How can I access BIOS/EFI in MBP Retina

How can I access EFI (or BIOS equivalent) in Macbook Pro Retina?


I tried to access with Option + Command + O and F. But, it doesn't work.


Is there anyone who saw the bios settings of MBP Retina?

MacBook Pro with Retina display, Windows 7

Try 0 zero instead of letter O Mate

if I did not overlook your questions this should do.


Cheers!

Apple disables the standard mechanism for entry into the EFI shell in its computers, but not the EFI shell itself. If you want to launch the EFI shell, you can download third-party software that changes the interface EFI shows you at start-up. This will void your warranty & support, so you'll have to use Google for instructions.
