[https://github.com/kholia/OSX-KVM OSX-KVM] allows to run macOS on Linux machines.

~~Use the following <code>shell.nix</code> to get all the tools required to boot OSX-KVM:~~

== Installation ==

~~<syntaxHighlight lang=nix>~~

Enable virtualisation support in your system configuration by adding following lines

~~with import <nixpkgs> {};~~

~~mkShell {~~

~~buildInputs = [~~

~~qemu~~

~~python3~~

~~iproute2~~

];

}

~~</syntaxHighlight>~~

~~On NixOS also add the~~ following lines ~~to your <code>configuration.nix</code>:~~

{

~~# this is needed to get a bridge with DHCP enabled~~

virtualisation.libvirtd.enable = true;

~~# Replace <youruser> with your actual username.~~

users.extraUsers.youruser.extraGroups = [ "libvirtd" ];

users.extraUsers.<youruser>.extraGroups = [ "libvirtd" ];

~~# reboot your computer after adding those lines~~

boot.extraModprobeConfig = ''

options kvm_intel nested=1

~~After using cloning the repository use~~ <code>~~./fetch-macOS.py~~</code> ~~as described in~~ the ~~README~~

Replace <code>youruser</code> with the user name of your running system. After applying the configuration, reboot your system so the changes to the kernel modules can take effect.

to ~~download macOS~~

~~Than do:~~

~~<syntaxHighlight lang~~=~~console>~~

== Usage ==

~~$ qemu~~-~~img convert BaseSystem~~.~~dmg -O raw BaseSystem~~.~~img~~

~~</syntaxHighlight>~~

{{Note|This instruction uses a custom fork of OSX-KVM with Nix Flake support. Hopefully these changes will soon be merged to the upstream repository.}}

to ~~create the base image containing the macOS installer, followed by creating~~

Git clone the project repository and run <code>nix run</code> to prepare and run your MacOS system

your ~~actual disk image where later the macOS will be installed to:~~

~~$ qemu~~-~~img create~~ -~~f qcow2 mac_hdd_ng~~.~~img 128G~~

git clone -b flake https://github.com/onny/OSX-KVM.git

cd OSX-KVM

nix run

</syntaxHighlight>

~~Last but not least configure a tap interface that will be used~~ in ~~macOS for networking:~~

You may also want to adjust the cpu count/memory in <code>./OpenCore-Boot.sh</code> if your systems resources allow it.

~~<syntaxHighlight lang=console>~~

On the first run, from the boot menu, select disk utilities and erase / format the Qemu disk that will be used for installation. Then choose the installer from the boot menu. Select the previously created disk image as install target.

~~$ sudo ip tuntap add dev tap0 mode tap~~

~~$ sudo ip link set tap0 up promisc on~~

On the next boot you will a new boot entry containing the actual installation.

~~$ sudo ip link set dev virbr0 up~~

~~$ sudo ip link set dev tap0 master virbr0~~

~~</syntaxHighlight>~~

~~Than boot the system with:~~
