OpenCore 0.6.0 - Asus Prime Z270-P, i5-7400, 16GB HyperX 2666MHz, Dualboot, Samsung NVME

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


  • 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:

  1. I cannot reboot or shutdown from MacOS. It always goes to black, but its still on and nothing happens
  2. 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.
  3. 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!
