Dear Sir, I installed High Sierra 10.13.6 onto my system today after following your tutorials to the core but stuck with some errors. First is that I cannot Erase or Partition my 2 TB Seagate HDD during High Sierra installation - I installed High Sierra 10.13.6 on one of my SSD. Second, shutdown is taking a bit more time than is normally taken. Although I have not installed the Nvidia drivers today, want to know any process involved for that. Audio is perfectly working, no issues there. In the "About my Mac" section, my CPU is shown as "Unknown" and also the Mac model is not correctly displayed. Hope you will help me out of this situation. I have attached a screenshot of my system and also included my DSDT files. My system specs for your reference are :-
1) Gigabyte Z370-HD3P Motherboard
2) Intel Core i5 8600K Processor
3) Gigabyte 1050 Ti OC Edition 4 GB Graphics Card
4) 2 x 2 TB HDDs (Windows 10 and Mac separately)
5) 2 x 240 GB SSDs (Windows 10 and Mac system separately)
6) 32 GB Gskill Ripjaws V 2666 Mhz RAM
7) Cooler Master Hyper H410R CPU Cooler
8) Cooler Master CM 590 iii cabinet
9) Antec 750 W PSU
