Hello MaLd0n,
My configuration:
Gigabyte EP45-DS3 F9, Intel Core 2 Quad Q9300, 8 GB DDR2, SSD Kingston A400 240GB, NVIDIA GeForce GTX 670 2GB DDR5
I use your advice from PM and installed 10.13.6 High Sierra (17G6030). After few boots from usb stick with kernel panics I managed to reach installer screen. Today I bought a 240GB SSD and proceed to install. Finally I succeded. Everything seem to work. Network works, Sound works (thru bluetooth adapter because I use a bluetooth speaker and bluetooth headphones), Video works with Nvidia driver downloaded with nvidia-updater.sh. I don't know how to test 3D graphics if works.
What I noticed is after nvidia driver install, in "About This Mac" video card appear with 1024 MB. Before installing driver it showed 2048 MB
CPU details did not match also.
When I connect a flash drive to my USB hub connected to my display I receive the following message.
If I connect to the USB port from the back of my PC, the flash drive is mounted.
I attached SendMe file. Thanks!
