macOS in a Docker Container


Run Mac in a Docker container! Run near native OSX-KVM in Docker! X11 Forwarding!

Docker Hub:

docker pull sickcodes/docker-osx

docker run --privileged -v /tmp/.X11-unix:/tmp/.X11-unix sickcodes/docker-osx

# press ctrl G if your mouse gets stuck

Requirements KVM on the host

Need to turn on hardware virtualization in your BIOS, very easy to do.

Then have QEMU on the host if you haven't already:

sudo pacman -S qemu libvirt dnsmasq virt-manager bridge-utils flex bison ebtables edk2-ovmf

sudo apt install qemu qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager

sudo yum install libvirt qemu-kvm -y

# then run
sudo systemctl enable libvirtd.service
sudo systemctl enable virtlogd.service
sudo modprobe kvm

# reboot

Start the same container later (persistent disk)

# look at it
docker ps --all --filter "ancestor=docker-osx"

# boot my old one
docker start $(docker ps -q --all --filter "ancestor=docker-osx")

Additional Boot Instructions

# Boot the macOS Base System

# Click Disk Utility

# Erase the biggest disk

# Partition that disk and subtract 1GB and press Apply

# Click Reinstall macOS

Docker install

If you don't have Docker already

### Arch (pacman version isn't right at time of writing)

tar -xzvf docker-*.tgz
sudo cp docker/* /usr/bin/
sudo dockerd &
sudo groupadd docker
sudo usermod -aG docker $USER
# run docker later
sudo nohup dockerd &

### Ubuntu

apt-get remove docker docker-engine containerd runc -y
apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common -y
curl -fsSL |  apt-key add -
apt-key fingerprint 0EBFCD88
add-apt-repository "deb [arch=amd64] $(lsb_release -cs) stable"
apt-get update -y
apt-get install docker-ce docker-ce-cli -y

Backup the disk

your image will be stored in:


# find your container's root folder

docker inspect $(docker ps -q --all --filter "ancestor=docker-osx") | grep UpperDir

# In the folder from the above command, your image is inside ./home/arch/OSX-KVM/mac_hdd_ng.img

# then sudo cp it somewhere. Don't do it while the container is running tho, it bugs out.

Wipe old images

# WARNING deletes all old images, but saves disk space if you make too many containers

docker system prune --all
docker image prune --all

Instant OSX-KVM in a BOX!

This Dockerfile automates the installation of OSX-KVM inside a docker container.

It will build a 32GB Mojave Disk.

You can change the size and version using build arguments (see below).

This file builds on top of the work done by Dhiru Kholia and many others on the OSX-KVM project.

Custom Build

docker build -t docker-osx:latest \
--build-arg VERSION=10.14.6 \
--build-arg SIZE=200G

docker run --privileged -v /tmp/.X11-unix:/tmp/.X11-unix docker-osx:latest


# persistent disk with least amount of pre-build errands.
