Finally got the newest Catalina working after using the OC vanilla desktop guide a few times. I first got it running using a standard EFI from a Technolli guide, but it seemed to be old and I got a lot of errors during boot. Now everything seems fine during boot. I first used the standard SSDTs, but changed them after getting windows to boot with some SSDTTime generated. I did not notice any change in boot time after the change.
Guide I used: OpenCore Desktop Guide
Hardware:
- CPU: Intel i5-7400k (Kaby Lake)
- GPU: 2x Sapphire Nitro+ RX 570 4GB cards
- RAM: HyperX Fury 16GB DDR4 2666MHz
- Motherboard: Asus Prime Z270-P
- Wifi/BT Card: None yet (ordered off Aliexpress)
- SMBIOS: iMac17,3
- Storage NVMe: Samsung 970 EVO Plus NVMe M.2 500GB for Windows 10 Pro + Intel Pro 6000p NVMe M.2 256GB for MacOS Catalina
- Storage SATA SSD: 2x Samsung SSD 860 EVO 500GB (one storage disk for each OS)
- Storage SATA HDD: 2x 4TB Seagate (not sure what ill use it for yet)
- Case: Corsair Carbide Air 540
- CPU cooling: Corsair Hyrdo H100i V2 Water-cooling
What's working:
- Audio (ALC1150)
- Ethernet
- Wifi and Bluetooth on both Mac and Windows with USB bluetooth adapters
- dGPU
- USB 2.0 + USB 3.0
What's not working:
- Sleep/Wake | Reboot/Shut Down
- iGPU Intel Graphics 630 - Not sure why that's not working.
What I haven't tested:
- Filevault
- Sidecar ( not sure I'll bother to try, not using)
There is basically three thing bothering me after install. Here they are ranked:
- I cannot reboot or shutdown from MacOS. It always goes to black, but its still on and nothing happens
- Just after booting there is a noticeable, lag/hang on the mouse, that seems to disappear after a few minutes. Not a huge problem, but wasn't there with the Technolli install.
- IGPU is not working it seems, or at least it does not show in MacOS
If anyone can point me in the right direction for these problems, I would be eternally grateful!
