<< Solved >> HP 4300 pro High Sierra

[madvinegar]

Hello guys. I would like to have your guidance and advise on the following.
I recently purchased from ebay an HP 4300 pro sff.
I have made some upgrades to it, and more specifically:

Changed the Cpu to i5-3570K (HD 4000)
Upgraded the ram to 8gb
Installed an Nvidia 1050ti Low Profile
Installed an SSD (together with the HDD)

My intention is to try to install High Sierra, as this is the latest macos that supports nvidia web drivers, correct?

I have been trying to install it but I always get into errors like "error loading kernel cache 0xe" or "0x9" etc. And the system just reboots.
I have tried multiple solutions without success up to now.
Has anyone else made a successful build with the 4300 pro? If yes, is there an EFI folder I can use to copy/paste in the bootable usb stick?

Fyi, I have access to macos system. I own a macbook air, and I have also successfully installed mojave to an HP 8300 elite tower.

Any help will be very much appreciated.
Thank you.

So, after some attempts I have managed to successfully install High Sierra and update it to 10.13.6. I have also installed l the appropriate Nvidia Web drivers.
The only problem I have is that in order to be able to get into the desktop I can only do it if in clover I select "Nvidia web drivers" and "single user mode".

Can anyone help? Thanx

Managed to find the solution. I had to update all the kexts with the latest ones.
