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.
Looking for Big Sur
support? See these notes.
Working with Proxmox
and macOS? See Nick's blog for sure.
Yes, we support offline macOS installations now 🎉
This project can always use your help, time and attention. I am looking for help (pull-requests!) with the following work items:
Create full installation (ISO) image without requiring an existing macOS physical/virtual installation.
Documentation around running macOS on popular cloud providers (Hetzner, GCP,
AWS). See the Is This Legal?
section and associated references.
Test accel=hvf
flag on QEMU + macOS Mojave on MacBook Pro.
Document (share) how you use this project to build + test open-source projects / get your stuff done.
Document how to use this project for iOS development.
Document how to use this project for XNU kernel debugging and development.
Document the process to create and reuse VM snapshots. Instantaneous macOS boots would be nice this way.
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.
Better support + docs for AMD Ryzen.
Robustness improvements are always welcome!
(Not so) crazy idea - automate the macOS installation via OpenCV.
A modern Linux distribution. E.g. Ubuntu 20.04 LTS 64-bit or later.
QEMU >= 4.2.0
A CPU with Intel VT-x / AMD SVM support is required
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. AMD FX-8350 works but Phenom II X3 720 does not. Ryzen processors work just fine.
KVM may need the following tweak on the host machine to work.
# echo 1 > /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
Install QEMU and other packages.
sudo apt-get install qemu uml-utilities virt-manager git wget libguestfs-tools -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 https://github.com/kholia/OSX-KVM.git
cd OSX-KVM
Fetch macOS installer.
./fetch-macOS.py
You can choose your desired macOS version here. After executing this step,
you should have the BaseSystem.dmg
file in the current folder.
Sample run:
$ ./fetch-macOS.py
# ProductID Version Post Date Title
1 061-26578 10.14.5 2019-10-14 macOS Mojave
2 061-26589 10.14.6 2019-10-14 macOS Mojave
3 041-91758 10.13.6 2019-10-19 macOS High Sierra
4 041-88800 10.14.4 2019-10-23 macOS Mojave
5 041-90855 10.13.5 2019-10-23 Install macOS High Sierra Beta
6 061-86291 10.15.3 2020-03-23 macOS Catalina
7 001-04366 10.15.4 2020-05-04 macOS Catalina
8 001-15219 10.15.5 2020-06-15 macOS Catalina
9 001-36735 10.15.6 2020-08-06 macOS Catalina

11 001-51042 10.15.7 2020-09-24 macOS Catalina
Choose a product to download (1-11): 11
Attention: Modern NVIDIA GPUs are supported on HighSierra but not on later versions (yet).
Next, convert this file into a usable format.
qemu-img convert BaseSystem.dmg -O raw BaseSystem.img
Create a virtual HDD image where macOS will be installed. If you change the
name of the disk image from mac_hdd.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 128G
NOTE: Create this HDD image file on a fast SSD/NVMe disk for best results.
Now you are ready to install macOS 🚀
CLI method (primary). Just run the OpenCore-Boot.sh
script to start the
installation proces.
./OpenCore-Boot.sh
Note: This same script works for Big Sur, Catalina, Mojave, and High Sierra.
If you are new to installing macOS, see the older README for help.
You are all set! 🙌
(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
for CHANGEME
strings in that file). The following command should do the
trick usually.
sed -i "s/CHANGEME/$USER/g" macOS-libvirt-Catalina.xml
virt-xml-validate macOS-libvirt-Catalina.xml
Create a VM by running the following command.
virsh --connect qemu:///system define macOS-libvirt-Catalina.xml
Launch virt-manager
and start the macOS
virtual machine.
Note: You may need to run sudo ip link delete tap0
command before
virt-manager
is able to start the macOS
VM.
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.
Specifically, we are looking for an AMD RX 560 GPU for testing purposes.
It is possible to have 'beyond-native-apple-hw' performance but it does require work, patience, and a bit of luck (perhaps?).
See networking notes to setup guest networking.
I have the following commands present in /etc/rc.local
.
#!/usr/bin/env bash
sudo ip tuntap add dev tap0 mode tap
sudo ip link set tap0 up promisc on
sudo ip link set dev virbr0 up
sudo ip link set dev tap0 master virbr0
This has been enough for me so far.
Note: You may need to enable the rc.local
functionality manually on modern Ubuntu versions.
To get sound on your virtual Mac, see the "Virtual Sound Device" in notes.
To passthrough GPUs and other devices, see these notes.

To generate your own SMBIOS, use GenSMBIOS.
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.
Gabriel Somlo also has some thoughts on the legal aspects involved in running macOS under QEMU/KVM.
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.
Backstory: I was a (poor) student in Canada once and Apple made my work on cracking Apple Keychains a lot harder than it needed to be.
