> The model here is for /boot/efi to be an HFS+ partition rather than a FAT one.

1. 
Am I reading this correctly? Are you suggesting an hfs+ EFI System partition
rather than FAT32? Apple's own EFI System partition is FAT32. The UEFI spec
requires that it be FAT (FAT32 for all practical purposes). I understand that
this is not UEFI, but do you propose a 2nd EFI System partition that's hfs+? Or
reformatting the existing one?

2.
When referred to "secure boot" and Apple hardware, do you mean UEFI 2.3.1
secure boot? Or Intel TXT Trusted Boot? Or other? I ask because none of Apple's
hardware has UEFI 2.x compliant firmware, let alone 2.3.1.

3.
Question: Is there something in NVRAM that Apple's EFI depends on that
efibootmgr doesn't use? The Mac OS X 'nvram -p' produces more information than
efibootmgr. Attached is output from that command for a MacBookPro 8,2.

4.
On the EFI System partition I'm finding a 15MB file
/EFI/APPLE/EXTENSIONS/Firmware.scap on two computers. Apple MBP 4,1 (2008), MBP
8,2 (2011). Diff claims they are identical. The file is not present after
partitioning/formatting with Apple Disk Utility, or after installation of
either Mac OS 10.6.x or 10.7.x. It appears within a few minutes of the very
first login following Mac OS installation if the system has an internet
connection. Does anyone know what this file is?
