Big Sur on HP EliteDesk 800 G4/G5 Mini - The Perfect MacMini8,1 Hackintosh - Open Core

[deeveedee]

Asking for some volunteers to help determine the cause of H.265/HEVC "encoding not available" on the EliteDesk 800 G4 Mini (and similar systems) when running Big Sur. If you'd like to help, please do the following and report results in this thread as requested below:

1. Make sure you are running Big Sur (any version)
2. Install and run free version of VideoProc.app (click here for download)
3. Open VideoProc.app and navigate to Setting>Common>Options
4. Allow VideoProc.app to detect your hardware
5. Post the following:
   1. A summary description of your system with the exact CPU model (e.g. i7-8700 and not just Hexacore i7), total RAM (e.g. 32GB) and RAM configuration (e.g. 2 x 16GB), Physical Video Connectors (e.g. 3 x DP -> DigitalDVI -or- 3 x DP)
   2. A screen shot showing the full "Hardware Info Detected" screen as shown below. The screen should show your Processor, Graphics and OS Version and the detection results of both H264 and HEVC.
   3. A freshly captured IORegistryExplorer 2.1 dump (I will update my attached IORegistryExplorer 2.1 dump when I'm running Big Sur again (currently running Catalina).

My EliteDesk 800 G4 Mini summary description:

• CPU: i7-8700
• RAM: 32 GB (2 x 16GB)
• Physical Video Connectors: 3 x DP -> DigitalDVI (My displays are DVI so I use DP->DVI adapters)

EDIT: I have updated the attached screenshot and IORegistryExplorer dump with those collected while running BigSur 11.2.

Hello all,

I checked Intel PowerGatget on WIN/macOS
At WIN, I've got the same results as with SSDT-PLUG with "plugin-type", Zero and that should be right.
I could switch between these Version of SSDT-PLUG without Error.

I never could resolve the USB "high-current" Error. Tried OC since 063 release and nightlies.
This Error won't appear at the USB C Connector.
If you connect your Phone, would they switch to a USB3 (SS) Port in Hackintoshtool?

Multiboot
Platforminfo/Quirks UpdateSMBIOSMode=Custom or Kernel/Quirks CustomSMBIOSGuid=YES
Now works as it should for me and WIN got the same Hardware UUID as if I would start from BIOS.
Important is, that you create the second EFI, MSR and WIN Partition before you install WIN with CMD.

@Carstimann You specified i5-7500, but you meant i5-8500 (as indicated in your signature) - correct?

 

[Carstimann]

Hi, yes a mistake, delete it.

Did a fresh macOS 11.2 install without issues.

Post #1 now includes an attached draft EFI for OC 0.6.6 (OC0.6.6-EFI-r001). I used this updated EFI to upgrade to Big Sur 11.2 with no problems. Changes from the previous OC 0.6.5 EFI are as follows:

Changes in this EFI (from OC0.6.5-EFI-R002)

• Upgraded to OC0.6.6
• Replaced SSDT-MM81 with SSDT-DMAC (new SSDT only adds device DMAC)
• OC/Kexts contains multiple versions of USBPorts.kext. The default USBPorts.kext has 16 logical USB ports and requires config.plist Kernel>Quirks>XHCIPortLimit=1. Other USBPorts options are below.
• USBPorts.kext now labels SS03 and SS04 "Connectors" as TypeC. There is disagreement about this, but it is working for me and I suspect it's more cosmetic than functional. Refer to Hackintool context sensitive help for more info.
• Changed config.plist: Kernel>Quirks>XHCIPortLimit=1 (for 16-port USBPorts.kext). Use Hackintool to customize USBPorts.kext (to comply with 15-port limit) and change XHCIPortLimit to 0.
• Revised SSDT-XOSI.aml to be 'multi-boot friendly' - includes _OSI("Darwin") conditions
• Replaced Driver HfsPlus.efi with OpenHfsPlus.efi
• Upgraded Acidanthera kexts AppleALC.kext, WhateverGreen.kext, Lilu.kext
  • AppleALC.kext 1.5.6 -> 1.5.7
  • WhateverGreen.kext 1.4.6 -> 1.4.7
  • Lilu.kext 1.5.0 -> 1.5.1
• Changed config.plist: UEFI>Audio>VolumeAmplifier from 143 to 70 (lower boot chime volume)
• Changed config.plist: Added Kernel>Quirks>SetApfsTrimTimeout
• Changed config.plist: Added Misc>Boot>LauncherOption, LauncherPath, PickerVariant
• Changed config.plist: Added PlatformInfo>UseRawUuidEncoding
• Changed config.plist: Added UEFI>Quirks>DisableSecurityPolicy
• Changed config.plist: Removed Misc>Security>BootProtect

USBPorts.kext options included in this EFI:

• USBPorts-noHS14.kext: HS14 (internal Bluetooth USB) not included in port map - complies with 15-port limit, set XhciPortLimit=0
• USBPorts-16.kext: Includes 16 logical USB ports - exceeds 15-port limit, set XhciPortLimit=1 (not intended for production use)
• USBPorts.kext: same as USBPorts-16.kext

My advice about this BIOS update: After comparing the release notes for this latest BIOS update (2.15) to the previous BIOS update (2.14.01), I don't believe that this update is urgent - don't rush to install this. BIOS update 2.15 fixes the "After Power Loss" issue (which I have never seen) and updates Intel Reference Code as mentioned below. The other firmware is unchanged from 2.14.01 to 2.15. My advice: don't be the first to apply this BIOS update.

===============================================

There is a new BIOS update for the EliteDesk 800 G4 Mini (version 2.15). I am still running with BIOS version 2.14.1 and have not tested with the new BIOS version. The new BIOS (2.15) includes the following changes:

• Fixes an issue where "After Power Loss" in BIOS setup lost functionality after s3 resume.
• Update Intel Reference code to 7.0.74.20
• This BIOS upgrade package also includes the following firmware versions:
  • Intel Management Engine Corporate v12.0.70.1652 (Production)
  • Super I/O (SIO) 7.9.51
  • Intel VBIOS 9.2.1014 (2018/06/21)
  • Intel GOP 9.0.1075
  • USB Type-C PD firmware FW 6.8.0
  • Intel/Realtek PXE rom IBA CL v0.1.13
  • Intel/Realtek UEFI PXE rom EFI v0.0.19

EDIT: For those adventurous enough to try the new BIOS update, don't forget about the ACPI patch that I needed when I updated my G3 Mini BIOS. We haven't needed it on the G4 Mini, but a BIOS update may change that.

Spent the better part of the past hours updating everything on my 800G5 hack... BIOS update was a bit scary doing it from the UEFI BIOS as it went black or seemingly freeze even at one point without power for extended periods of time. I don't remember observing this in the past. For the G5 it is an upgrade from 2.08.

I then upgraded opencore 0.6.6 which had me dig into the new options for opencanopy to find a few resource files (icons and audio) needed to be updated to bring it back. I then adopted @deeveedee's ACPI and kext setups (except for USB, video and boot audio.) and all seems to be well. Now my HEVC doesn't appear to work.

CPU: i9 9900
RAM: 64GB (2x32GB)
3 DPs: -> 1 is connected to a monitor.

My iOreg dump attached.

Here the specs of my miniPC that unluckily lacks hardware acceleration H265 in Big Sur.

• ASUS Prime H310I-PLUS R2.0
• Intel Core i3 8100
• 2 x 8GB Tot 16GB DDR4
• SSD NVME 1TB
• tested with WEG 1.4.7
• Physical Video Connectors: 1x VGA
• Physical Video Connectors: 1x DVI
• Physical Video Connectors: 1x HDMI

H265 Hardware acceleration never worked in Big Sur BUT works in Catalina with the same configuration.
