Bootable EFI CDs on Intel Macs
Bootable EFI CDs on an Intel Mac are a bit different than a normal EFI CD. As such, they need special support.
What's needed
- HFS+ support for blessing a file
- make dumpet correctly interpet and display hybrid iso/apm CDs and HFS+ blessing
- Ability to create image files for the icon and label to be used on the boot option screen
- Ability to create CD that has el torito images as well as an Apple Partition Map which specifies the HFS+ image as a partition.
- icon/label images included in *-logos
- modification of mk-images to create the appropriate HFS+ image and add it to CD images.

Alternate Approach
There's also another way:
- Put a GPT table on the CD
- Create an EFI System Partition that points at the El Torito image
- copy /usr/share/pixmaps/bootloader/fedora.icns to \.VolumeIcon.icns
- Put a label file at \{somefile}
- Make sure the bootloader looks at the iso9660 image instead of El Torito or the EFI System Partition.
