It may be useful to know whether your Mac has a 32-bit or 64-bit EFI. This can be done by running the following command from an OSX Terminal (can run from the installer or recovery partition):
ioreg -l -p IODeviceTree | grep firmware-abi
This should return something like the following:
| • For 32-bit EFI: | | | "firmware-abi" = <"EFI32"> |
| • For 64-bit EFI: | | | "firmware-abi" = <"EFI64"> |
