How to ?

Just to be clear, I didn't installed High Sierra, I'd like to but first I'd just like to have access to my computer :)
It was some kind of small uptade, to bug fixes and stuff ... (on the appstore)

My problem here : have access to my computer again and clean the mess that i did

Thanks for your time !

If you did not try to install High Sierra then the system definition is not the problem.
Boot with nv_disable=1 and then update the Nvidia web drivers.

Thanks I had acces to the computer with nv_disable=1 and -x !

So it was just me installing the 10.10.5 version of Yosemite ...

And when you say update the web drivers ... With CUDA in the settings ?

The web drivers are not the CUDA drivers although if you use them then you should update them too.
 
Thank you so much :D
 
Change your system definition to one that does qualify for High Sierra, suggest iMac14,2.
I succeed to do that. So i'm now able to download high sierra ...
What is the method to do this uptade from 10.10.5 to High Sierra ?

Backup.
Test your backup.

Change your system definition to one that qualifies for High Sierra (iMac14,2)
Test that everything is still working.

Update Clover and FakeSMC.kext.
Test.

If you have a SSD you should put apfs.efi in /EFI/CLOVER/drivers64UEFI

Download and run the update.
You must boot with nv_disable=1 until you have installed the operating system and the new web drivers.
