Mac OS install on AMD Ryzen/INTEL (VMWare) Opencore - Improved Performance - Works with Tahoe / Sequoia / Sonoma / etc

[javi]

Hello, I'm trying to install macOS Sonoma using this guide, but I can't get it to work. What happens to me is that the installer never fills the bar of this screen; it constantly reboots around this:



Then it shows me the following screen, but it doesn't fill either and reboots again around that same advance:


And finally, it shows me this other screen:


The only thing I can do is try to install it again, but it is an endless cycle of installation attempts that never ends. Does someone know what to do in this case?

I already enabled the SVM inside my BIOS, and I'm using:

• Windows 10 Pro
• AMD Ryzen 9 9950X 16-Core Processor 4.30 GHz
• 96 GB RAM
• MOB MSI MPG X870E Carbon WiFi
• NVIDIA GeForce RTX 4080
• SSD SSD Kingston Fury Renegade 2 TB (Kingston SFYRD2000G)
• HHD 3.6 TB ST4000DM004-2CV104

I already tried other internet guides, but got worse problems: infinite reboots during installation, until I got an error screen. On those other guides, I needed to modify the macOS.vmx file and add some lines to be able to start the installation, but as this guide said, when trying this guide, I started from zero, uninstalling the unlocker by using the file win-uninstall.cmd with admin privileges, deleting the previous VMware Workstation, and installing again with the link of this guide, and using the Unlocker provided inside this guide.


Extras:

• I did point 8 about adding:
  • bcdedit /set hypervisorlaunchtype off
  • reg add "HKLM\SYSTEM\CurrentControlSet\Control\DeviceGuard\Scenarios\HypervisorEnforcedCodeIntegrity” /v “Enabled” /t REG_DWORD /d 0 /f
• I have tried four different ISOs (including the Sonoma one you put in this guide), but I still get the same issue with any of them.
• I used the OPENCORE 16-core setup provided in this post and set the Hard Disk to SATA 0:0.
• The CD/DVD is on SATA 0:1.
• The Hard Disk 2 is on SATA 0:2.
• The lines inside my nacOS.vmx file were okay with a 16 as value.
  • numvcpus = "16"
  • cpuid.coresPerSocket = "16"

Hello. Try to create a virtual machine from the very beginning and use it specifically for 4 core AMD.

This version only works with Ryzen processors with 4 cores or more
Download New Version of VMWare disk image file Here: OPENCORE 1.0.4 - 4 cores

Thanks for your answer. Unfortunately, even doing what you said, I got the same problem.

I captured these screens. I don't know if they could help solve or find the problem:


It's always the same situation.

1. I start installing, but this screen never fills the charge bar; it constantly reboots at this same point:


2. I got the screen with all those white letters that I showed at the beginning.

3. I got the following screen, but without doing anything or selecting the third option, it continues.


4. I got stuck again on a load bar, but this time at the following screen, and again, it never passes that point.


5. Again, point two, the screen with all those white letters that I showed at the beginning.

6. Again, point 3, and it's an infinite cycle.

VMWare Workstation Pro 25.0.0.24995812, macOS Tahoe Beta (25B5072a) handmade iso from official InstallAssistant, macOS_Opencore_Tahoe_1.0.5_8_cores from this topic. A bit luggish but fun to work with.

Good news!!!
Tahoe is now working on VMWare!!!

I finally got Tahoe working on VMWare, and if you want to download and test it too, here are the necessary files:

Thank you very much! This just worked on my Ryzen 7-8700G with the latest 26.1 Tahoe iso (from macplanete.com) ! Definitely need the "Tahoe" Opencore vmdk to boot properly.

Hello! First post Here!

Just wanted to tell everyone how I fixed no internet in Tahoe VM on VMware:

1. Install the vmware tools from reddit (no more avaiable downloads on the website, my version is Darwin 13.0);
2: Boot the vm, the opened Virtual Network Editor from Edit tab;
3: Press on edit settings, VMnet0 finally appears;
4: Select Bridged, Bridged to: "yourinternetcard PCIe GBE", then press apply!

Hope this is helpful for someone, I actually don't know how to use wifi because I'm on a ethernet-only setup. If you have problems it might help to check with WIN+R, ncpa.cpl,
select VMnet1 and VMnet8 and allow WMware bridging protocol by opening the Proprieties tab.

(sorry for my bad english, it's not my first lang).

A gray screen after install about 5 minutes and restart.
And so on.
Strangely.
Since the same virtual machine I put this OS and everything was fine. The same canonicalization on settings and paths.

I forgot about the VMware patch and upgraded to workstation pro 252H and it broke the VM. I had to uninstall and reinstall Workstation Pro 17.6.3 and was able to recover.

FYI just in case you are considering an upgrade.
