That's a good question, why I don't have it. I am trying to boot so I can check again but I must have messed up something in clover and hangs on the startup process... I will revert as soon as I login from a backup.
I used this thread https://www.tonymacx86.com/threads/update-directly-to-macos-high-sierra.232707/
Just to indicate how I managed to update if other have the same setup as mine and some issues : I went into the bios, found the iGUP and put it on disabled, saved and reboot, then I got an error from the installer telling me it couldn't find the right bundle. So reboot back into Sierra, then I deleted the installer, redownloaded it from the AppStore, relaunched the install process and all went well =)
Cheers Fumomono, that worked a treat! I can't thank you enough!Just to indicate how I managed to update if other have the same setup as mine and some issues : I went into the bios, found the iGUP and put it on disabled, saved and reboot, then I got an error from the installer telling me it couldn't find the right bundle.

Hi, not sure wether you fixed it, but in case: you shouldn't enable the iGPU, it's the multi-GPU setup that is creating an issue from my understanding. So basically try in your BIOS to disable both the iGPU and 1 card (I don't know if the SLI cable will be an issue or not) and see if you can install like that. Or disable both cards and go with the iGPU for the install (of course plug your display on the iGPU in this case). If your BIOS can do that, you should be fine. Otherwise you can go back to Rehabman post, there is a way to do it without BIOS intervention nor physical removal, but that's much more complicated than what I just indicated (requires specific injection technics).I tried to enable the IGPU in Bios and boot, but it won't even display clover GUI, it will just show a blinking cursor.
