The changes recommended by Thomas Schmitt not only made the iso image created by grub-mkrescue work for my Mid 2010 Macbook Pro, they also made it work on a Late 2009 iMac (irrelevant details see <https://bugs.gnu.org/35856>). It appears post-2010 Macs boot all grub-mkrescue iso images without issue.
