So the ISO only =E2=80=9Cfails=E2=80=9D (somehow?) on old Macs, is that cor=
rect?

If it=E2=80=99s =E2=80=9Cjust=E2=80=9D about old Macs, that=E2=80=99s not a=
 1.0 blocker for me (though
it=E2=80=99s something we should fix.)

If the issue might be broader, we need more data to estimate the scope
of the problem (your table mentioned UEFI vs. =E2=80=9Clegacy=E2=80=9D boot=
 and Lenovo
laptops, which I=E2=80=99m not sure how to interpret.)

Thanks,
Ludo=E2=80=99.
