Oracle Virtualbox On Mac

In Oracle VM VirtualBox, a virtual machine and its settings are described in a virtual machine settings file in XML format. In addition, most virtual machines have one or more virtual hard disks. These are typically represented by disk images, such as those in VDI format. The location of these files may vary, depending on the host operating system. See Section 3.1.1, “The Machine Folder”.

Global configuration data for Oracle VM VirtualBox is maintained in another location on the host. See Section 3.1.2, “Global Settings”.

By default, each virtual machine has a directory on your host computer where all the files of that machine are stored: the XML settings file, with a .vbox file extension, and its disk images. This is called the machine folder.

You can download Oracle VM VirtualBox for MacBook right here and get the most important virtualization tool in a couple of seconds. VirtualBox has a user-friendly interface and contains all the needed functions in its main menu. Both web developers and users with no additional knowledge can easily start using the app without any difficulties. 2.1 Create MacOS Virtual Machine In Virtualbox. Open virtualbox, click New button to create a new. Install Linux(Ubuntu) on Oracle VirtualBox. Which usually works much better on linux than on Windows or Mac, but you don’t want to leave your preferred os — may be windows or Mac OS or you want to experiment with a new software without risking the host OS. VirtualBox is being actively developed with frequent releases and has an ever growing list of features, supported guest operating systems and platforms it runs on. VirtualBox is a community effort backed by a dedicated company: everyone is encouraged to contribute while Oracle ensures the product always meets professional quality criteria. If Oracle does pledge support for VirtualBox, it is unclear what it will run exactly, x86/64 like Windows 10 or ARM only OSes (for which Microsoft could choose to support M1 – Apple has said it really is up to them). Continue Reading. You unfortunately cannot run VirtualBox on Macs with Apple’s M1 chip.

By default, this machine folder is located in a common folder called VirtualBox VMs, which Oracle VM VirtualBox creates in the current system user's home directory. The location of this home directory depends on the conventions of the host operating system, as follows:

  • On Windows, this is the location returned by the SHGetFolderPath function of the Windows system library Shell32.dll, asking for the user profile. A typical location is C:Usersusername.

  • On Linux, Mac OS X, and Oracle Solaris, this is generally taken from the environment variable $HOME, except for the user root where it is taken from the account database. This is a workaround for the frequent trouble caused by users using Oracle VM VirtualBox in combination with the tool sudo, which by default does not reset the environment variable $HOME.

    A typical location on Linux and Oracle Solaris is /home/username and on Mac OS X is /Users/username.

For simplicity, we abbreviate the location of the home directory as $HOME. Using that convention, the common folder for all virtual machines is $HOME/VirtualBox VMs.

As an example, when you create a virtual machine called 'Example VM', Oracle VM VirtualBox creates the following:

  • A machine folder: $HOME/VirtualBox VMs/Example VM/

  • In the machine folder, a settings file: Example VM.vbox

  • In the machine folder, a virtual disk image: Example VM.vdi.

This is the default layout if you use the Create New Virtual Machine wizard described in Creating Your First Virtual Machine. Once you start working with the VM, additional files are added. Log files are in a subfolder called Logs, and if you have taken snapshots, they are in a Snapshots subfolder. For each VM, you can change the location of its snapshots folder in the VM settings.

You can change the default machine folder by selecting Preferences from the File menu in the Oracle VM VirtualBox main window. Then, in the displayed window, click on the General tab. Alternatively, use the VBoxManage setproperty machinefolder command. See VBoxManage setproperty.

In addition to the files for the virtual machines, Oracle VM VirtualBox maintains global configuration data in the following directory:

  • Linux and Oracle Solaris:$HOME/.config/VirtualBox.

  • Windows:$HOME/.VirtualBox.

  • Mac OS X:$HOME/Library/VirtualBox.

Oracle VM VirtualBox creates this configuration directory automatically, if necessary. You can specify an alternate configuration directory by either setting the VBOX_USER_HOME environment variable, or on Linux or Oracle Solaris by using the standard XDG_CONFIG_HOME variable. Since the global VirtualBox.xml settings file points to all other configuration files, this enables switching between several Oracle VM VirtualBox configurations.

In this configuration directory, Oracle VM VirtualBox stores its global settings file, an XML file called VirtualBox.xml. This file includes global configuration options and a list of registered virtual machines with pointers to their XML settings files.

The following table gives a brief overview of the configuration data locations on an Oracle VM VirtualBox host.

Oracle VM VirtualBox uses XML for both the machine settings files and the global configuration file, VirtualBox.xml.

All Oracle VM VirtualBox XML files are versioned. When a new settings file is created, for example because a new virtual machine is created, Oracle VM VirtualBox automatically uses the settings format of the current Oracle VM VirtualBox version. These files may not be readable if you downgrade to an earlier version of Oracle VM VirtualBox. However, when Oracle VM VirtualBox encounters a settings file from an earlier version, such as after upgrading Oracle VM VirtualBox, it attempts to preserve the settings format as much as possible. It will only silently upgrade the settings format if the current settings cannot be expressed in the old format, for example because you enabled a feature that was not present in an earlier version of Oracle VM VirtualBox.

In such cases, Oracle VM VirtualBox backs up the old settings file in the virtual machine's configuration directory. If you need to go back to the earlier version of Oracle VM VirtualBox, then you will need to manually copy these backup files back.

We intentionally do not document the specifications of the Oracle VM VirtualBox XML files, as we must reserve the right to modify them in the future. We therefore strongly suggest that you do not edit these files manually. Oracle VM VirtualBox provides complete access to its configuration data through its the VBoxManage command line tool, see VBoxManage and its API, see Chapter 4, Oracle VM VirtualBox Programming Interfaces.

Windows, macOS – which one do you want to use today? On a traditional setup, you’re stuck with one or the other. But with virtual box, you actually have macOS on a Windows PC.

It’s the freedom that computer users have enjoyed with Linux and other operating systems.

But Apple has made it difficult to install their operating system on anything other than their own hardware. All of that is changing, and Virtual Box is responsible for it and the rise of the Hackintosh.

New to hackintosh? Learn more about it in our what is hackintosh? overview.

Note: A lot of people will be able to get a mac virtual machine one Windows running smoothly, but sound doesn’t seem to work well. That’s really not an issue because you’ll still be able to access all of your apps and software.

I also recommend that you have access to a real Mac. You might be able to find some distributions of the High Sierra ISO online, but there is always a risk when downloading from an unofficial source. Instead, borrow a Mac from a friend, or use your own and download the High Sierra OS from the App Store.

Everything You Need to Get Started with Installing macOS on VirtualBox

Before we go through the steps on how to install macOS on Virtual Box, let’s get everything together that you’ll need to get started.

  1. Open up your Mac
  2. Go to the App Store
  3. Type in “High Sierra”

You’ll want to search for your desired operating system (we’ll be using High Sierra), and Download it.

Note: You’ll need a decent computer to be able to run Virtual Box. Your computer will need to meet these minimum requirements:

  • Dual core processor
  • 4GB Ram or higher
  • 64-bit

If your computer doesn’t meet these requirements, you won’t be able to run macOS properly. You’ll be able to download VirtualBox from the official website. I’m not going to go through the installation process, as the website will have all of the information you need to be able to install VirtualBox.

I do recommend that you read all of the documentation and ask any questions that you have in the community section of the website.

VirtualBox 6.0 was just released, so it’s definitely a great time to get started with your own macOS.

Extract macOS Sierra

Make sure you’ve downloaded High Sierra, and then you’ll want to run a few commands from your terminal . You’ll be able to open the terminal at: Applications > Utilities > Terminal. Once inside of the terminal, you’ll want to run the following commands:

Go to your desktop and rename the file, removing the “.cdr” extension. You need this extension to read “.iso” for it to work properly.

You’ve successfully created your own ISO file so that you can bootup your macOS.

The next step is to copy the file over to your Windows machine (using a large USB drive seems to work best). This file will be mounted in your virtual machine later on in the article, so it’s very important that this step is completed successfully.

Creating a mac Virtual Machine on Windows

You’ll want to create a virtual machine, and this is really easy. You’ll open up VirtualBox and click New. You’ll want to have the following parameters selected or entered before clicking Next.

  • Name: High Sierra
  • Type: Mac OS X
  • Version: Mac OS X (64-bit)

Pay attention when selecting the version because you may find that High Sierra is offered as a version when you go to install it. But if it’s not, you can just choose the settings I listed above and they should work fine.

You’ll then be proceeding through all of the settings.

When you come up to the RAM setting, you’ll want to be generous. VirtualBox requires a minimum of 4GB or RAM to run, but the more the better.


You’ll want to provide at least 4GB to your macOS, or 4096MB to be precise. A general rule of thumb is that if you can spare it, supply more RAM to your virtual machine. RAM will allow the operating system to put more information into memory and retrieve it faster.

For better overall performance, supply as much RAM as you can.


The next steps are also important, and they’ll include:

  • Hard Disk: Choose the “Create a virtual hard disk now” setting.
    • Choose VDI when choosing the hard disk type.
    • Choose Fixed Size instead of Dynamic for added speed.
    • Set the size of the drive to at least 25GB.

You’ll now have your virtual machine using the RAM and disk space properly, and you’ll have to work your way through a few screen prompts before having everything setup properly.

Configuring Your VirtualBox to Run macOS High Sierra

We’ve made a lot of progress so far, and now it’s time to configure your virtual machine properly. You’ll see in the main window of VirtualBox that “High Sierra” is listed. Click on this and then click on the “Settings” button.

You’ll want to go to “System” and make sure that the following are unchecked on the Motherboard tab:

  • Floppy
  • Network

Click on the Processor tab and make sure that you have 2 or more CPUs set for your virtual machine.

The next few settings are rather simple:

  • Display: Video Memory with a minimum of 128MB
  • Storage: Click “Empty” and then click on the CD at the top right. Choose your High Sierra ISO file

Now you’ll need to click “Ok,” and save all of the changes you’ve made. Close out your VirtualBox now.

Apple is very strict on the system that their operating system runs on, so it’s very important that you do your best to configure your virtual machine in such a way that it tricks the installer to thinking you’re on a retail machine.

We’ll now be going into the Windowscommand prompt.

You’ll do this by:

  • Clicking the Start Menu
  • Typing “Command Prompt”
  • Right-clicking on the Command Prompt desktop app
  • Choosing Run as administrator

It’s very important to follow all of the following command prompts exactly. Your goal is to run each command, one by one, hitting the Enter button and waiting for the command to complete successfully.

Remember that VirtualBox needs to be closed before running these commands, or it won’t work properly.

You have to make sure that the virtual machine is properly named “High Sierra” for this method to work. If not, you’ll be able to go back and make changes to the name to get everything to work properly.

Once all of the commands are completed, and there are no errors, you’ll then be able to open up your VirtualBox and get macOS High Sierra installed properly on VirtualBox.

It’s a long process, but we’re almost done with your installation.

Running VirtualBox and the macOS Installer

You’ve almost learned how to install macOS on VirtualBox entirely, and we’re on the home stretch. You’ll want to open up your VirtualBox and then click on your virtual machine that you set up earlier.

Now, click “Start.”

There will be a lot of information displayed on the screen as everything starts running. I recommend stepping away from the machine and letting it run for a few minutes before coming back. Some errors can hang for 5 minutes or longer.

If you’ve done everything properly, you can be confident that the installer will boot properly.

You’ll eventually be presented with the option to pick a Language. If you’ve reached this point, you’re doing very well and are almost ready to run your macOS.

The next steps can be followed:

  • Choose your desired language, and click
  • Click “Disk Utility” and then
  • Click “View” and then “Show All Devices.”
  • Click on your empty virtual drive that has been setup and click “Erase.”
  • Choose the following settings:
    • Name: Macintosh HD
    • Format: Mac OS Extended (Journaled)
    • Scheme: GUID Partition Map
  • Click “Erase” and close Disk Utility when the process is complete.
  • Click “Reinstall macOS.”
  • Click “Continue.”

You’ll come up to one point where you’ll be asked to choose a hard drive, and you’ll want to select the Macintosh HD partition that you just created with the Disk Utility.

We’ve successfully copied all of the files on the virtual machine, but we’re not done just yet.

Exit your virtual machine and then go back to your virtual machine’s settings. You’ll need to change up your Storage settings. Click on your ISO for High Sierra in the “Storage Tree.” You’ll click that CD icon just like we did earlier and then choose “Remove Disk from Virtual Disk.”

You need to do this to unlink the ISO from your virtual machine.

Start up your virtual machine and you should come across a black screen with the EFI Internal Shell. You’ll want to look for FS1. If this is listed in yellow, click on the virtual machine and then type fs1: and hit the Enter button.

You should be in the fs1 directory.

Type in the following commands:

  1. cd “macOS Install Data”
  2. cd “Locked Files”
  3. cd “Boot Files”

Now we’ll run the installer by running: boot.efi and hitting enter.

If everything goes well, you’ll come across a graphical installer and will just have to work through the prompts. The virtual machine will reboot eventually and then you’ll need to go through the settings and the rest of the setup process.

Soon enough, you’ll be right inside of macOS, where you’ll be able to start using your mac virtual machine on Windows.

Oracle Virtualbox On Mac Os

Having a virtualbox mac OS is the easiest method of using mac as and when you need it. In addition, using virtualbox is far less complicated than the dual boot hackintosh method we have looked at previously.
