This post contains the steps I extracted from various resources in order to get a fully working High Sierra install within VirtualBox 5. Step 1: Download The High Sierra Installer. To do this, you need to be on an existing macOS system. I was unable to find the download within the App Store itself, but following this link opened the App Store at the correct page.

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Check compatibility

If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that it's too old to be opened on this version of macOS, or that your Mac doesn't have enough free storage space for the installation.

To confirm compatibility before downloading, check the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also find compatibility information on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.

Make a backup

Before installing, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.

Download macOS

It takes time to download and install macOS, so make sure that you're plugged into AC power and have a reliable internet connection.

Safari uses these links to find the old installers in the App Store. After downloading from the App Store, the installer opens automatically.

  • macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
  • macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
  • macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion

Safari downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.

  • macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion
  • OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard
  • OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion, or Snow Leopard

Install macOS

Follow the onscreen instructions in the installer. It might be easiest to begin installation in the evening so that it can complete overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs macOS and related firmware updates.

You might also be able to use macOS Recovery to reinstall the macOS you're using now, upgrade to the latest compatible macOS, or install the macOS that came with your Mac.

During a recent pentest, I needed to throw together a macOS virtual machine. Although there was lots of guides around the web, none seemed to work from start to finish. This post contains the steps I extracted from various resources in order to get a fully working High Sierra install within VirtualBox 5.

Step 1: Download The High Sierra Installer

To do this, you need to be on an existing macOS system. I was unable to find the download within the App Store itself, but following this link opened the App Store at the correct page: https://itunes.apple.com/us/app/macos-high-sierra/id1246284741?mt=12

After opening the aforementioned page in the App Store, start the download, but cancel the installation when it starts.

You can then verify that the installer has been downloaded by checking that '/Applications/Install macOS High Sierra.app' exists.

Step 2: Create a Bootable ISO

Next, you need to create an ISO from the installer application that was downloaded in step 1.

Running the below commands will create an ISO on your desktop named HighSierra.iso:

Step 3: Creating the Virtual Machine

I experimented with a few different settings in regards to the CPU and RAM allocation. I didn’t find a combination that didn’t work, but create a VM with the following things in mind:

  • Ensure the name of the VM is MacOS (ensure to keep the same casing)
  • Ensure the type is Mac OS X and the version is macOS 10.12 Sierra (64-bit) (there is a High Sierra option too, but I chose Sierra by accident and it worked)
  • Untick Floppy in System > Motherboard > Boot Order
  • Use >= 4096 MB of memory in System > Motherboard
  • Use >= 2 CPUs in System > Processor
  • Use 128 MB of video memory in Display > Screen
  • Optionally enable 3D acceleration in Display > Screen
  • Remove the IDE device in Storage > Storage Devices and replace it with a SATA controller
  • Add a new hard disk device under the SATA controller with >= 60 GB of space
  • Ensure an optical drive is present under the SATA controller and mount the previously created ISO to it
  • Untick the Enable Audio option under Audio

After creating the virtual machine with the above configuration, hit OK and exit the settings screen. Now, a number of extra options need to be set.

If you’re on Windows, you’ll need to cd into the appropriate directory under the VirtualBox installation path to run VBoxManage. For Linux users, this should be in your PATH variable already:

After running the above commands, the VM should be ready to boot!

Step 4: Installation

This is where near enough everything I read stopped, despite there being one more problem in the way - UEFI.

Boot into the VM, go into Disk Utility and erase the virtual disk that you added to the machine.

After erasing the disk, start the installation procedure. After a short amount of time, it will reboot the VM.

Once it reboots, it’s going to boot back off the ISO again, once it’s done this, just shutdown the VM and eject the disk [the ISO] and then start the VM again to boot from disk.

On the next boot, it should boot into the installer that was copied to disk, but instead, you will be presented with a UEFI shell like below:

To continue the macOS installation, follow these steps:

  1. Type exit and hit return
  2. Select Boot Maintenance Manager and hit return
  3. Select Boot From File and hit return
  4. You will see two partitions, select the second partition and hit return
  5. Select macOS Install Data and hit return
  6. Select Locked Files and hit return
  7. Select Boot Files and hit return
  8. Select boot.efi and hit return

After following these steps, you will boot into the remainder of the macOS installation. From here, just follow the steps as per a regular macOS installation.

The next time you boot your virtual machine, you will not have to go through the UEFI shell; it should work without any further problems.

Step 5: Tweaking The Resolution

As there is no VirtualBox additions for macOS, the screen resolution won’t automatically change. If you know what resolution you wish to use, however, you can set it manually.

Ensure the virtual machine is powered off, and then run the following command; replacing 1920x1080 with whatever resolution you would like to use:

After running the above command, the next time you boot the machine, it will use the resolution specified.

Now, you should have a fully working macOS virtual machine!
