Mac OS is not even using the (protected) EFI boot partition (take a  
look at it yourself - it's empty), keeping all the EFI stuff on the  
(quite a bit harder to find) Mac OS boot partition (which isusing yet  
another FS instead of a FAT 32 FS to make things worse). And the MBR  
"partitioning" is just a protection against any OS that might not  
understand GPT partitions and threaten to abuse the medium. It is  
meant to contain _one_ partition occupying the entire disk.
