The Build

Inside Case.jpg


Background
Sadly, a few months ago, the motherboard in my old Haswell build died after about 8 years, so I recently made a new Comet Lake build. I went with a Z490 motherboard and a Comet Lake CPU because those are the last Intel chips that are natively supported by macOS.

ASUS Z490-A Prime Motherboard
I chose this board because it’s popular for Hackintoshes, so it seemed like it would be easier to find solutions to issues than other motherboards.

Intel i7-10700K CPU
I probably would have been fine with an i5-10500 or i5-10600, but the i7-10700K was on sale for cheaper than I could find for the i5 CPUs, so I went with that.

Fractal Design Meshify 2 Compact Case
I wanted a case that was smaller than the huge Fractal Design Define R4 case I had for my old build. I decided on the Meshify 2 Compact based on reviews and the quality of my old Fractal Design case. I've never cared about showing off my components with a window panel, but I liked the look of the white case, which only came with a window panel.

Noctua NA-CH4 chromax.white Heatsink Cover
After setting everything up and looking at the components, though, I decided to get Notcua’s white CPU cooler heatsink cover to match the case. In hindsight, I think I might've preferred the look of white memory sticks as well, but black was cheaper.

Noctua NA-SYC1 chromax.Black Splitter Cables
One annoying thing that I realized while putting everything together is that my case has 3 fans, but my motherboard only has 2 headers, so I had to buy a Y splitter cable for the front fans.

Case Drive Cage
The case has a removable drive cage that I needed for my HDD. I actually didn't think that the cage would fit with my PSU based on the specs for the case, but it did, albeit with cables crammed tightly between the cage and the PSU.

Old HDD
I also realized that while I'm reusing many parts from my old build, my HDD is the only original part. Everything else is an upgrade or replacement. I'm a little surprised it's still running considering I originally had 2 of them, and the other one died after a few years. It will be the first thing to go (along with the drive cage) when I upgrade my drives (see below).


Upgrades I’m Considering

Drives
The first upgrades I plan to make to my build will be upgrading my startup disks from SATA SSDs to NVMe M.2 SSDs. Then one of my SATA SSDs will be used for additional storage if needed, while the other will be used for the external clone of my macOS startup disk, replacing the HDDs I currently use for both. Maybe down the road SSD storage sizes will become large enough and prices low enough that I'll be able to upgrade my Time Machine backup as well.

I upgraded both of my SATA SSDs to NVMe M.2 SSDs. See the Upgrades section above, Update 7, and Update 11.

Graphics Card
If prices ever come down, I will probably eventually upgrade my graphics card.

I upgraded my graphics card to an RX 6600. See the Upgrades section above and Update 14.

Memory
I debated getting 32GB of memory but decided against it due to costs, so I may add another 16GB in the future.


Guide

I referenced Shiloh’s Build for Tristan guide, which uses the same motherboard (and a few other parts), but I primarily followed the OpenCore Guide and set up my EFI folder from scratch.

Note that I've attached 2 EFI folders to this guide for reference in case they're helpful to others: one for the macOS USB installer and one for my internal SSD that includes changes made during Post-Installation.

macOS USB Installer

I followed the OpenCore Install Guide to create my macOS USB Installer and followed the Desktop Comet Lake section of the guide to create my config.plist. The EFI folder for my USB installer is attached to this guide. Here are some important things to note:
  • macOS Version and USB Port Mapping: The port limit quirk needed for mapping USB ports is broken in macOS 11.3 and newer, so you must download an older version to map USB ports.
    • I used Munki's InstallInstallMacOS utility to download macOS 10.5.7 Catalina (see the OpenCore Guide for more information).
    • After later mapping USB ports and completing the rest of post-installation, I updated macOS to Big Sur (see further down in this guide).
  • Kexts
    • If you have an NVMe SSD, make sure to add the NVMe kext. It's not included in my EFI folders since I have a SATA SSD.
    • SMCProcessor and SMCSuperIO are optional kexts bundled with VirtualSMC that are only needed for displaying system stats in apps like HWMonitor, HWMonitorSMC2, or iStat Menus. You can exclude them if you don’t care about stats.
  • SMBIOS
  • Audio: I used audio layout ID 7 based on Shiloh's guide, and it worked for me. It’s possible other layout IDs may work, too.
  • dGPU
    • The RX 580, my original GPU for this build, has been supported since macOS Sierra.
    • The RX 6600, my current GPU, is only supported in macOS 12.1+ Monterey.
      • This GPU, along with all AMD 5000 and 6000 series GPUs, also requires the agdpmod=pikera boot argument to prevent the screen from going black on the desktop:
        • In config.plist, under NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82, in boot-args, add agdpmod=pikera.
      • See Update 14 for more information on the RX 6600.
  • iGPU: Because I only have one display, which is connected to my dGPU, I set my iGPU to only be used for computing tasks.
    • Under DeviceProperties -> Add -> PciRoot(0x0)/Pci(0x2,0x0) in config.plist, set AAPL,ig-platform-id to 0300C89B.
    • If you are using your iGPU to drive a display, you’ll need to set this up according to the OpenCore Guide.
  • Ethernet: I had no Ethernet after installation because I set up a couple of things wrong in my config.plist. Make sure you set these options in your config.plist to get ethernet to work (they’re included in both of my EFI folders).
    • Under DeviceProperties -> Add, use PciRoot(0x0)/Pci(0x1C,0x4)/Pci(0x0,0x0) and NOT PciRoot(0x0)/Pci(0x1C,0x1)/Pci(0x0,0x0) like I did at first. Note that just one number is different: 4 instead of 1.
    • Under NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82, in boot-args, include dk.e1000=0.
      • In macOS 12.3 Monterey, the ethernet boot argument changed to e1000=0. See Update 6.

Windows USB Installer

Since my motherboard died, I didn't have a Windows computer to create a Windows 10 USB installer. Instead, I followed these steps to create the installer on my MacBook Pro.
  1. Format a USB drive for the installer.
    1. Insert the USB drive.
    2. Open /Applications/Utilities/Disk Utility.
    3. Select View > Show All Devices.
    4. Highlight the top-level device for the USB drive in the left column.
    5. Click Erase.
    6. Under Name: name it whatever you want.
    7. Under Format: choose MS-DOS (FAT).
    8. Under Scheme: choose Master Boot Record.
    9. Click Erase.
  2. Download the Windows 10 Disc Image from Microsoft.
  3. Copy the disc image to the USB drive.
  4. Double-click on the disc image file to mount it.
    1. Open /Applications/Utilities/Terminal.
    2. Type diskutil list and press Enter.
    3. Find the disk number for your USB drive. It should be something like disk1 or disk2.
    4. Type diskutil eraseDisk MS-DOS "WINDOWS10" MBR diskN but replace N with the disk number (e.g., if my drive was disk2, I would type diskutil eraseDisk MS-DOS "WINDOWS10" MBR disk2) and press Enter.
    5. Copy all the files to your USB drive except for one that is too big for a FAT32-formatted drive: Type rsync -avh --progress --exclude=sources/install.wim /Volumes/CCCOMA_X64FRE_EN-US_DV9/ /Volumes/WINDOWS10 (note that if you downloaded a different language than English (US), then you will need to change EN-US to match what’s in the name of your disk image volume) and press Enter.
    6. Install Homebrew if it’s not already installed: type /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" and press Enter.
    7. Use Homebrew to install wimlib: Type brew install wimlib and press Enter.
    8. Use wimlib to split up and copy the one large file to your USB drive. Type wimlib-imagex split /Volumes/CCCOMA_X64FRE_EN-US_DV9/sources/install.wim /Volumes/WINDOWS10/sources/install.swm 4000 and press Enter.
You should now have a bootable Windows 10 USB installer named WINDOWS10.

BIOS and Windows Drivers USB

I read a lot of reviews that said this board (and others with I225-V ethernet) has issues with ethernet not working out of the box in Windows and requires an updated driver, so in addition to the latest BIOS, I also downloaded all the latest drivers from the ASUS website to a FAT32-formatted USB drive. It turned out that my ethernet didn't work initially in Windows either, so this was a helpful step.

BIOS Preparation

  1. Update BIOS(I’m using ver. 2301)
    1. Insert the USB drive with the BIOS file and boot up the computer.
    2. Press Delete or F2 to enter BIOS. (note that to make F keys work on my K750 keyboard, I have to hold the fn key at the same time, so you may need to do the same)
    3. Press F7 or click Advanced in the bottom right corner to enter Advanced Mode.
    4. Go to the Tool menu.
    5. Select ASUS EZ Flash 3 Utility and press Enter.
    6. Select your USB drive and press Enter.
    7. Select the BIOS file on your USB drive and press Enter.
  2. (Optional) Load my BIOS profile. I attached two BIOS settings files to this guide. BIOS_setting.txt is a readable text file that lists all of my BIOS settings for reference. BIOS_Profile.CMO is a profile that can load all of my settings into your BIOS. If you choose to do this, I recommend using the same BIOS version as me (2301) and reviewing all the settings after loading them.
    1. Download BIOS_Profile.CMO to a USB drive.
    2. Insert the USB drive and boot up the computer.
    3. Press Delete or F2 to enter BIOS.
    4. Press F7 or click Advanced in the bottom right corner to enter Advanced Mode.
    5. Go to the Tool menu.
    6. Select Load/Save Profile from/to USB Drive.
    7. Select your USB drive and press Enter.
    8. Select the BIOS_Profile.CMO file on your USB drive and press Enter.
    9. Review the settings that have been loaded.
  3. Adjust BIOS settings based on the OpenCore Guide.If you loaded my BIOS profile, I recommend reviewing these settings to make sure they’re correct. These are the important settings and what menus they’re locating in:
    • Ai Tweaker
      • Ai Overclock Tuner = XMP II (loads my RAM’s default XMP profile and sets the frequency to 3200 MHz rather than the default of 2666 MHz)
    • Advanced > CPU Configuration
      • Intel (VMX) Virtualization Technology = Enabled
      • Hyper-Threading = Enabled
    • Advanced > System Agent (SA) Configuration
      • VT-d = Disabled
    • Advanced > System Agent (SA) Configuration > Graphics Configuration
      • Primary Display = PCIE (to use my dGPU for primary display)
      • iGPU Multi-Monitor = Enabled (even though I’m not connecting a display to my iGPU, this is required to use the iGPU for computing tasks)
      • DVMT Pre-Allocated = 64M
      • RC6 (Render Standby) = Disabled
    • Advanced > Thunderbolt(TM) Configuration
      • Thunderbolt(TM) Support = Disabled (can be enabled after installation if you have a Thunderbolt card)
    • Advanced > USB Configuration
      • XHCI Hand-off = Enabled
    • Advanced > Onboard Device Configuration
      • USB power delivery in Soft Off state (S5) = Enabled (Optional, for charging USB devices while in sleep)
    • Advanced > Onboard Devices Configuration > Serial Port Configuration
      • Serial Port = Off (note that my BIOS_setting.txt file incorrectly shows that Serial Port is set to Auto, but it should be Off)
    • Advanced > PCI Subsystem Settings
      • Above 4G Decoding = Enabled
    • Boot > CSM (compatibility support module)
      • Launch CSM = Disabled
    • Boot > Secure Boot
      • OS Type = Other OS
    • Boot > Boot Configuration
      • Fast Boot = Disabled
      • Boot Logo Display = Full Screen
      • Post Delay Time = 3 sec (Optional)
      • Wait For 'F1' If Error = Disabled (Optional)
  4. Save Changes & Reset.
    1. Go to the Exit menu.
    2. Select Save Changes & Reset and press Enter.

macOS Installation

  1. Disconnect all drives except for the one that will be your macOS startup disk.
  2. Insert your macOS USB installer drive and boot up the computer.
  3. Select your installer drive in BIOS.
  4. Select Install MacOS Catalina in OpenCore.
  5. Install macOS on your internal drive.

macOS Post-Installation

The final EFI folder for my startup disk is attached to this guide. This includes all the changes I made during post-installation:
  1. I followed the OpenCore Post-Install Guide to
    1. boot without the USB drive,
    2. make the audio layout permanent, and
    3. turn off verbose mode.
  2. I fixed the ethernet issue (explained in the macOS USB Installer section above). This fix is in both of my EFI folders.
  3. I fixed an issue where my computer was POSTing in safe mode on reboot
    • Under Kerne -> Quirks in config.plist, set DisableRtcChecksum to True.
  4. I mapped my USB ports (see below).
  5. I fixed my instant wake issue (see below).

Mapping USB Ports

I first attempted to map my USB ports using Hackintool and following The New Beginner's Guide to USB Port Configuration as I had done with my old build. However, no ports would show up in Hackintool, so I followed the OpenCore Post-Install Guide to map my USB ports with USBMap, where my ports thankfully showed up. I still had some issues getting my ports properly, but @Edhawk helped me sort it out (thank you!).

This motherboard has 26 total USB ports that show up in USBMap, but macOS only allows 15, so there are many possible ways one could map the ports. My USBMap.kext is included in my internal EFI folder for reference, but you will likely want to map your ports a little differently.

I chose to enable all of the High Speed (USB2 backward compatible) and SuperSpeed (USB3) ports for the headers connected to the front panel of my case. I set the USB2 header connected to my Wifi/Bluetooth card to type 255 (Internal). For the rear panel ports, I only enabled the SS ports for the USB3 ports and left the HS ports disabled, except for one that I connect to my monitor’s USB hub, to stay under the 15-port limit. I also enabled only one of the USB2 ports to stay under the limit. The diagram below shows which ports I’ve enabled (green ports are enabled and red ports are disabled).

Fixing Instant Wake Issue

My computer would not stay in sleep mode (even after mapping USB ports). I tried many fixes, but I eventually found one that worked. I used the GPRW Instant Wake Patch in the OpenCore Post-Install Guide to fix this issue (included in my internal EFI folder):
  1. Download the GPRW SSDT.
  2. Place SSDT-GPRW.aml under OC/ACPI in your EFI folder.
  3. Open your config.plist in ProperTree and select File > OC Snapshot to add the SSDT to your config.
  4. Under ACPI -> Patch in your config.plist, add the following new patch:
    1. The Key should be the next number in the list of patches. For me, that was 2. The Type should be Dictionary.
    2. Under the new patch, add the following (it may be easier to duplicate one of the existing patches in your config.plist and then replace the values):
Key Type Value
Base String
BaseSkip Number 0
Comment String change Method(GPRW,2,N) to XPRW, pair with SSDT-GPRW.aml
Count Number 0
Enabled Boolean True

Limit Number 0
Mask Data
OemTableId Data
Replace Data 58505257 02

TableLength Number 0
TableSignature Data


Instant Wake Patch.png


This fix keeps my computer from instantly waking when I put it in sleep mode. However, I discovered that I can't wake my computer with my mouse or keyboard, so I have to use the power button instead. I’m still trying to fix this.

Updating to Big Sur

With all the major issues resolved and USB ports mapped, it was time to update to macOS Big Sur.
  1. First, I updated my kexts.
  2. Next, since System Preferences wanted me to update to Monterey, which I'm holding off on for the moment, I used Munki's InstallInstallMacOS utility again, this time to update to Big Sur.
  3. Since the utility didn't have the very latest version of Big Sur (11.6.4), I used System Preferences to update macOS one more time.
  4. After all the updates were done, I used Migration Assistant to restore everything from the Time Machine backup of my old build.

Window Installation

  1. Disconnect all drives except for the one that will be your Windows startup disk.
  2. Insert your Windows USB installer drive and boot up the computer.
  3. Select your installer drive in BIOS.
  4. Install Windows.

Window Post-Installation

  1. Install drivers from the BIOS and Windows Drivers USB.
  2. Install Windows updates.
  3. Reconnect other drives.
  4. When you reboot, both the macOS and Windows disks should be listed in OpenCore.
  5. (Optional) If OpenCore is defaulting to the Windows disk, and you would prefer it to default to macOS:
    1. Boot into the macOS disk.
    2. Open System Preferences and select Startup Disk.
    3. Select your macOS disk and click Restart.

What Works, What Doesn’t, and What’s Untested

What’s Working in macOS

  • Restart/Shutdown
  • Sleep/Wake (resolved instant wake issue, but can only wake with power button)
  • dGPU
  • Native Audio
  • HDMI/DisplayPort Audio via dGPU (see Update 14)
  • Ethernet
  • Wi-Fi
  • Bluetooth
  • USB ports that I mapped
  • iCloud
  • iMessages
  • FaceTime (if DRM fix isn't enabled — see Update 15)
  • Continuity
    • Airdrop
    • AirPlay to Mac
    • Auto Unlock with Apple Watch
      • This was initially giving me an error when I tried to enable it, but when I tried again today (3/29/22), it worked. Maybe it was fixed when I updated to macOS 11.6.5.
    • Continuity Camera
    • Continuity Markup
    • Continuity Sketch
    • Handoff
    • Instant Hotspot
    • iPhone Cellular Calls
    • Sidecar
    • Text Message Forwarding
    • Universal Clipboard
  • Security
  • OpenCore GUI (see Update 3)
  • TRIM
    • TRIM isn't enabled by default for APFS SATA SSDs in macOS, and I initially didn’t enable it because I read that it slows boot times. However, I found that in disk speed tests, my write speeds were very slow (110 MB/s), but enabling TRIM (execute sudo trimforce enable in Terminal) improved speeds some (to 290 MB/s; see benchmarks below). It also only added about 5 seconds to the boot time.
  • DRM: iTunes movies and Apple TV+ (see Update 4)
  • Universal Control

What’s Not Working in macOS

  • Sleep/Wake: wake with keyboard or mouse
    • I tried all 3 methods for fixing Keyboard Wake Issues from the OpenCore Post-Install guide, but none of them worked.
  • DRM: Netflix and Amazon Prime
    • Note that Safari 14 and macOS 11 Big Sur are currently unsupported by WhateverGreen's DRM patches.

What’s Untested or Not Set Up Yet in macOS

  • iGPU to drive a display
    • As explained in the macOS USB Installer section above, I only have one display, which is connected to my dGPU, so I set my iGPU to only be used for computing tasks and have not tested using my iGPU to drive a display.

What’s Not Working in Windows

  • Time zone sync (resolved by @tech1eguy's fix)
    • My time is correct in BIOS and macOS. However, every time I boot up Windows, my time zone is wrong, and I have to manually sync my time. I’ve tried several fixes I found online, but the issue persists.
  • RGB customization (resolved by using SignalRGB — see Update 15)
    • I had this working initially and changed the motherboard’s RGB from the default rainbow colors to solid white. However, at some point, the RGB reverted back to rainbow colors, and when I went into the Armory Crate app, it showed that I had no RGB devices. I’ve tried uninstalling and reinstalling all the ASUS software, but the motherboard is still not showing up as an RGB device.

Something strange was going on with Unigine Heaven on macOS. Not only was the performance much worse on macOS than on Windows, but it was also worse than the same tests on my old build with the same GPU.

Blackmagic Disk Speed Test

My macOS SSD had really slow write speeds for some reason, which wasn't the case when I first got the drive. After enabling TRIM, write speeds improved but were still much slower than expected. I guess it's a good thing that I'm planning on upgrading to NVMe SSDs soon.

Update 2: FileVault

I followed the OpenCore Post-Install guide to modify my config.plist and enable FileVault. These settings are different than what's in the guide:
  • Misc -> Security
    • AuthRestart set to NO (the guide says you can optionally set this to YES so that a password is not required on reboot, but I opted to set it to NO for better security)
  • NVRAM -> Add -> 4D1EDE05-38C7-4A6A-9CC6-4BCCA8B38C14
    • UIScale (did not include because I have UIScale set under UEFI -> Output and the settings made no difference for my display anyway)
  • UEFI -> ProtocolOverrides
    • HashServices (did not include because it only applies to Broadwell and older)
  • UEFI -> Quirks
    • ExitBootServicesDelay (did not include because it only applies to Broadwell and older)
After updating my config.plist, I rebooted and turned on FileVault in System Preferences (Security & Privacy -> FileVault).

My latest EFI folder is attached for reference.

Windows time appears to be fixed now. Thank you!

However, method 1 did not fix my wake with keyboard/mouse issue. I'm going to try the other methods to see if they fix it.

Update 3: OpenCore GUI and Apple Secure Boot


I followed the OpenCore Post-Install Guide to set up the OpenCore GUI and enable Apple Secure Boot. Important things to note about each update below:

OpenCore GUI

Notes about OpenCanopy.efi:
  1. Make sure you use OpenCanopy.efi from the same build as your OpenCore files. In my case, that was 0.7.6.
  2. OpenCanopy.efi is under X64/EFI/OC/Drivers. Copy it to EFI/OC/Drivers in your EFI folder.
  3. After copying OpenCanopy.efi to your EFI folder, open your config.plist in ProperTree to set up the GUI according to the guide. Select File > OC Snapshot to automatically add OpenCanopy.efi to your config under UEFI -> Drivers.

Apple Secure Boot

CORRECTION: In OpenCore 0.7.4+, the Default SecureBootModel value to matches the SMBIOS model to fix Monterey updates, so there is no need to set SecureBootModel to j185 or j185f. After learning this, I have since changed SecureBootModel back to Default. If you are using OpenCore 0.7.3 or earlier, you can set the SecureBootModel value as I did below, but if you're planning to update to Monterey, you must update to OpenCore 0.7.4+ and set SecureBootModel to Default.

  1. [For OpenCore 0.7.3 or earlier only] First, I enabled SecureBootModel for the equivalent of "Medium Security" Secure Boot on a Mac. Make sure you choose the correct for your SMBIOS.
    • Under Misc -> Security
      • If you're using iMac20,1 for i7-10070K or lower (like me), set SecureBootModel to j185
      • If you're using iMac20,2 for i9-10850K or higher, set SecureBootModel to j185f
  2. Then, I generated my ApECID value, entered it under Misc -> Security -> ApECID (the OpenCore guide incorrectly states that it's under Misc -> ApECID), and personalized my system in recovery mode volume to achieve "Full Security".

My latest EFI folder with both the OpenCore GUI and Secure Boot updates is attached. Note that my config.plist in the attached folder does not include my ApECID value. You will need to generate your own value and enter it under Misc -> Security -> ApECID.

Unfortunately, methods 2 and 3 didn't work either.

Good stuff. I have a Z470-A prime MB, and i7-10700K CPU. Hoping on getting an RX6600-XT GPU soon... and 32GB of RAM.

It's all be going into a G5 case with Laser-Hive backplate.

I will be posting my build at some point over the next few months, I hope. I'm sure this thread will come in useful.

I'm considering an M.2 SSD for the system/apps, though it's probably a nice to have, if I can get the system running without it, I may be tempted.

Update 4: Fixing UI Scale and DRM

Fixing UI Scale

I previously tried to change the UI Scale to 2x because everything was so small in OpenCore and the FileVault login screen was so small, but changing the value for UIScale made no difference. That's because an NVRAM reset is required when changing the value. When I reset NVRAM, the change worked.

  1. In config.plist, under UEFI -> Output, set UIScale to 2.
  2. Reboot
  3. At the OC Picker, press Space and then select Reset NVRAM. The computer will reboot.
  4. After restarting, my computer booted into my Windows drive instead of my macOS drive.
    1. If this happens to you, restart again and press Delete or F2 to enter BIOS.
    2. Press F7 or click Advanced in the bottom right corner to enter Advanced Mode.
    3. Go to the Boot menu.
    4. Set Boot Option #1 to your macOS drive.
    5. Go to the Exit menu.
    6. Select Save Changes & Reset and press Enter.
  5. Upon restarting, the OC Picker and FileVault login screen should now be scaled 2x.
  6. However, at this point, the OC Picker was also defaulting to my Windows drive.
    1. If this happens to you, select your macOS drive and log in.
    2. Open System Preferences and select Startup Disk.
    3. Select your macOS disk and click Restart.
    4. The OC Picker should now default to your macOS drive.

Partially Fixing DRM

I had previously tried fixing DRM, but it didn't work, which was unsurprising since according to the OpenCore Post-Install Guide, "Safari 14 and macOS 11 Big Sur are currently unsupported by WhateverGreen's DRM patches." However, I found a workaround that fixed DRM for Apple TV+ and iTunes movies (but not Netflix or Amazon Prime). It involves applying an AMD GPU video decoder preference override in Terminal.

Be aware that the WhateverGreen FAQ on DRM patching warns that "This preference may not always be compatible with the rest of the operating system and may cause problems with other ways of hardware media decoding and encoding," and milmbr said that it "breaks FaceTime by not allowing remote video to stream and resulting in a "poor connection" message with audio but a grey screen." I don't have a camera to test FaceTime video with, and I haven't seen any other video issues yet. However, if you need to fix FaceTime or other video issues, remove the shikigva patch from your config.plist and then execute the following command in Terminal:
Bash:
defaults write com.apple.AppleGVA gvaForceAMDKE -boolean false

Enabling the Fix
  1. In config.plist, under DeviceProperties -> Add
    1. Add a new child with the dGPU device path: PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0) | Dictionary
    2. Add a new child under the dGPU device path: shikigva | Number | 80
  2. Alternatively, you can add the patch as boot argument
    1. Under NVRAM -> Add -> 7C436110-AB2A-4BBB-A880-FE41995C9F82
    2. In boot-args, add shikigva=80
  3. Reboot and run the following preference override command in Terminal to force the AMD DRM decoder for streaming services:
Bash:
defaults write com.apple.AppleGVA gvaForceAMDKE -boolean yes

DRM content should now play in the TV app.

Excellent work Gobias, very detailed and up to date will trying out your revised config very shortly.

Your update 3 worked well to until my ageing 580 Pulse decided to pulse no more! New Pulse will be here on Monday next.
