Thank for your fast answer.

I removed alternatively OsxAptioFixDrv-64.efi first time and after removing OsxAptioFixDrv2-64.efi with the same error.

Just to let you known i set Bios Using Grafic UMA only

secure boot disable

fast boot disable

What do you mean for (Intel HD5500 & Nvidia 840M disabled) is there something i have to do before installing?

Hi,  i follow all the instruction AHCI and UEFI were Enabled, Alway same error, i also tried to boot without Cache, Without Kext, Without Cache and Kext, In Safe Mode and tried all the other option.I don't have possibilities now.

Everything seem ok in the Bios i also tried many option.

I also boot Osx insane mode, attached the screen error message "Couldn't allocate device tree"

Atteched some images of Bios setting.

I don't known if have done the correct procedure.

I launch Clover V2.3K:r3330.pkg choose custom

change install location  selecting the install usb drive i have create

click customize and select only OsxLowMemFixDrv-64

The installer created a folder named EFI in the osx  usb drive visible partition partition i copy only the file OsxLowMemFixDrv-64 in the Efi normally invisible partition.

Is this correct?

In this way no good news.

Patience please i'm a musician,always use a mac…. not an engineer

I use  both efi boot and esp as your image

Today i tried every possibilities i also create a separate drive usb  clover boot formatted in  Fat 32 and nothing.

I also download another version of OSX 10.11.0 mine was 10.11.2 and nothing. I also delete the folders 10.6 10.7  10.10 and 10.11 levying only other were i copied the Kext included in your boot loader.

Can you attach  the efi folder so i can copy in my Efi partition? Of course i follow all the instruction included in Bootloader specific for Lenovo Z 70 80.

Tomorrow i will outside coming back friday stake all the time to think what can be the problem.

I'll try to attach all my Efi folder.
