UPDATE: Back in August 2020 I showed you how to install macOS Big Sur with OpenCore on Linux. Back then Big Sur was in beta and you had to take some extra steps to install it. Now, that Big Sur is out of beta, the installation process was simplified and I’ve decided to create a new tutorial instead of editing the old one, to avoid any confusion. Let’s get started…
If you’re running a Linux distro as your daily driver, you can still other distros and OS’. You can even enjoy macOS. You can run Catalina using the clover bootloader and you can even install macOS in a Docker container.
To do this run 7z e -txar InstallAssistant.pkg '.dmg' This should give you the SharedSupport.dmg file. You’ll need to extract Basesystem.dmg from SharedSupport.dmg. First run 7z e -tdmg SharedSupport.dmg 5.hfs. Next create a folder called stuff with mkdir stuff and mount the hfs filesystem to the stuff folder with sudo mount -oloop. 7z x test.zip -aoa 7z: use the 7-zip executable x: use the extract command test.zip: extract files from this archive -aoa: overwrite all existing files Multiple files. To add many files to one archive, please use the 'a' command and the wildcard. symbol. Jul 16, 2017 I was late to the CC party and experienced this as the built in Archive Utility in macOS can’t handle 7z files. The best tool I have found to extract 7z and rar files is The Unarchiver and you can download it straight from the Mac App Store here. It’s really simple to use as it sets itself up as the default unarchiver on your Mac so once.
Today we’re going to take a look at how set up a simple macOS Big Sur VM in QEMU, accelerated by KVM.

REQUIREMENTS
- A modern Linux distribution
- QEMU > 2.11.1
- 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
- Internet access for the installation process
INSTALL QEMU & OTHER REQUIRED PACKAGES
Open the terminal and run:
sudo apt install qemu uml-utilities virt-manager dmg2img git wget libguestfs-tools p7zip
NOTE: Adjust install command and, possibly, packages names according to your distro.
INSTALL macOS Big Sur
1. Open the terminal and run
git clone --depth 1 https://github.com/kholia/OSX-KVM.git macOS-Big-Sur
. When you’re done cloning the git repo, cd into path with cd macOS-Big-Sur
2. Download macOS Big Sur installer from Apple with
./fetch-macOS.py
.NOTE: Here you can choose which macOS you want to install. We will install Big Sur.
When the download is done, you should have
InstallAssistan.pkg
in your folder.3. Now we need to unpack the downloaded
InstallAssistan.pkg
. To do this run 7z e -txar InstallAssistant.pkg '*.dmg'
This should give you the
SharedSupport.dmg
fileUpgrade from lion 10.7.5 to yosemite. 4. You’ll need to extract
Basesystem.dmg
from SharedSupport.dmg
. First run 7z e -tdmg SharedSupport.dmg 5.hfs
Next create a folder called stuff with
mkdir stuff
and mount the hfs filesystem to the stuff folder with sudo mount -oloop *.hfs stuff
Inside the
stuff/com_apple_MobileAsset_MacSoftwareUpdate
folder, there’s a .zip file.Run
7z l stuff/com_apple_MobileAsset_MacSoftwareUpdate/*.zip
to list the contents of the .zip file with and you will see it contains the Basesystem.dmg
that we need.5. Copy the .zip file to your Desktop with
cp stuff/*MacSoftwareUpdate/*.zip ~/Desktop
Extract
Basesystem.dmg
located inside the zip file on your Desktop > AssetData > RestoreNow move the
Basesystem.dmg
back to your macOS Big Sur folder and you can unmount the stuff folder created earlier with sudo umount stuff
.6. Convert
BaseSystem.dmg
to BaseSystem.img
with qemu-img convert BaseSystem.dmg -O raw BaseSystem.img
7. Create a virtual HDD image where macOS will be installed. Run
qemu-img create -f qcow2 mac_hdd_ng.img 128G
NOTE: You can change the size of the virtual drive. 128 GB is just an example. Also if, for any reason, you want to change the name of the disk image from
mac_hdd.img
to something else, you’ll also have to update OpenCore-BS.sh
to point to the new image name.8. Now we can start the installation. But before we do, let’s edit the
OpenCore-Boot.sh
and add more RAM ( by default it’s set to use 3 gigs of RAM ). 8 gigs should be enough. At least Apple seems to think so.You can do that with your favorite GUI text editor or from the terminal with nano, micro or vim. El capitan update 10.12 patch notes.
9. Now you can start the installation process. Run
./OpenCore-BS.sh
.Macos Open 7z
10. You’ll be greeted by this screen. Choose
macOS Base System
10. First thing you’ll need to do is run Disk Utility and format your virtual drive.
11. Exit Disk Utility, choose Reinstall macOS and go through the usual installation steps.
12. During the installation process, your virtual machine will restart and will boot back up. When it does, choose macOS Installer to continue the installation.
13. After a loong time of installing, you will eventually be able to boot into your macOS installation.
You will be greeted with the welcome screen where you can set up your account and settings.

Don’t expect this to run just like a Mac. It’s a VM afterall. And it will feel sluggish mainly because there’s a lack of hardware acceleration. This can only be fixed by passing through a graphics card to the VM. To learn how to do that and other tips, and troubleshooting check out the official project on Github.
