[MAC HELP] Does Mac has a grubx64.efi ?

[Amit kumar]

Hi ,

I am trying to boot a mac OS X from the efi shell so i opened the EFI partition.
As usual there was EFI directory inside which there was APPLE director.
so i went to EFI/APPLE director and found out there where two more directories inside /EFI/APPLE
1. FIRMWARE and 2. EXTENSIONS but there was no grubx64.efi like linux system.
E.g 
we can boot ubutu using :
EFI/ubuntu/grubx64.efi 
and for windows we have
EFI/Boot/BOOTX64.efi 

i found out there is a ThorUtil.efi in /EFI/APPLE/FIRMWARE  but when i try to run it, it says ThorUtil.efi is not recognized as an internal or external command, operable program, or a batch file. 


Can some help me booting a mac OS from UEFI shell.
P.S :: I have a mac air 13, intel i5, OS X

Thanks And Regards
Amit Kumar

No, Apple probably does not ship a GPL-licensed GRUB loader.

You might want to look into Cloverboot and Hackintosh community solutions.

I presume you've read RodsBooks.com.
http://www.rodsbooks.com/linux-uefi/
http://rodsbooks.com/ubuntu-efi/index.html

You might try looking into using rEFInd instead of GRUB.

I don't think Apple provides a UEFI shell compiled for their systems.
I'd love to see a support article that shows how to do that!

Is there and end-user support forum for Apple EFI issues for end-users?
Especially now that Apple has eficheck.

The boot-dev list seems close, but is abandoned and for developers only.
https://lists.apple.com/mailman/listinfo
https://lists.apple.com/mailman/listinfo/boot-dev
https://lists.apple.com/

It seems the best choice is to do a general post on the Discussions site?
https://discussions.apple.com/
https://discussions.apple.com/search.jspa?q=EFI

You might try the GRUB support list:
https://lists.gnu.org/mailman/listinfo/help-grub
https://savannah.gnu.org/mail/?group=grub
https://www.gnu.org/software/grub/grub-mailinglist.html

Another option may be StackExchange.

The common location is System/Library/CoreServices/boot.efi on your OS boot volume.
