Please try the following:

• Replace OsxAptioFix2Drv-free2000.efi with both of the following:
  • OcQuirks-4.efi
  • FwRuntimeServices.efi
• These are available from here. Just copy them into the same CLOVER/drivers64UEFI folder and remove OsxAptioFix2Drv-free2000.efi.
• If this alone does not help with repeated reboots, perform a CMOS Reset by shorting the two designated pins on motherboard with a flathead screwdriver.
  • This will reset BIOS parameters to factory defaults, so configure all BIOS parameters again. Be sure to start with Save & Exit --> Load Optimized Defaults.

Ok, I replaced OsxAptioFix2Drv-free2000.efi with

• OcQuirks-4.efi
• FwRuntimeServices.efi

I Rebooted the hack without problem. I need some day testing before being sure that the problem is solved

Hi CaseySJ does Netflix and Apple TV + on MacOS Catalina work for you?

@svandive thanks, I have version 3.23.66 (its posted on their website). I should have been more specific. I was hoping it would work with the Lighting Node Pro. I checked corsair forums and it doesn't seem it will at this point.

You can run a windows VM in macOS, and it will recognize the lighting node pro and you can control it. I haven't been able to get it to control the Mobo or ram though

I can confirm that the new LG UltraFine Display 5K (27MD5KL) works flawlessly on Thunderbolt 3 under macOS Catalina 10.15.2 with a Radeon VII DisplayPort output plugged in the Designare input with a full 5K stream* :

~ % system_profiler SPDisplaysDataType | awk '/Resolution/{print $2, $3, $4}'
5120 x 2880

I use an iMacPro1,1 SMBIOS with iGPU disabled in the BIOS, no DRM issue with Netflix on Safari or the TV app. Integrated speakers, Webcam and the three USB-C ports on the back works as well.

It also works on Windows 10 (dual-boot) but seems to be limited to 4K (which is more than enough for gaming as far as I'm concerned).

*Edit : after checking AGDCDiagnose logs, its seems to be downscaled from 5120x2880 to 3840x2160 before being sent to the monitor. Hard to see with the naked eye.

Hello @kronxito

Apple TV+ works perfectly. Because I'm not a Netflix subscriber, I have not personally tested it. It may work better in Chrome or Firefox than in Safari.

macOS does not necessarily report the correct output resolution! But there is a standard utility called adgcdiagnose that we can use, as follows:

• Run Terminal and type:
  /System/Library/Extensions/AppleGraphicsControl.kext/Contents/MacOS/AGDCDiagnose -a > ~/Documents/AGDCDiagnose.txt 2>&1
• This will create a file called AGDCDiagnose.txt in your Documents folder.
• Please upload this file. It will contain intense amounts of low-level detail that we can use to determine the real output resolution.

With one DP-In connection, it is very likely that macOS is sending a 4096x2304 signal to the LG. The LG is then scaling it up to its native 5K resolution. Also see this post:

sorry the file is now attached the one drive connected to the SATA PCIe card are working fine.

Yeo that works but you it didn't hold the config after closing the VM. Oh well...hopefully corsair will add soon to the macOS app

I've seen the post but it was referring to the old LG UltraFine 5K, I thought the new one might support DP 1.3+ / HBR3 which would allow true 5K on a single 4-lanes connection.

But anyway the log file confirms there's only one DP 1.2 HBR2 (4x5,4Gbps) connection, so true 5K is not possible :

Connections:
  1:
  2:
* 3: [DP 1.2 4 x HBR2]      Status: [4 x HBR2 7777]      caps [features 0x101001b, p_encoding 0xd]             Sink   OUI:204-045-140 27MD5K [050-055-077-068-053-075] HW Version: 48   FW Version: 3.4

Further down the lines I can see what seems to be a downscaling from 5120x2880 to 3840x2160 :

Refresh Rate (Calculated)    60 Hz
Refresh Rate (Stored)    0.0 Hz        Refresh Rate (Stored)    0.0 Hz
Window (Active)    3840 x 2160        Window (Active)    3840 x 2160
Window (Scaled)    5120 x 2880        Window (Scaled)    5120 x 2880
Scaled Inset    0 x 0        Scaled Inset    0 x 0

The same test with my MacBookPro13,2 reveals two DP 1.2 HBR2 connections (the only difference being features at 0x1000a instead of 0x101001b and p_encoding at 0x0 instead of 0xd).

Critical Question!
I just bought 2x Fenvi T919 for my 2 hackintoshes which run by Z390 Designares (https://www.amazon.co.uk/gp/product/B07VCCZS54/?tag=tonymacx86-21). The main purpose of my purchase is that I'm already tired with 3rd party keyboards and mice (already tested a few of Microsoft and also Logitech). I also I want full support experience with my iPhone 11. That means Handoff, Airdrop and ofc Sidecar support with iPad 2019. As of keyboard and mouse ofc, I'm willing to get soon Magic Mouse and Magic Keybaord. So, the Critical question is: am I gonna get full support without issues with Apple mouse and keyboard and also native experience with iPhone 11 and iPad 2019? Happy NEW Year to everyone and I wish you all Good Health for you and your families!
