base on Run macOS on QEMU/KVM. With OpenCore + Monterey + Ventura + Sonoma support now! Only commercial (paid) support is available now to avoid spammy issues. No Mac system is required. ### 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!).
:green_heart: Looking for **commercial** support with this stuff? I am [available
over email](mailto:
[email protected]?subject=[GitHub]%20OSX-KVM%20Commercial%20Support%20Request&body=Hi%20-%20We%20are%20interested%20in%20purchasing%20commercial%20support%20options%20for%20your%20project.) 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](https://www.nicksherlock.com/).
Yes, we support offline macOS installations now - see [this document](./run_offline.md) 🎉
### 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](https://github.com/munki/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 24.04 LTS 64-bit or later.
* QEMU >= 8.2.2
* 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 Ventura
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-system uml-utilities virt-manager git \
wget libguestfs-tools p7zip-full make dmg2img tesseract-ocr \
tesseract-ocr-eng genisoimage vim net-tools screen -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` and `libvirt` 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 the `Country 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)
8. Sequoia (15)
Choose a product to download (1-8): 6
```
Note: Modern NVIDIA GPUs are supported on HighSierra but not on later
versions of macOS.
* Convert the downloaded `BaseSystem.dmg` file into the `BaseSystem.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. Use `APFS` (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
for `CHANGEME` strings in that file). The following command should do the
trick usually.
```
sed "s/CHANGEME/$USER/g" macOS-libvirt-Catalina.xml > macOS.xml
virt-xml-validate macOS.xml
```
- Create a VM by running the following command.
```bash
virsh --connect qemu:///system define macOS.xml
```
- If needed, grant necessary permissions to libvirt-qemu user,
```
sudo setfacl -m u:libvirt-qemu:rx /home/$USER
sudo setfacl -R -m u:libvirt-qemu:rx /home/$USER/OSX-KVM
```
- Launch `virt-manager` and start the `macOS` virtual machine.
### Headless macOS
- Use the provided [boot-macOS-headless.sh](./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](notes.md). We would like to resume our testing and
documentation work around this area. Please [reach out to us](mailto:
[email protected]?subject=[GitHub]%20OSX-KVM%20Funding%20Support)
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](networking-qemu-kvm-howto.txt) 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](notes.md#gpu-passthrough-notes).
* Need a different resolution? Check out the [notes](notes.md#change-resolution-in-opencore) included in this repository.
* Trouble with iMessage? Check out the [notes](notes.md#trouble-with-imessage) included in this repository.

### 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](http://www.rcfp.org/sites/default/files/docs/20120105_202426_apple_sealing.pdf). 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](https://dortania.github.io/OpenCore-Install-Guide/why-oc.html#legality-of-hackintoshing).
Gabriel Somlo also has [some thoughts](http://www.contrib.andrew.cmu.edu/~somlo/OSXKVM/) on the legal aspects involved in running macOS under QEMU/KVM.
You may also find [this 'Announcing Amazon EC2 Mac instances for macOS' article](https://aws.amazon.com/about-aws/whats-new/2020/11/announcing-amazon-ec2-mac-instances-for-macos/
) 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](https://github.com/openwall/john/blob/bleeding-jumbo/src/keychain_fmt_plug.c) a lot harder than it needed to be. This is how I got interested in Hackintosh systems.
