A whole computer dedicated to your macOS VMs.

A dedicated operating system, based on Debian 13, that exists only to run OSX-REIMS. It comes as a bootable ISO: you install it to a disk, the first setup prepares the graphics drivers and OSX-REIMS, and from then on the computer boots straight into the macOS VM console.

OSX-REIMS is the same in both cases, and so are the VMs and Reims vGPU. On Ubuntu, you install and maintain the system, the desktop and the drivers, and OSX-REIMS is one application among others.

On vGPU OS, the system is minimal, with no desktop, and takes care of the graphics drivers and the preparation by itself: the whole machine is dedicated to the VMs.

No. vGPU OS is the computer’s system: it replaces whatever is on the chosen disk. You do not need Ubuntu, a desktop or to install drivers by hand.

Not to install and use it. The installer and the first setup ask what they need, and OSX-REIMS comes with a built-in EFI: no knowledge of EFI, OpenCore, Kexts or ACPI is required.

The vGPU OS and OSX-REIMS screens are in English. For diagnostics and rescue there is a Linux console, which is optional.

That is not the idea. vGPU OS takes the whole disk you pick and is not meant for dual boot. Other disks in the computer are not touched, but the recommendation is to dedicate the machine to it.

Not in this release. The first setup and VM creation need internet over a network cable (Ethernet) with DHCP. The installation itself works without internet.

The first setup installs Debian’s drivers for Intel, AMD and NVIDIA GPUs. Tested on real hardware so far: Intel UHD 770 (integrated), AMD Radeon RX 6600 and RX 580.

NVIDIA, Intel Arc and AMD integrated GPUs are compatible with the project too, because they support Vulkan on Linux. The requirement is Vulkan 1.2 or later; results may vary with the GPU model and the driver.

The first setup identifies the card, picks the proprietary driver package from Debian’s non-free archive and asks before installing. CUDA is never installed, and no NVIDIA driver ships inside the ISO.

NVIDIA GPUs are compatible with the project because they support Vulkan on Linux, and they have been tested by the community with OSX-REIMS on other occasions. Cards newer than those supported by Debian 13’s driver are left out.

Yes. In OSX-REIMS, set the VM to start by itself: on power-on, vGPU OS opens the console and the VM starts right after, up to the macOS screen. The "Power on and land in macOS" demo shows that path.

There is no in-place update in this release. A new version is installed from the USB stick, which erases the disk — VMs included. Back up anything important before reinstalling.

It installs and boots, but without a real GPU there is only software rendering, and macOS is far too slow or does not start at all. vGPU OS is made to run directly on the computer.

vGPU OS may only be used while the membership is active. If it is canceled or not renewed, the license to use it ends and vGPU OS must be removed from the computer, along with the OSX-REIMS that comes with it.

To remove it, just install another system over the vGPU OS disk. The VMs live on that same disk: first copy elsewhere any files you created and want to keep.

In the #vgpu-os channel of the Universo Hackintosh Discord server, open to Hackintosh - vGPU OS members: click Gerar meu link de download (Get my download link), in the pinned message of the channel, and the bot replies, visible only to you, with a personal download link. The ISO is not distributed through this website.

The link is valid for a single download, only downloads for your Discord account (the page asks you to sign in) and expires in 10 minutes if unused. After a download starts, a new link can be generated 24 hours later. The full rules and the data recorded are in Download terms and privacy, in the site footer.

No. vGPU OS is an experimental project, for study and testing, and does not replace an Apple computer. Features that depend on Apple hardware, services and integrations may not work or may stop working with any update.

If you need macOS for everyday work, with stability and support, the honest recommendation is to buy a Mac.

No. vGPU OS and OSX-REIMS are Universo Hackintosh projects, independent from Reims vGPU. They are not affiliated with, sponsored or endorsed by the Reims vGPU authors.

Reims vGPU is third-party open-source software: it does not ship in the ISO; OSX-REIMS downloads it from the original repository and builds it on your computer, under its authors’ license.

Yes. vGPU OS is at version 0.1.2, in alpha, and is provided without warranty and without technical support. OSX-REIMS and Reims vGPU are in alpha too. Features and behavior may change between versions.

No. The membership gives access to the ISO and the Discord channels, but it does not include technical support or any guarantee that it will work.

The #vgpu-os-chat channel is a space for members to help each other: you can describe the problem there and share the logs from vgpu-os diagnostics --save for the community to look at. Help is voluntary, and there is no guarantee of a reply, a timeframe or a fix. Support requests by email are not answered.
