OC DELL Latitude E6420

  • Okay i think i will try this evening.
    keep us informed if everything still work :)


    good luck to you

  • Hi,

    Thank you for the EFI files !

    I am stuck to boot on the usb...

    I have installed the EFI folder onto the usb directly (and not on the hard drive where MacOS is already installed), but i can’t boot on the usb...


    And when i try to add the boot argument in the BIOS, i’m not able to find the bootx64.efi...

    This evening i will try as you said : directly install the EFI on a partition of the hard drive

  • I thought it was possible to take the boot file directly from the usb (i didn’t use the efi partition, but i did a partition on the stick), but i didn’t think it would stuck...

    Thanks for your tips ;)

  • Anyhting is done, but it would be very cool if i manage to :)

  • Basti Wolf i use a 2011 Dell Latitude e6520. It needs a patch of Big Sur, which is provided in this case by the OC EFI folder of Mo-6420


    In fact both of the e6520 and the e6420 are close in hardware, so it is possible that it works :)
