In 2011 the Macs had Intel x86 CPUs. The PowerPC Mac era ended in 2006 https://en.wikipedia.org/wiki/Power_Macintosh > I'm not sure about your technical problems.

But indeed some x86 Macs seemed to need a HFS or HFS+ filesystem which had to be announced by an Apple Partition Map entry. One can see such a partition table in Debian amd64 ISOs where it marks the EFI partition with its FAT filesystem. It stems from Matthew Garret's work to get a bootable Fedora ISO for EFI and x86 Macs. https://mjg59.dreamwidth.org/11285.html But Debian never had a HFS+ filesystem image in its ISOs for which the APM would make sense. grub-mkrescue for x86 EFI still creates a HFS+ filesystem and marks it by an Apple Partition Map entry. But even GRUB's then developer Vladimir Serbinenko could not tell which x86 Mac generation needed HFS+ for booting, when he submitted the HFS+ code for libisofs/xorriso. That was in 2012. So i assume that a 2011 Mac boots via EFI, not via HFS or HFS+. Have a nice day :) Thomas
