Mojave Post-Install Issues

Hello fellow hackintoshers!

My Build Is:

GIGABYTE Z270X-SLI

NVIDIA GEFORCE GTX 770 (2GB)

INTEL CORE i7-6700

The two issues I am having are:

1) No internet. I am wanting to connect by ethernet. I was able to do so with a Catalina install. The reason I am downgrading to Mojave is because my audio interface is 32 bit, not 64 bit.

2) I cannot boot to Mojave via the hard drive, only the flash drive.

After googling my motherboard + hackintosh, it is my understanding that IntelMauseEthernet is the kext I need to get it working.

However, I do have this kext placed in my EFI folder. Perhaps it needs to be placed elsewhere?

And regarding booting via the hard drive, I did copy the EFI folder from the flash to drive to the Macintosh HD. However, it still does not boot from the hard drive. It gets stuck in clover...

I am thinking that perhaps I need to copy the EFI folder to the Macintosh HD - Data drive instead. I will try to do that now.

Cheers in advance ya'll!
