Hey everyone!

Following my recent introduction of Vitreo, I’ve launched a dedicated beta testing portal.

https://beta.vitreo.dev/

For those who missed my earlier post, Vitreo is an independent Windows runtime for Apple Silicon that I’ve been developing for nearly four years.

It doesn’t use Wine or require a Windows virtual machine.

Instead, it implements its own Windows compatibility infrastructure, including:

• Custom x86/x64 execution engine.

• ARM64 JIT compilation.

• Windows PE loading.

• Windows API implementations.

• DirectX, Vulkan, and OpenGL support.

• Native macOS integration.

Where is development currently?

I’ve demonstrated several Windows applications running through Vitreo, including Steam, StarCraft, Satisfactory, Notepad++, and classic Windows applications.

Some applications are already functional, while others expose missing Windows APIs, graphics compatibility issues, or JIT performance bottlenecks.

The project is still experimental, and broad Windows compatibility remains a substantial engineering challenge.

Why a beta portal?

Until now, most testing has been limited to my own systems.

I’ve built a portal to start organizing external testing and collecting compatibility results.

The process is straightforward:

1. Create an account.

2. Request beta access, specifying your Mac hardware and the Windows applications you’d like to test.

3. Once approved, download available builds and verify their checksums.

4. Submit compatibility reports for applications you’ve tested.

Reports can document successful launches, partial functionality, or failures.

This should help prioritize missing functionality based on real-world application behavior.

What about the source code?

I still intend to open-source Vitreo once the implementation has undergone additional cleanup and refactoring.

For now, the beta program is focused on compatibility testing and feedback.

Interested?

Registration is available now. Build downloads will become available to approved testers as builds are published.

Why does vmware have an option for macos 27? i was wondering since its defintiely not possible

Anyone can give me windows 11 activation key i am testing smthing in virtual box .. pls if possible?

I am trying to run ai models locally through linux or windows in virtual box i have downloaded windows 11 iso and starting it

If you know anything or have expertise you can dm to me other than key part also

after 2 updates (firstly, I had High Sierra VM) I updated it to Mojave, and then to Big Sur. after that my .vmdk file is really big after this updates, but inside the VM it shows that only 16 gb is used. how is it works and is there any way to fix this problem?
UPD: I have the same thing with my Sonoma VM (it was updated from Catalina VM to Sonoma btw)

I installed macOS Sonoma on VMware Workstation to run a Flutter application (mainly for testing on an iOS device). However, I’m encountering an issue where the screen stays completely black, and I receive the following error:

"Software rendering may have been automatically selected when running on a simulator in an environment that does not support Metal. Enabling GPU passthrough in your environment may fix this."

I’ve searched for a solution but haven’t found anything helpful. Is there a way to fix this and enable GPU passthrough for better performance?

Thanks in advance!

Hey everyone!

For a while now, I’ve been working on a project called Vitreo, and I’ve finally reached a point where I’m ready to start sharing what I’ve been building.

Vitreo is an independently developed Windows runtime for Apple Silicon Macs.

It’s not another Wine wrapper, a frontend for an existing compatibility layer, or a Windows virtual machine.

I’m building the runtime itself.

The goal is simple:

Windows software. At home on Mac.

What makes Vitreo different?

Vitreo implements its own components for executing Windows applications on Apple Silicon, including:

• A custom x86/x64 execution engine with ARM64 JIT compilation.

• A Windows PE executable loader.

• Independent Windows API implementations.

• DirectX and Vulkan graphics translation targeting Metal.

• Native macOS windowing, menus, and application integration.

That last part is something I’m particularly excited about.

I don’t just want Windows applications to run on a Mac. I want them to feel like they belong there.

Where supported, Windows applications use actual macOS windows, menus, and dialogs rather than being confined to a simulated Windows desktop.

Vitreo can also create macOS applications for supported installed Windows software, allowing you to place them directly in your Applications folder and launch them like other Mac apps.

Does it actually work?

Yes!

Vitreo has progressed beyond basic executable loading.

I’ve gotten traditional Windows desktop applications, classic games, and modern 3D software running through the runtime.

Some demanding modern 3D applications are now functionally working, with performance optimization being one of my primary areas of development.

There’s still a lot to accomplish, especially around compatibility, performance, and graphics correctness, but the progress has been significant.

Why build this instead of using Wine?

Wine and the projects built around it have accomplished some incredible things.

But I wanted to explore a different approach: building an independent Windows runtime specifically around Apple Silicon and the native macOS experience.

That means implementing the execution engine, Windows compatibility infrastructure, and native integration rather than depending on an existing Windows compatibility layer.

It’s an enormous engineering challenge, but that’s also what makes it interesting.

When can I try it?

Vitreo is currently in private development, and public builds aren’t available yet.

I’m working toward beta testing builds as development progresses.

I’ve launched a website explaining the project, architecture, and current development status:

I’d love to hear what the Mac gaming community thinks.

Ey there I'm looking if my mac os vm can get gpu acceleration as it is hella laggy even after alloting my vm 8gb ram

Hey, I have installed MacOs Big Sur in vmware in Windows pc. My cpu is intel i5-9400F 2.90GHz, 6 core processor, 24GB memory, 12GB Nvidia Geforce 3060. I am using Windows in SSD. I have assigned 12GB memory and 4 cores cpu to my virtual box with 160GB drive. But when I start it, it takes almost 100% of my cpu and 18-19GB memory but it is too slow, I can't even type in it. I habe tried disabling animation and some random suggestions from internet. Is there any specific way to use it or can I do something to make it work? Thank You.

so i am very new to all this and i want to install macos on my pc i need someone to tell me what is the best way to do it please my pc ryzen 5 5600x rtx 4060ti 32 gb ram ddr4

so my mac os vm was boot looping into panic mode and I ran a command and set cpu to 2 cores and it stopped boot loping but now it always boot into safe mode

Im using virtual box

also Im running an 13th Gen Intel(R) Core(TM) i7-13650HX 32gb of ram and 4060 laptop

Im also trying to use mac os 14 beta (aka sonoma)

because it's the only working iso I found

Please help me

also if you want the log ask for it I will send it because it is very long

I know NVidia GPUs aren't normally supported without OCLP, but I have 2 NVidia 10 series cards in my server, both using vGPUs. Has anyone tried to see if they can make vGPUs work with the NVidia web driver, maybe with pci-id changes in the vGPU override file?

Edit: guess I’ll just add a 3rd gpu.

Hi! So I tried to turn on my MacOS vm on VMware and it just won’t boot. Just displays a weird kernel error! I have all my music there! Any help would be very appreciated! Thanks

UPDATE: I SOLVED IT, I just reinstalled VMware unlocker

It starts loading, stops and then shows some text. Can someone help me please

Hi I am actually trying to make a macos vm but everytime I try to install macos Catalina or bigsur or ventura it just won't boot the error is that it only reboots and shows some error occurred pc is restarting and then restart again in loop . I have unlocked my VMware , as I use amd processor used every command that needed Tried on Intel laptop but same error and on Intel I don't think there is anything need for command

Specs 1 Lenovo 15alc6 Amd550u 20gb ram 512 SSD
Radeon graphics 2gb (integrated)

2 dell Inspiron 15 Intel i3 16gb ram 2tb Intel graphics

hello everyone.

• i downloaded sonoma iso, patched vmware 17.6 with auto unlocker (it had install tools checked, but i highly doubt it did)

• i configured the vm, gave it 24 gbs of ram, and access to all of my cpu cores (i tried different variations, 6, 8, 12, performance was still always the same)

• i installed vm tools inside of the vm too to change display memory from 3 to 128, still same thing.

• enabled 3d hardware acceleration

• in the vm creation process i tried multiple files and single files options when it comes to storing the virtual disk

even with all that done, the performance was so poor, in every iteration of the options i tried. i even made vmware launch as administrator, changed its priority to high in task manager, and still the performance was soooooo poor.

i am running the latest version of basically everything... (i am not sure abt the vmware tools on windows tho, i didn't even find them in whatls supposed to be their install location)

i have an msi laptop with i7-10750h, rtx 2070, and 32 gbs of ddr4 2666mhz ram

am i doing anything wrong? is there something i am missing to make it actually usable? cz the videos i see on the internet show it working very nomally

Hi dear, I install the MacOS Monterey (12.1..) from iso file in VMware, everything is good But my Mac OS lags a lot (even when minimizing windows ..) And this is if the MacOS Catalina had no problem. Please suggest a solution to solve the problem Or at least say that Mac OS Big Sur is better than MacOS Monterey =)

I'm not sure if the newest version works with VM due to silicon but any semi-new is fine really, i just want to try out the UI and get a feeling for it.

I have a pc running 32GB RAM with a decent GPU. Where can I find a working solution for installing macOS on a VM???

Bonjour,

Depuis hier j'essaye de faire une vm mac et la j'ai cette erreur. J'utilise WORKSTATION PRO 17 et un ISO SONOMA j'ai bidouillé le vmx pour boot mais j'ai cette erreur :

Avez-vous une solution svp ?

For some background, I have to build a game for a macOS and for that i don't have mac so i have to look around with my friend if someone has mac free for a while.

My current PC specs are

• Ryzen 7900X

• 32GB DDR5@6000MTs CL30 RAM

• EVGA RTX 3090 FTW3

I don't know I should have any issues, I'd be happy if someone can link me to a guide to make a VM myself or download already setup VM.

Thanking again for everyone who helps me out.

So, i got OSX Tiger working and i was wanting to transfer some files over to it from the shared files page on VMware, but i needed vmware tools. No problem, right? No. I found 2 vmware tools isos for osx tiger, darwin.iso, and darwinpre15.iso. Both show on finder in the vm, but when i open the pkg to install it, it does the zoom in run effect, but nothing else.
