
old iso image. It seems likely that only old Macbooks are affected.

I see both “GRUB 2.02” and “EFI Boot” when I zero it (I have not tried
on Guix 0.16.0 this time though).
So the options are:
· Update mtools and then somehow patch mformat to zero out this
region.
· Patch grub-mkrescue instead to make it use mformat -k. Vladimir
Serbinenko on the grub-devel list said this removes only information
that is “Probably” not useful anyway, see
https://lists.gnu.org/archive/html/grub-devel/2019-04/msg00100.html
· Ignore the issue. The only affected machines we know are old Macbooks.
