Overview​

I used this guide as my starting point along with the more general guides found on other forums to arrive at this set of instructions. My goal was to transition from an older Mac Pro 6,1 where I had already installed my Sabrent Rocket NVMe (SB-RKTQ-2TB) and was using the 5600XT in an eGPU case (via Kryptonite and an Apple TB2-3 adapter) to something a bit more modern. Because the Mac Pro's NVMe was formatted GUID already, the process was creating this EFI and testing it on an external drive (USB3) and then once I arrived at something that worked, copying the EFI to the NVMe and moving it into its new home.

At the time of this writing, I'm using Big Sur 11.5.1 and OpenCore 0.7.1. To get this far, I had to first get Big Sur 11.2.3 working so I could setup a port map, then use that port map to survive the upgrade to 11.5.1.

The build:
  • NZXT 210 ITX case
  • NZXT X53 Kraken AIO cooler
  • NZXT C750 Watt PSU (ATX)
  • MSI Z590i UNIFY ITX motherboard (BIOS version 7D05v12)
  • Intel 10700K processor
  • 32 GB Corsair Ballistic RGB DDR4 3600 (BL2K16G36C16U4BL)
  • 2 TB Sabrent Rocket Q NVMe (SB-RKTQ-2TB)
  • Sapphire Pulse 5600XT
  • Broadcom BCM94360NG WiFi+BT
  • Dell S2331QS via HDMI
I'm using MonitorControl so that the volume controls for macOS also control the speakers on the monitor (and I can adjust the brightness of the monitor too via my keyboard).

You'll note I replaced the onboard WiFi with the usual Broadcom unit. The original guide didn't include instructions for how to get the included adapter working (no linked kexts, etc.) so I fought with this for a day or two and then spent the $49 to wash my hands of it. The card is not as feature-rich, but it does work out-of-the-box even during installer, which cannot be said of the onboard Ethernet (more on that later).

Installation of the card is simple but you will need to have the motherboard in-hand. You can loosen the 4 screws underneath that hold the whole heatsink apparatus together (you are not removing it, you just need to wiggle it in a moment). You then remove the 4 small screws securing the back plate (so you can remove it and get access to the card). You then have 2 more small screws holding the E-key'd adapter into its socket. Once those screws are out, popping out the original adapter is trivial and having a little wiggle room with the surrounding heatsink is enough to get it free. Replacing the card inside the carrier is trivial (2 screws and carefully disconnecting/re-attaching the antennas to the new one). Installation is the reverse of removal, as they say. The two screws that held the PCIe E-key adapter in place are also used to help draw the card back into the slot. From there, just run through snugging everything down.

I apologize for not taking photos of this process; the screws to deal with should be obvious along the way.

NOTE: The USB port map isn't 100% correct right now. Some ports seem to only work with HID devices, others do not work with USB 3.x hubs like those on my monitor.

BIOS / UEFI Settings​


I followed the above-linked post to the letter except that despite using the same motherboard, I could not find: Windows 8/10 Features (to set to Other OS).

A nuance is the linked post has an F-series processor with no integrated GPU yet the display output was set to IGFX. Mine is a K-series, which has an integrated GPU, but I would be using a discrete like the original post. Without this setting configured to IGFX, I would routinely get black screens leading up to the transition to the installer. It seems this critical then this is set to IGFX regardless of F, K, or use of a dGPU.

One setting I had to hunt down via some unrelated internet searches was disabling the VT-d option. MSI put this setting over in the Overclocking Settings section under one of the advanced CPU features area. Why VT-d is under "overclocking" is beyond me, but hopefully this helps others find it.

Preparing the EFI​


Download and extract an OpenCore release (0.7.1 RELEASE used here). Under the X64 directory, make a copy of the contents to be your new EFI directory. I've linked to the release version, however my EFI attached to this post is the DEBUG version, which was helpful with easing the friction when I ran into problems. Transitioning between the two is as simple as swapping the BOOT/BOOTx64.efi, OC/OpenCore.efi, and drivers files for the non-Debug/Release versions.

Adding Required SSDTs​

The linked guide shows SSDT-AWAC however in most recent releases this file is called SSDT-AWAC-DISABLE. Copy these files from Docs/AcpiSamples/Binaries to your EFI/OC/ACPI directory:

SSDT NameNotes
SSDT-AWAC-DISABLE.amlRequired for 400 series motherboards, appears to be required for 500 series too (corroborated against a few other Z590(i) guides elsewhere).
SSDT-EC-USBX.amlRequired for proper USB Power support
SSDT-PLUG.amlRequired for CPU and GPU Power Management

Adding Required Drivers​

Guides differ on these needs on a few small points, specifically the use of OpenHfsPlus vs. HfsPlus where different sources claim each has better performance and behavior than the other. I erred on the OpenCore documentation's recommendation and used the following from the OpenCore ZIP except where noted. You'll find these in your EFI/OC/Drivers directory.

Driver NameRequiredNotes
OpenRuntime.efiYESEvery guide identifies this as required and should be in-sync with the version of BOOT/BOOTx64.efi.
HfsPlus.efiYESNeeded for HFS volumes like the macOS Installer and recovery partition.

NOTE: The OpenCore release ZIP contains the OpenHfsPlus.efi; I frankly don't know who is "right" here so your mileage may vary.
OpenCanopy.efiOptionalProvides the Apple logo boot up screen, etc. It's not necessary in debug mode but is nice for a finishing touch.
AudioDxe.efiOptionalBoot chime support (again, a finishing touch)

You may remove the other .efi files from here.

Adding Required Kexts​

There are several differences between the above-linked guide and this one. Some are niceties and one is a necessity: USBInjectAll and its relationship to the XhciPortLimit quirk. Those do not work in 11.5.1, so I included those related changes when getting my initial EFI effort together, and then used Hackintool to produce my USB port map Kext. At that point, I could transition up to 11.5.1 and continue tailoring my EFI settings. I also did not need the FakePCIID related kexts to get the Intel I225V working in 11.5.1; it can be enabled with a boot argument (described later).

My resulting kext list in EFI/OC/Kexts then are based off that effort and the Comet Lake guide's links:

Kext NameRequiredNotes
LiluYESArbitrary patching
VirtualSMCYESEmulate VirtualSMC
Requires Lilu
WhateverGreenYESGPU Patching
Requires Lilu
AppleALCYESAudio support
Requires Lilu
SMCProcessorNOCPU Temperature monitoring, etc.
Requires VirtualSMC, included in that link
SMCSuperIONOFan speed monitoring, etc.
Requires VirtualSMC, included in that link
MSI_Z590i_UNIFY_USBPortsYESThis was produced using Hackintool and then imported. It is somewhat specific to this configuration in that the NZXT 210's front panel connector has a single pair of USB-C and USB-A connectors which are included in this map. The rest are the personas of the ports on the mainboard IO as well as the internal header that is connected to the X53 Kraken and the Broadcom WiFi Adapter, which uses a USB over PCIe for Bluetooth.

This file you can find in my attached EFI ZIP.

IMPORTANT: when you go to make your own map, do NOT choose Internal for the WiFi adapter (vs. USB3, etc.). Doing so will disable Bluetooth!

Editing the config.plist​

I used ProperTree exclusively for this effort. The linked guide suggests using a tool which the author says is no longer being maintained and will produce invalid configuration files, so that was enough to scare me off.

Copy the Docs/Sample.plist as your EFI/OC/config.plist and then open the file with ProperTree. Because you've already populated your drivers and ACPI directories, you can use CMD/CTRL+SHIFT+R to refresh config.plist which will automagically add references to both.

ACPI>Patch
This is identical to the linked post with this one missing detail: the post suggests the TableSignature is DSDT however that field must be a DATA type, which is 44534454 (hex). See the attached EFI for the whole block of patches you can copy-paste between ProperTree instances to simplify inserting these entries.

Booter>Quirks
QuirkEnabled
DevirtualiseMmioYES
EnableWriteUnprotectorNO
ProtectUefiServicesYES
RebuildAppleMemoryMapYES
SetupVirtualMapNO
SyncRRuntimePermissionsYES

DeviceProperties>Add
My setting is different from the original post in that I have a K-series with an iGPU but I'm using a dGPU. Per the Dortania Comet Lake guide, the appropriate setting then is 0300C89B (Hex). I also have no need of the i225-V -related patch (since I'm on Big Sur 11.5.1). Finally, I'm trying to get USB-attached HID devices to wake the device from sleep, so my two DeviceProperties entries are:

DevicesKeyValueTypeNotes
PciRoot(0x0)/Pci(0x2,0x0)AAPL,ig-platform-id0300C89BDATAThe iGPU is used only for computing tasks, not driving a display.
PciRoot(0x0)/Pci(0x14,0x0)acpi-wake-type01DATAPer the Dortania troubleshooting guide, this property should be enough to map the HC1 to the ACPI wake-up functionality, however in practice this made no difference for me. Expect this to change / no longer be necessary and it is specific to the MSI Z590i UNIFY.

Kernel>Quirks
QuirkEnabled
AppleXcpmCfgLockTrue
CustomSMBIOSGuidFalse
DisableIoMapperTrue
LapicKernelPanicFalse
PanicNoKextDumpTrue
PowerTimeoutKernelPanicTrue
XhciPortLimitFalse

A difference here is that I do not have XhciPortLimit set because it breaks 11.5.1 (in concert with USBInjectAll). This quirk is no longer needed for me since I went through the process of mapping the USB ports.

Kernel>Add
The linked guide suggests making changes here however the CMD/CTRL+SHIFT+R populated this for us.

Kernel>Scheme
In OpenCore 0.7.1, the settings provided in the original forum post are actually the defaults, so nothing changes here.

Misc>Debug
The Comet Lake guide suggests setting AppleDebug, ApplePanic, and Target to be True, True, and 67, respectively. I haven't investigated the impact of these if using Release vs. Debug binaries from OpenCore. I suspect these are "no op" under Release.

Misc>Security
The Comet Lake guide suggests setting the following:

OptionValue
AllowNvramResetTrue
AllowSetDefaultTrue
ScanPolicy0
SecureBootModelDefault
VaultOptional

IMPORTANT: The Value for Vault is literally the string Optional, not that setting it is optional.


NVRAM>Add>7C436110-AB2A-4BBB-A880-FE41995C9F82
Edit the following:

OptionTypeValue
boot-argsSTRING-v keepsyms=1 debug=0x100 alcid=11 agdpmod=pikera dk.e1000=0
prev-lang:kbdSTRINGen-US:0

Notes:
  1. The -v and keepsyms=1, debug=0x100 are all related to debugging options to get verbose mode and logs. Once you're ready to have the apple log, switch to release binaries and drop these arguments, add in OpenCanary and refresh your config.plist (CMD/CTRL+SHIFT+R).
  2. The alcid=11 per the original post and the Comet Lake guide are required to map the onboard audio device to the AppleALC.
  3. The agdpmod=pikera option is specific to this series of AMD GPU. This was missing from the original guide but required in my case, otherwise I would get a black screen instead of the installer window.
  4. OpenCore's sample.plist has the data type for prev-lang:kbd as DATA. Change it to STRING to use this value (or some other value), otherwise the installer will be in Russian.
  5. For macOS 11.5.1, (really, starting with 11.4.x IIRC), you no longer need kexts and device properties to get the I225-V to function, nor do you need. the widely-posted kernel patch. Instead, dk.e1000=0 will get the device detected. You'll then need to change its setting in Network Preferences in order for it to work properly (see below).
PlatformInfo
The only thing necessary here is to populate the Generic fields with those provided by GenSMBIOS to mimic, in my case, an iMac20,1 since I'm using an i7 processor (or i5 as the linked guide suggested). The Comet Lake guide confirms this as you're trying to pick a configuration that most closely mirrors an existing device matching your hardware.

One key nuance in this selection process is finding a generated configuration that is both valid and not registered yet. This is somewhat key in getting the various Continuity features functioning.

Preparing the USB​

This matches every other guide out there. You want to first use Disk Utility to format your thumb drive to APFS and GUID partition table. Then run the macOS installer's media creator app against that volume (mounted/named MyVolume here):

Bash:
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

Once finished, you can use MountEFI to mount the EFI Partition. You can then copy your EFI folder to that volume (i.e., in that Finder window representing your EFI volume, you should have a folder EFI with BOOT and OC under it).

When you boot your system the first time, be sure to select Reset NVRAM from the OpenCore Menu. Do it again for good measure, then let it run the installer.

Installation​

This should be completely vanilla, nothing crazy. Use Disk Utility to setup your hard drive and run the installer. It should reboot a few times. As it goes, it will switch from booting the Install macOS ... to macOS Installer... (I believe was the wording) and finally Macintosh HD (if that's what you called your installation volume.

Post-installation: I225-V Ethernet​

This device will be detected and even pull an IP address via DHCP (as long as you unplug/replug the ethernet cable) but it'll basically be dead. It might pull a packet or two, but it just flat won't work reliably until you:
  1. Open the System Preferences -> Network and select the Ethernet device
  2. Choose Advanced...
  3. Pick the Hardware tab
  4. Under the Configure drop-down, choose Manually
  5. Under the Duplex drop-down, choose one of the first two options (that do not say energy-efficient-ethernet, which apparently means conserve energy by not transmitting...I guess)
At this point it should be working fine.

Post-installation: Enabling TB3/4 w/ HotPlug​

TBD/WIP - I have not attempted the guides here on elitemacx86 or elsewhere, yet.

Troubleshooting: Wake on USB​

The Comet Lake guide suggests using the DeviceProperties change detailed in the above instructions, however it currently has no effect on my system. This is a TBD/WIP.

Hi!
I'm Using a MSI MEG 590 ACE, which is the ATX version of the MSI Z590i UNIFY. Same chipset, Same USB Ports, Same compatibility, TB4, More PCI-E Ports.
At a Start, I used the guide you mentioned to try to get it run, but had no luck, some things mismatch. After a week thinking, "oh my God, this is gonna fail..." I finally got it working following pieces of that guide, dortania's and some posts of another forums.
But, some things were different from the guide.
Integrated Wifi and Bluetooth doesn't work (Intel AX210)
Thunderbolt Hotplug didn´t work (TB devices are recognized only if you plugged in a TB device while the CPU is off and, then, turn it on). So, this guide is good for MSI MEG Z590 ACE too.
After upgrading to Big Sur 11.3, SURPRISE! USB does not work anymore, so I replaced XHCI-unsupported with a custom version that I found. USB were back, except thet USB-C and ethernet does not work anymore along the USB ports in the same line.
I Got to your guide and exchanged the "Intel Wifi6 AX210" wireless card with an "Intel Wifi6 AX201" from my laptop (I use windows on it, so compatibility is not an issue, in fact, my network performance was slightly improved hehe) using your instructions (thank you, by the way) and following this compatibility list to use OpenIntelWireless
for now, I don't have any thunderbolt device to make test so I wonder
Did you tried plug a thunderbolt device while the computer is off and, then, turn it on? How went that for you?
I'll be making more testing and report if find something useful.
Thank you again for your aportations!

I wish to share the bios screens that I took so maybe could help anyone on finding anything.
Also, I Tested your EFI on a USB with the Big sur 11.5.2 installer and got this image
WhatsApp Image 2021-08-16 at 4.22.29 PM.jpeg

I Tried to install from scratch in a fresh NVME but doing so makes the installer freezes in this screen or, with another USB, Gets up to the instalation screen, starts the instalation and, near the 13 minutes left, freezes again.
Funny thing is, If I use the nvme wich already has the OS, it boots normally...
I'd like to do a fresh install, but if it is not possible, maybe is wise to keep this.
Anyway, may you look my bios settings and compare with yours? I think I may be have somethin misconfigured.
Thank you!

The TB works like a charm. At cold boot, after boot. Even, if no device is plugged at boot.

Since Big Sur 11.3 and later, it's mandatory to map your USB ports.

I was seeing this around the time I realized I had to set the startup display to the iGPU rather than dGPU (the linked guide stated this but I forgot to do it) as well as when I was fiddling with the DeviceProperties for the iGPU. However, I have not attempted the 11.5.2 update; I'm still back at 11.5.1. I appreciate this heads up though!

I still haven't gotten around to testing TB or trying to resolve what's wrong with my port map.

As for your ethernet not working after the update to 11.3, it was around that time that the various methods started behaving differently. I've since lost the link to the thread on a different forum, but around that time, the FakePCIID route required various different changes to the DeviceProperties that point it to the NIC. Where we normally have a DATA field, some were having success using STRING as the type, others were finding they had to put both the VID and PID as the number, etc. I lost the plot on the 3+ variations people were each having success with until someone posted that at 11.5.1 they only had to do the boot arg change (as shown in my post). Since my existing drive from an old Mac was 11.5.1 already, it was my target version as it was so I basically skipped trying to fix any intermediate problems between 11.2.3 and instead focused on the USB port map so I could run through the 11.5.1 installer to verify the bulk of other features worked before I moved my drive over.

@childgear I updated to OC 0.7.2 release and then macOS 11.5.2 without much trouble. I followed these instructions and fixed the two minor issues with my config.plist for the version difference.

I cannot find in my notes exactly where I fixed that graphics lock-up glitch in my setup though. Are you running one of the graphics cards that requires setting the AMD graphics driver name in the bootargs like I am, or are you running the integrated GPU?

Than You @btgoodwin09
I did a cleanup on my file and the kext folder. Deleted the FakePCIID and added some partches. Ethernet now works fine (with the settings posted).
WLAN Worked fine after replacing Intel AX210 with AX201 (Since AX210 is not compatible) and using ITLWN and Heliport, Bluetooth worked well after using IntelBluetoothFirmware kexts with its noted limitations
( openintelwireless.github.io )
I got rid about USBinjectall.kext, disabled de XhciPortLimit quirk and used your MSI_Z590i_UNIFY_USBPorts.kext in replacement. All The USB ports Works, but as USB 2.0
USBC/Thunderbolt is a strange issue, The right port can detect USB-C devices with no problem, but Left port can't. I think left port can detect thunderbolt, but still no have any thunderbolt device to test it (maybe tomorrow a friend will borrow me a thunderbolt dock). For now, I'm focussed on fix the USB3.0 compatibility, but I'm still a little confused on how to do the usb port mapping (Can you point me to your source of info so I can learn it too?)
As for the graphic card, I'm using a Gygabyte Radeon RX 570 (my processor is core i9 10900F so it has no iGFX, so I must use dGFX but, as noted in the guide, the bios says the primary video outputs through iGFX).

Hi, can you share the EFI used to mapping USB?
I try to make an macOS 11.2.3 USB installer with USBInjectAll, XHCI-unsupported.kext and set XhciPortLimit to YES, but the suck at "still waiting for root device".
With the EFI in installer to boot onboard OS, the USB devices is not working.
Thanks.
