This is achieved by applying ISOLINUX program isohybrid from a recent
ISOLINYX version to the already produced ISO images. syslinux-4.05
should probably do.
It is a daring mix of MBR, Apple Partition Map, GPT, and El Torito.
It seems to be specific to i386 and amd54 architectures.
You need to provide a VFAT image for EFI, and a HFS+ image for Mac. 

I have meanwhile documented it on byte level in
  http://bazaar.launchpad.net/~libburnia-team/libisofs/scdbackup/view/head:/doc/boot_sectors.txt#L398
(paragraph "SYSLINUX isohybrid for UEFI and x86-Mac")

xorriso will hopefully be able to do this trick together with jigdo
production, if the MBR template file stems from a suitable ISOLINUX
version. (It has to reserve its first 32 bytes for a mock-up of an APM
Block0.)
Implementation has begun but will last a bit longer because the
backup GPT at the end of the image does not yet fit into the
architecture of libisofs.


Have a nice day :)
