Note
This README.md
documents the process of creating a Virtual Hackintosh
system.
Note: All blobs and resources included in this repository are re-derivable (all instructions are included!).
💚 Looking for commercial support with this stuff? I am available
over email for a chat for commercial support options only. Note: Project sponsors get access to the Private OSX-KVM
repository, and direct support.
Struggling with Content Caching
stuff? We can help.
Working with Proxmox
and macOS? See Nick's blog for sure.
Yes, we support offline macOS installations now - see this document 🎉
Contributing Back
This project can always use your help, time and attention. I am looking for help (pull-requests!) with the following work items:
-
Documentation around running macOS on popular cloud providers (Hetzner, GCP, AWS). See the
Is This Legal?
section and associated references. -
Document (share) how you use this project to build + test open-source projects / get your stuff done.
-
Document how to use this project for XNU kernel debugging and development.
-
Document the process to launch a bunch of headless macOS VMs (build farm).
-
Document usage of munki to deploy software to such a
build farm
. -
Enable VNC + SSH support out of the box or more easily.
-
Robustness improvements are always welcome!
-
(Not so) crazy idea - automate the macOS installation via OpenCV.
Requirements
-
A modern Linux distribution. E.g. Ubuntu 22.04 LTS 64-bit or later.
-
QEMU >= 6.2.0
-
A CPU with Intel VT-x / AMD SVM support is required (
grep -e vmx -e svm /proc/cpuinfo
) -
A CPU with SSE4.1 support is required for >= macOS Sierra
-
A CPU with AVX2 support is required for >= macOS Mojave
Note: Older AMD CPU(s) are known to be problematic but modern AMD Ryzen processors work just fine (even for macOS Sonoma).
Installation Preparation
-
Install QEMU and other packages.
sudo apt-get install qemu uml-utilities virt-manager git \ wget libguestfs-tools p7zip-full make dmg2img tesseract-ocr \ tesseract-ocr-eng genisoimage -y
This step may need to be adapted for your Linux distribution.
-
Clone this repository on your QEMU system. Files from this repository are used in the following steps.
cd ~ git clone --depth 1 --recursive https://github.com/kholia/OSX-KVM.git cd OSX-KVM
Repository updates can be pulled via the following command:
git pull --rebase
This repository uses rebase based workflows heavily.
-
KVM may need the following tweak on the host machine to work.
sudo modprobe kvm; echo 1 | sudo tee /sys/module/kvm/parameters/ignore_msrs
To make this change permanent, you may use the following command.
sudo cp kvm.conf /etc/modprobe.d/kvm.conf # for intel boxes only sudo cp kvm_amd.conf /etc/modprobe.d/kvm.conf # for amd boxes only
-
Add user to the
kvm
andlibvirt
groups (might be needed).sudo usermod -aG kvm $(whoami) sudo usermod -aG libvirt $(whoami) sudo usermod -aG input $(whoami)
Note: Re-login after executing this command.
-
Fetch macOS installer.
./fetch-macOS-v2.py
You can choose your desired macOS version here. After executing this step, you should have the
BaseSystem.dmg
file in the current folder.ATTENTION: Let
>= Big Sur
setup sit at theCountry Selection
screen, and other similar places for a while if things are being slow. The initial macOS setup wizard will eventually succeed.Sample run:
$ ./fetch-macOS-v2.py 1. High Sierra (10.13) 2. Mojave (10.14) 3. Catalina (10.15) 4. Big Sur (11.7) 5. Monterey (12.6) 6. Ventura (13) - RECOMMENDED 7. Sonoma (14) Choose a product to download (1-6): 6
Note: Modern NVIDIA GPUs are supported on HighSierra but not on later versions of macOS.
-
Convert the downloaded
BaseSystem.dmg
file into theBaseSystem.img
file.dmg2img -i BaseSystem.dmg BaseSystem.img
-
Create a virtual HDD image where macOS will be installed. If you change the name of the disk image from
mac_hdd_ng.img
to something else, the boot scripts will need to be updated to point to the new image name.qemu-img create -f qcow2 mac_hdd_ng.img 256G
NOTE: Create this HDD image file on a fast SSD/NVMe disk for best results.
-
Now you are ready to install macOS 🚀
Installation
-
CLI method (primary). Just run the
OpenCore-Boot.sh
script to start the installation process../OpenCore-Boot.sh
Note: This same script works for all recent macOS versions.
-
Use the
Disk Utility
tool within the macOS installer to partition, and format the virtual disk attached to the macOS VM. UseAPFS
(the default) for modern macOS versions. -
Go ahead, and install macOS 🙌
-
(OPTIONAL) Use this macOS VM disk with libvirt (virt-manager / virsh stuff).
-
Edit
macOS-libvirt-Catalina.xml
file and change the various file paths (search forCHANGEME
strings in that file). The following command should do the trick usually.sed "s/CHANGEME/$USER/g" macOS-libvirt-Catalina.xml > macOS.xml virt-xml-validate macOS.xml
-
Create a VM by running the following command.
virsh --connect qemu:///system define macOS.xml
-
If needed, grant necessary permissions to libvirt-qemu user,
sudo setfacl -m u:libvirt-qemu:rx /home/$USER sudo setfacl -R -m u:libvirt-qemu:rx /home/$USER/OSX-KVM
-
Launch
virt-manager
and start themacOS
virtual machine.
-
Headless macOS
-
Use the provided boot-macOS-headless.sh script.
./boot-macOS-headless.sh
Setting Expectations Right
Nice job on setting up a Virtual Hackintosh
system! Such a system can be used
for a variety of purposes (e.g. software builds, testing, reversing work), and
it may be all you need, along with some tweaks documented in this repository.
However, such a system lacks graphical acceleration, a reliable sound sub-system, USB 3 functionality and other similar things. To enable these things, take a look at our notes. We would like to resume our testing and documentation work around this area. Please reach out to us if you are able to fund this area of work.
It is possible to have 'beyond-native-apple-hw' performance but it does require work, patience, and a bit of luck (perhaps?).
Post-Installation
-
See networking notes on how to setup networking in your VM, outbound and also inbound for remote access to your VM via SSH, VNC, etc.
-
To passthrough GPUs and other devices, see these notes.

Is This Legal?
The "secret" Apple OSK string is widely available on the Internet. It is also included in a public court document available here. I am not a lawyer but it seems that Apple's attempt(s) to get the OSK string treated as a trade secret did not work out. Due to these reasons, the OSK string is freely included in this repository.
Please review the 'Legality of Hackintoshing' documentation bits from Dortania's OpenCore Install Guide.
Gabriel Somlo also has some thoughts on the legal aspects involved in running macOS under QEMU/KVM.
You may also find this 'Announcing Amazon EC2 Mac instances for macOS' article interesting.
Note: It is your responsibility to understand, and accept (or not accept) the Apple EULA.
Note: This is not legal advice, so please make the proper assessments yourself and discuss with your lawyers if you have any concerns (Text credit: Dortania)
Motivation
My aim is to enable macOS based educational tasks, builds + testing, kernel debugging, reversing, and macOS security research in an easy, reproducible manner without getting 'invested' in Apple's closed ecosystem (too heavily).
These Virtual Hackintosh
systems are not intended to replace the genuine
physical macOS systems.
Personally speaking, this repository has been a way for me to 'exit' the Apple
ecosystem. It has helped me to test and compare the interoperability of Canon CanoScan LiDE 120
scanner, and Brother HL-2250DN
laser printer. And these
devices now work decently enough on modern versions of Ubuntu (Yay for free
software). Also, a long time back, I had to completely wipe my (then) brand new
MacBook Pro (Retina, 15-inch, Late 2013)
and install Xubuntu on it - as the
OS X
kernel kept crashing on it!
Backstory: I was a (poor) student in Canada in a previous life and Apple made my work on cracking Apple Keychains a lot harder than it needed to be. This is how I got interested in Hackintosh systems.
