1.) During boot press F8 during the BIOS splash screen
2.) In the BIOS boot menu select the USB Stick to boot with
3.) In the Clover boot menu select the MacOS Installer on your USB Stick
4.) After successful system boot complete all tasks for initial macOS Installation on your system disk. After installing a macOS Installer partition on your system disk, the system will reboot..
5.) During reboot press F8 during the BIOS splash screen
6.) In the BIOS boot menu select the USB Stick to boot with
7.) In the Clover boot menu select "Install MacOS.." partition on your system disk
8.) After the second part of the macOS installation with the progress bar at 17 min remaining the system will reboot one more time
9.) During reboot press F8 during the BIOS splash screen
10.) In the BIOS boot menu select the USB Stick to boot with
11) In the Clover boot menu select the "MacOS High Sierra" partition on your system disk
12.) After successful system boot and after completion of the last step of the macOS installation procedure you have to sign in to iCloud.
13.) You are done.

I basically just rewrote a complete part of my guide.. :rolleyes:

After the step 6, Clover show me two entries : 1/ USB Stick and 2/ "Boot macOS Install from OSX", who OSX is the target drive I've formated before, so I have to select the second one ?

Yes, so we are agree since the beginning. :)
This is what I got at the step 6 :

But I don't understand why it can't boot the second time.

Neither do I and I also do not know how to help further. Are you also applying step 5? Please revise once more your ENTIRE BIOS settings and try to loose your remaining knot by yourself. I am sure with same patience and some trial error you will manage finally. Something seems still wrong in your system configuration at some place.

Good luck,

Attached below a revised version of your EFI-Folder originally attached to post #2577.

I basically removed all unnecessary kernel patches, not only by also assuming that your MSR register is unlocked.

If this EFI-Folder does not reveal the expected performance, there is still something at odd with your microcodes.

BTW.. the 10.13.6 XCPM_performance_patch is not supposed to work with 10.13.6 SU.

With this, the topic is also closed from my side.

Cheers,

Just wanted to give you an update. If I disable the performance patch, enable the KernelPM and xcpm_core_scope_msrs with your posted efi, my cpu performance is outstanding!!!! Ill update this post with Intel Power Gadget shortly. Seems Geekbench is website is giving 500 error code atm for submitting results. But results in Cinebench are good.

Which means that your MSR is locked..
