<< Solved >> Problem installing High Sierra on GA-X79-UP4

[cafenoir]

Hi all,

i've got some troubles with installing High Sierra on my old GA-X79-UP4
After a lot of trial and errors, i finally reached the installer (which is incredibly slow btw). But after restarting and maintaining the installation i got prompt that HS can't be installed on my computer.

I'm a bit of a 'newbie', I installed with succes Sierra a few years ago, and after that i didn't that much with hackintoshes
So hopefully somebody can help me out!

My setup:

MoBo: Gigabyte GA-X79-UP4
CPU: Intel Xeon E5-1650 v2
Graphics: EVGA Geforce GTX760 Superclocked ACX
HDD: Samsung 250GB 840 Evo
Power: Corsair RM 650i

I attached my EFI.

Big thanks in advance!

Hi Sjchen,

thank you for your respons and the files!
I gave it a try, but unfortunately i can't reach the installer, because there seems to be no output to the screen. My screen says: 'no signal'. Computer is still running and not restarting, but just no output.

Attached a screenshot just before losing the signal.

Do you have any ideas to fix this?

Oh... add this line in Boot Aguments
nv_disable=1

Ah, stupid me! I thought I already did that.
But it's seems to be working! Great, thank you very much!
Only USB3.0 isn't working yet, but I'm working on that

The second message about VoodooTSCSync configurator, is that message meant for me?

Thanks again!

Yeah, you'd better to modify that kext for your CPU.

No need if you use RehabMan's fork.
