HP z800 Ventura (trying to follow successful instructions from another user, but not working for me) - Can anyone help?

[GuyEvans]

Hello, I was hoping someone might be able to help me please.

I'm struggling to get a working bootable version of Ventura.

 

I have a HP Z800 computer with 28GB of RAM

250GB SSD Drive (formated to Mac OSX journaled - GUID)

Sapphire RX580 GPU (Mac Compliant)

BCM94360CS2 Wifi Card and PCI Express Adaptor (Mac Compliant)

 

and I'm trying to follow these successful instructions from another member on here.

Here is the link below:

 

 

I've been following the Open Core Legacy install instructions, and I have got Ventura copied over to my 16GB USB INSTALL STICK.

I've created the EFI Folder by running the following command in Terminal :

 

sudo ~/Downloads/OpenCore/Utilities/legacyBoot/BootInstall_X64.tool

 

(It creates an EFI folder containing a file called 'Boot' (not bootX64) could this be part of the problem?

 

I've copied the EFI folder over from the post (linked above), and have changed the serial number by loading in Open Core Auxiliary Tools / Pi and clicking 'Generate'.

 

But when I go and try and boot my machine, it boots to this screen:

I don't see my SSD at all.

 

 

If I click on Install MacOS Ventura and it runs in verbose mode and then the screen goes black after a few minutes (but still displays a signal on my monitor).

Sometimes it also reboots.

 

I've attached my efi folder, and any help would be great.

I'd be so happy if I could get a working Ventura on my system.

 

This must be possible, somehow? I've got an identical system, apart from my mac compliant Wifi card, and my RX580 (not RX570) - although both GPU are mac compliant.

 

Thanks in advance if anyone can help me. I've been trying so long to try and solve this, but have only basic knowledge.

you may try my EFI, you should change serial number, if it’s working for you.

Hello, I tried your EFI folder with a new serial and it boots to the screen with EFI and 'Install MacOS Ventura'.

 

But when I try to install, it shows the apple logo and progress bar, but stops then and then the screen goes black. It doesn't reboot but just has a black screen. I can't see the Hard Drive activity LED light blinking either.

 

 

I'm not sure how to debug this. Any help would be much appreciated.

 

I have an almost identical system to yours.

HP Z800 and AMD Radeon RX580 GPU (Sapphire).

I was really hoping I could get this to work, and I'd be so grateful if anyone can help me solve this.

Thank you so much I shall give this a try later today. I'm really grateful for your reply.

 

Many thanks.

I tried the EFI folder you attached and Open Core boots to boot screen, but if I choose 'Install MacOS Ventura', then my system reboots after 2 minutes of the verbose boot text on screen.

 

This is the error log: I hope someone can help me with what this means?

 Did you look on github for an EFI to find a close match to your hardware?

Hi thanks,

Yes the EFI folder is almost identical to my own system (Same computer HP Z800, same GPU, different WIFI - but mine is also mac compliant wifi card from Macbook Pro (with PCI Express adaptor).

 

I'm knowledgable on Hackintosh but not so much with OpenCore.

I was assuming this EFI would work straight away, as once again my sysem is almost identcal to the user: Sok5 (who kindly shared their EFI).

for fresh install latest Sonoma 14 with my EFI. I have USB EFI installation and post EFI.

you need to download python 3.11.4 and latest OpenCore legacy Patcher

1. use USB EFI to install Sonoma when it's finish and successfully boot your OS.

 

2. install Python 3.11 and then OpenCore Patcher for WiFi and GPU. reboot after you done.

 

3. when your computer boot up, you can edit USB EFI config.plist or copy and paste from post EFI.

     edit config.plist=>boot-args -v -no_compat_check amfi_get_out_of_my_way=0x1 -amd_no_dgpu_accel  keepsyms=1 -lilubetaall

     to -v amfi=0x80 keepsyms=1 -lilubetaall -amfipassbeta

4. May need to use OpenCore Patches again for your GPU.

Wts the wifi card you use?

[cankiulascmnfye]

As far as WiFi is concerned: the Broadcom card requires Post-Install root patches in macOS Sonoma which need to be applied with OpenCore Legacy patcher. If the card is not detected by the patcher you have do use a workaround to enable the patch as explained here: https://github.com/5T33Z0/OC-Little-Translated/blob/main/14_OCLP_Wintel/WIiFi_Sonoma.md

@sok5USB3 PCIe Inateck KU5211 will works for Bootable USB right ?, Have you used previously mapped your USB ports for that Inateck PCI card ?, i am asking Because HP Z800 has USB controller 1.1 (UHCI), or that card uses GenericUSBXHCI Driver from Sonoma ??

If Possible please share ioregistry / System Profiler like this screen shot

I see Below error and looks like lost keyboard and mouse power and access. Do I need usb3 to proceed for sonoma ?

[sok5]

Yes, I used on board for bootable usb (installation) and usb3 for keyboard and mouse during installation, after installing completed. I used OpenCore legacy patcher, on board usb is working fine after that. I ran in the same problem. When installation completed, it reboot from 5-10 times.

Hi, thank you for all your help. I was able to install sonoma but without working internet for patching t919 card.  How did you patch it ?

I have installed ventura successfully though and is working .

 

Both versions with rx580 I was only able to power 1 monitor and 2 other hdmi connected  monitors are not working and seems black and issues with refresh rate.  How did you solve the extended monitors issue ?

need to download OC legacy patcher and python 3.11.4  from your working wifi.

install python 3.11 first and then OC legacy patcher after.

make sure you edit config.plis

Thanks for this, I'm a bit late seeing this post so will give this a try.

Massive thanks to everyone for sharing information and help.

 

I will give this a try this week. Thanks again!
