FAQ 💬

How do I use it?

Very simple! These are the steps:

Start the container and connect to port 8006 using your web browser.
Choose Disk Utility and then select the largest Apple Inc. VirtIO Block Media disk.
Click the Erase button to format the disk, and give it any recognizable name you like.
Close the current window and proceed the installation by clicking Reinstall macOS.
When prompted where you want to install it, select the disk you just created previously.
After all files are copied, select your region, language, and account settings.

Enjoy your brand new machine, and don't forget to star this repo!

How do I select the macOS version?

By default, macOS 13 (Ventura) will be installed, as it offers the best performance.

But you can add the VERSION environment variable to your compose file, in order to specify an alternative macOS version to be downloaded:

environment:
  VERSION: "13"

Select from the values below:

Value	Version	Name
`15`	macOS 15	Sequoia
`14`	macOS 14	Sonoma
`13`	macOS 13	Ventura
`12`	macOS 12	Monterey
`11`	macOS 11	Big Sur

How do I change the storage location?

To change the storage location, include the following bind mount in your compose file:

volumes:
  - /var/osx:/storage

Replace the example path /var/osx with the desired storage folder.

How do I change the size of the disk?

To expand the default size of 64 GB, add the DISK_SIZE setting to your compose file and set it to your preferred capacity:

environment:
  DISK_SIZE: "256G"

Tip

This can also be used to resize the existing disk to a larger capacity without any data loss.

How do I change the amount of CPU or RAM?

By default, the container will be allowed to use a maximum of 2 CPU cores and 4 GB of RAM.

If you want to adjust this, you can specify the desired amount using the following environment variables:

environment:
  RAM_SIZE: "8G"
  CPU_CORES: "4"

How do I pass-through a USB device?

To pass-through a USB device, first lookup its vendor and product id via the lsusb command, then add them to your compose file like this:

environment:
  ARGUMENTS: "-device usb-host,vendorid=0x1234,productid=0x1234"
devices:
  - /dev/bus/usb

How do I verify if my system supports KVM?

Only Linux and Windows 11 support KVM virtualization, macOS and Windows 10 do not unfortunately.

You can run the following commands in Linux to check your system:

sudo apt install cpu-checker
sudo kvm-ok

If you receive an error from kvm-ok indicating that KVM cannot be used, please check whether:

the virtualization extensions (Intel VT-x or AMD SVM) are enabled in your BIOS.
you enabled "nested virtualization" if you are running the container inside a virtual machine.
you are not using a cloud provider, as most of them do not allow nested virtualization for their VPS's.

If you do not receive any error from kvm-ok but the container still complains about KVM, please check whether:

you are not using "Docker Desktop for Linux" as it does not support KVM, instead make use of Docker Engine directly.
it could help to add privileged: true to your compose file (or sudo to your docker run command), to rule out any permission issue.

How do I run Windows in a container?

You can use dockur/windows for that. It shares many of the same features, and even has completely automatic installation.

Is this project legal?

Yes, this project contains only open-source code and does not distribute any copyrighted material. Neither does it try to circumvent any copyright protection measures. So under all applicable laws, this project will be considered legal.

However, by installing Apple's macOS, you must accept their end-user license agreement, which does not permit installation on non-official hardware. So only run this container on hardware sold by Apple, as any other use will be a violation of their terms and conditions.
