Here is a short description about how GRUB/i386-pc works:

1. At the initialization stage, GRUB reserves about 2/3 of the whole 
memory for OS images. This starts from 1MB. GRUB never use this region 
for its own use.

2. When GRUB boots an OS image actually, GRUB releases all memory 
regions which have been allocated for its own use.

3. GRUB copies OS images to appropriate locations, according to 
Multiboot Header or other information. This stage is performed by the 
kernel (more precisely, the assembly code located at the region 
starting from 0x8000).

I think you can use the same way on Mac as well.
