Hi! I have your instructions below and have also built a Hacki! I'm not a big pro in the Hackintoch area, but it has almost "out of box" with their EFI folder for AMD worked out.
Asus STRIX370-G only without Wi fi Latest BIOS 0606
32 GB Corsair Vengeance DDR4 2400
Same PCI-e SSD
Still 2 TB crusial 400 SATA SSD
Still 512 Intenso SATA SSD as backup for carbon copy
Sapphire Pulse RX 580 8 gig
Dell 27-Inch 4K via DisplayPort monitor.
ViewSonic 27 inches Full-HD via DVI monitor. Everything works fine, just gave a few kext to it. Display Port audio also goes, slip and wake, turn off, iMessage. Adobe CC 2018 full package and Final Ccut latest version works flawlessly with full hardware acceleration, open CL and Apple Metal. I also have Sierra over AppStore to latest version updated-Flawless.
Do not have a BT-WiFi card, but it comes.
have also tried their USB AML. and DSL. Use files, but unsuccessful, all USB ports work as before, nothing has been turned off. Aml. and DSL. Files have been copied to folder “patched”. Did something wrong? Later also post EFI folder. How can I make a donation to you as thank? Sorry for my BAD English
