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

[dmzuck]

@dmzuck don't expect too much help with your problem.

You have simply overloaded everyone with information, so much so that they won't know where to start!

huh wdym overloaded, that was my first message here lol
anyways i used the 4 core file and followed all the steps percisely
here's my error

 

[Edhawk]

I was being sarcastic!

You told us nothing about your system, which host OS, vmdk you are using or which version of macOS you are trying to run. So how do you expect anyone to provide a useful response?

If you had followed the instructions correctly/precisely you wouldn't see that OpenCore to macOS installer error.

Go back and check your work, said the teacher!

 

[otayo3415]

Thank you very much ! It worked perfectly for me.

For those who are having trouble installing Tahoe, make sure to follow the instructions in post #1 exactly, using the OpenCore and the image from #578 (be sure to set the number of VM cores to 8)

Dears,

I have joined this forum as this is the very first time in my whole life I have decided to go with AMD platform as I consider modern Intels not viable option anymore.


Through all my Intel years, I have been using VMWare macOS virtual machine without any problems. Stable, pretty fast (though UI was laggy sometimes), generally I never complained.

But now with my brand new Ryzen 7 9850 X3D I have unfortunately learned that it's tricky to run macOS (I knew it needs hacks, but I also needed hacks on my previous Intel to make VMWare run macOS).

Now I have carefully followed pretty much this whole thread, I have set my VMWare macOS Tahoe machine, it has internet connection, it works using OpenCore macOS_Opencore_Tahoe_1.0.5_8_cores.vmdk (provided earlier in this thread). VMWare Tools work, I can resize my VMWare window, the UI is rather smooth, performance is very decent, but I have one very annoying problem I have never ever had on Intel.

It reboots randomly.

No error, no crash, just reboot for no reason. Sometimes I can work there for dozens of minutes without any problems and sometimes it reboots literally every 3-4 minutes, even when there is no activity there from my end.

I was searching the forums here and I couldn't find any similar problems.
Does anyone of you have any knowledge and experience how to solve this somewhat annoying behavior?


Thank you in advance for any tips

Had 2 pc's with the latest 32 bit version of workstation pro running Sequoia, both stable. As an experiment, I updated one of them to Workstation Pro 26h1, which is their first version as 64 bit. Of course it broke the Sequoia vm, and the patch program would not add back the Mac Os line, not surprisingly targeted the 32 bit version. In the past each time I updated VMWare running the patch program restablished the Mac Os line, and then the Mac VM would again function.

Not a big issue, but I wonder if a patch to add back Mac Os to the 64 bit version exists, or is in the works?

Thanks for your help.

Found 26h1 unlocker, my Mac is back running on 26h1. All is well.

 

[Edhawk]

Can you provide a link to the 26H1 unlocker so others don’t have to go searching for it.

I believe this one:

Hi, first of all thanks to the OP and the helpers of this thread.

I've got an Asus Vivobook based on AMD Ryzen 9 5900HX with 8 cores and running VMware Workstation Pro v17.6.3 on Windows 11 Home.

I've trying to install Sonoma & Sequoia since a week ( read the guide multiple times and repeated each step ) but keep getting the following error:



All files were downloaded from the links in the first post. However, I downloaded the MAC ISO from this link:

GitHub - Pyenb/macOS-ISOs: macOS ISOs. Includes torrent download links and MD5 hashes. Created using MIST or by manually converting.

macOS ISOs. Includes torrent download links and MD5 hashes. Created using MIST or by manually converting. - Pyenb/macOS-ISOs

Things I've tried so far which have no helped:

-Downgrading VMware to v15&16
-Tried 4 & 8 cores OC files

I've don't think I've missed anything from the guide, which makes me question if it's even possible to install this on an AMD based laptop?

Thanks for the help in advance!

Any help guys? @tucano2000 @Edhawk

hey guys keep getting stuck here ran so many checks hypervisor V is off too

Check your Network settings, as the last bit of information in the screens image above is related to errors with the Network IP and Ethernet MAC address.

No idea why you are seeing that screen, as we have know idea what system you are using, which VM files you are using or which OS you are trying to install. So it is hardly surprising that no one has responded to your call for help.

The macOS 15.2 works out of box on my new Ryzen 7 8700F!!!

Can develop iphone apps from a 3rd party codes!

Slightly offtopic but this works perfectly with Virtualbox to my surprise (switch USB to XHCI and 128MB VRAM)
Use the same OpenCore VMDKs and run these (tested on 5800H)

cd C:\Program Files\Oracle\VirtualBox
VBoxManage modifyvm "macOS" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
VBoxManage setextradata "macOS" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac19,3"
VBoxManage setextradata "macOS" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
VBoxManage setextradata "macOS" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "VM"
VBoxManage setextradata "macOS" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "vbox(c)AppleComputerInc"
VBoxManage setextradata "macOS" VBoxInternal2/EfiGraphicsResolution 1920x1080
VBoxManage setextradata "macOS" "VBoxInternal/TM/TSCMode" "RealTSCOffset"
VBoxManage modifyvm "macOS" --nictype1 82545EM
VBoxManage modifyvm "macOS" --nic1 nat

The graphics are faster than VMware for some reason.
May need a new topic.

 

[HKPhysicist]

VirtualBox is usually slow.

Ventura

Tahoe crashes randomly unfortunately, despite being faster...

For the best result, I recommend
macOS 15.7.7 and VMWare.
Refer to the earlier posts under this thread to download the boot disk of macOS 15.


It is stable enough to develop iPhone app, but lacks graphic acceleration.

ok i've tried for ohurs on my hp pavillion 15 eh-2085cl, and i've never gotten a single time for it to work, i built it myself using gibmacos and qemu-img, and claude directed me, but i still can't get it to work, i'm trying to get a tahoe copy currently but i cant get it because my catalina won't work, it gives this funky ass error screen and im confused on how to fix it

i got that EXACT same problem too, and i can't seem to fix it either, but instead of using tucano's setup i built my own using gibmacos
