License violations[edit | edit source]

According to the macOS and OS X software license agreement[1], macOS should only be installed on Apple Mac devices. Neither the editors of this book nor Wikibooks have any liability over the installation of macOS or OS X guests on VirtualBox or any other violations of the software license.

This is against the EULA of Apple, and therefore following this article IS considered a violation of Apple's terms of service.

Installation script[edit | edit source]

The following installation script:

  • free and open-source
  • ...requires only VirtualBox with its Extension Pack and dependencies that can be easily installed in a single command with most open-source package managers
  • ...downloads macOS Catalina, Mojave and High Sierra directly from Apple's servers
  • ...installs macOS without modifying the original Apple binaries and without third-party bootloaders
  • ...creates a VM that is compatible with OpenCore and can be exported (with manual modifications) to KVM/QEMU for near-native performance
  • ...runs on Linux, Windows (WSL, Cygwin), and macOS - Push-button installer of macOS on VirtualBox

Manual installation[edit | edit source]

The manual installation requires access to the Mac App Store through an existing installation of macOS.

Create ISO Installation Media[edit | edit source]

  1. Download the macOS Installer file from the App Store[2] (OS X El Capitan and Sierra is downloadable from Apple's website).
  2. When download finishes, find the app, right-click and select "Show Package Contents".
  3. Inside the sub-folder Contents/SharedSupport you will find a InstallESD.dmg file.
  4. Open "Disk Utility"
  5. Choose Images > Convert
  6. In the window, choose the InstallESD.dmg to convert and the disk type to be "DVD/CD-R master for export". Also choose the name for installer disk and the final destination. Then click "Convert".
  7. After conversion completes, you will see a .cdr file in your destination folder.
  8. Open "Terminal"
  9. Enter hdiutil convert -format UDTO -o /Your/Path/To/macOSInstaller.iso /Your/Path/To/YourCdrFile.cdr
  10. Check destination folder. This is your file for installation in VirtualBox. There should be a .iso file extension.

Installation in VirtualBox[edit | edit source]

  1. Open VirtualBox. Click "new"
  2. Type the name for virtual machine and Mac OS X for type. Choose your version (if you have Mojave or Catalina, choose Mac OS X (64 bit)).
  3. Select memory size.
  4. Select "Create Virtual Disk Now"
  5. Choose VDI for format.
  6. Select storage name and size. The size should be at least 32 GB.
  7. Go to "Settings"
  8. Go to "Storage" Tab

  13. Quit "Settings"
  14. Boot by clicking "Start".
  15. When it boots, you will see some data being displayed.
  16. This part needs clarification - UEFI Interactive Shell loads, but nothing happens. If you use the command "exit" you can shift to the EFI menu, but changing the settings doesn't seem to affect the progress of the UEFI Interactive Shell, which stops at the Shell> prompt.
  17. After a while, you will need to choose the language for installation. Choose your own language.
  18. Then you will be asked where to install macOS.
  19. On the upper-left corner, you will see a "Utilities" button. Click it and select "Disk Utility".

  23. Wait for the process to complete. Then quit Disk Utility.
  24. You will find a new storage media, which is like a hard disk. Choose that storage for the installation of OS X to install.
  25. After installation completes, the virtual machine will automatically shut down. Go to "Settings".
  26. Go to the "Storage" section to eject the .iso file.
  27. Boot virtual machine again.
