Apparently it is possible using Clover as a boot loader (Proxmox VE 6?), see: https://forum.proxmox.com/threads/osx-vm-el-capitan.62890/

For anyone following this thread, maybe you have an Asrock Creator TRX40 mobo, I will provide some updates here: 1. I changed my WiFi card to Broadcom as recommended by ND to get BT/WiFi, however, after this hardware change the OpenCore install of Catalina described in the earlier part of this thread would no longer boot. 2. As I want to install more than one OS on my work station I decided to switch to Proxmox 7 VE and I have successfully installed BigSur OS as a virtual machine in proxmox 7 following the guides here - https://www.nicksherlock.com/2020/04/installing-macos-catalina-on-proxmox-with-opencore/ https://i12bretro.github.io/tutorials/0551.html Please use both guides, while the second guide is currently up to date it does miss some important steps, if you don't replicate exactly using both guides your MacOS.iso may not install. There is also a YouTube video to accompany the second guide, clearly NS is a legend and is the moving force behind both of these guides. I will try to provide some key points on the post VM install of BigSur OS as my contribution to the community here to benefit those of you who need guidance using the most recent versions of Proxmox VE and OpenCore on a TRX40 mobo. I am also very busy with work so when I have time to customise my system and provide some posts here that may help you.

Thanks very much for taking the time to help. I will setup the debug now and follow the threads here. Should be fine - another TRX40 user/machine has just been born!

success with Catalina! I reset the CMOS to make sure all drives and partitions were visible in the BIOS and used a different USB port and worked no problem. Thanks very much Fabiosun! I guess I need to add the additional kexts to the EFI partition on the Hard Drive now to get bluetooth etc.. working. Very happy!

Thanks a lot for the check, I have not tried the MMIO edit config.plist yet - so far the problem is the same and re-occurs regardless of EFI and OsX version (I have tried High Sierra and Catalina) - OpenCore boots OK, always freezes on the initial install with 2 minutes to go (please see photo) All I want to do is install a functional version of OSX. I am going to download BigSur next but i think the problem is external to Opencore. According to Dortania freezing with 2 minutes to go is an NVRAM issue. Thanks

Hi, I have attached the MMIO edit based on the config.plist from ND, with the all patches config.plist version and my own ACPI generated by SSDTime - it won't boot OpenCore without these. thanks a lot. J config.plist.zip

Yes I appear to be having problems with all drives disappearing from the BIOS Boot menu after each attempt to install with OpenCore - actually I have never selected the USB EFI partition within the BIOS to boot OpenCore, it boots automatically after exiting BIOS and this may explain the problems. Recently I have to reset the CMOS to see the bootable drives again after an attempt with OpenCore and this clears all the BIOS settings. So next attempt I will boot by selecting the OpenCore EFI partition in the BIOS first. Here is my MMIO list, 'above 4G decoding enabled', FAstboot, Secure boot and CSM are all off and USB XHCI enabled in FCH and Chipset. I will post the config.plist tomorrow as it is late here now. thanks 0xC2500000 = 3260022784 0xC3580000 = 3277324288 0xDA100000 = 3658481664 0xFA180000 = 4194876864 0xFA300000 = 4197449728 0xFEA00000 = 4271898624 0xFEC00000 = 4273995776 0xFEC10000 = 4274961312 0xFED00000 = 4275044352 0xFED40000 = 4275306496 0xFED80000 = 4275568640 0xFEDC2000 = 4275838976 0xFEDD4000 = 4275912704 0xFEE00000 = 4276092928 0xFF000000 = 4278190080

OK thanks, I did read the thread on how to edit but interpreted this too literally to not enable all entries with 'skip 0'. Yes I have a number of logs from Opencore but I will check again with 'above 4G decoding' enabled. I have set up the BIOS according to the Dortania guide for AMD threadripper. OK I will post by tomorrow. Thanks a lot. J

I only have the last log from when I was trying to install High Sierra with opencore 0.7 (attached). The EFI from ND does not appear to be the debug version as no log was generated. One thing I noticed is that if I reset my CMOS internal installer USB becomes a boot option in BIOS as does the internal NVME - currently neither are being detected in the BIOS as a boot volume. thanks J opencore-2021-07-29-100531.txt.zip

Hi, I have tried, I used the EFI from the link above provided (courtesy ND) with minimal patch config.plist and my own ACPI generated by SSDTime, however alas it still freezes at 2 minutes remaining on the initial install of OsX onto the target HD, this time I used Catalina. So this is the same problem I keep having - I will try disabling 'above 4G decoding' and enable CSM as suggested but seems to me this still relates to the NVRAM issue. I will also tried using a different USB port assuming USB I use becomes broken during the install. Very frustrating! I did check the MIMIO list edit instructions however all my entries (22) are 'skip 0' and so not enabled. Any further suggestions welcome. thanks

Thanks Fabiosun, I am enlightened now. I will carefully study these threads and try again after following the recommended steps. Will report back here once I make significant progress. Ciao Jude

Hi Fabiosun, thanks for the prompt reply, very appreciated. I have attached my complete EFI. thanks Jude EFI.zip

Hi SQA, did you get your build fully functional and stable? I am have a very similar build using Asrock TRX40 Creator, 3970x, DDR4 RAM, 2TB Sabrent 4 NVMe SSD and Asus nVidia GeForce G710 1GB GDDR5,PCIe graphics card (metal compatible) as its a workstation build. I have being trying to install using OpenCore 0.7 but I keeps crashing with 2 minutes to go, boots OpenCore fine and obviously installer starts - apparently this relates to NVRAM and I have tried to disable 4G coding but same problem + the trouble shooting steps suggested in the Dortamia guide under 'user sopace issues' relating to this. Done the sanity check on config.plist and checked kexts etc.. and all is in order. Additionally I have used SSDTime to create custom .aml files. So I am stuck, I have tried High Sierra and Catalina with identical results. If any experienced forum members read this any advice would be appreciated! thanks PS I was planning to emulate this thread and see if it works so interested to know how you fared. My bios is also up-to-date.
