first Hackintosh [ need help ]

Hi,

I wanted to create a Hackintosh very long time and now i had a time to play with it .

i created a macOS high Sierra (17G66 build) bootable using vanilla script and Unibeast .

​

afterwards i managed to find this github

https://github.com/saikatm/gigabyte-b360m-d3h-hackintosh-efi

[this is my motherboard]

​

which helped me to do all the installation but

the MAIN issue is graphics,

my graphic card is Nvidia GeForce 750 Ti [i can upgrade if needed]

and i can't manage to install it. i've tried many methods even the script which downloads and installs the WebDriver. but still it's not running

​

please help :)

THANKS ALOT!
