In my own experience. Best fix is to delete it and don't use it. A mac will run windows and linux fine if used in an external USB, or bootcamp will assist with a permanent install of windows. Not sure the scope of use with VM needs but I hope this helps. I have been trying (and failing) to set up any kind of internet connection for my Windows XP virtual machine and would appreciate some assistance. Details are as follows: Virtualbox 4.3.0. Mac OS 10.6.8 host. Windows XP SP 2 guest.

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.

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.

Virtualbox vm quit unexpectedly mac os

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. Slack earnings report date.

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.

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.

Recently when working with a client we encountered a situation where it would be beneficial run a Mac VM on our Mac laptops, so I decided to investigate. I was in luck! It turns out this is actually really easy to do.

To get started, download Yosemite from the App Store.

Virtualbox Vm Quit Unexpectedly Mac Os

Fair warning: the download is ~5.5GB. It took me about half an hour to download, but depending on your connection speed your mileage may vary.

My Setup

  • 2015 Macbook Pro
  • 16 GB RAM
  • 2.5 GHz i7
  • 512 GB SSD
  • VirtualBox v4.3.x

The following instructions are heavily borrowed from frdmn's notes blog with additional notes added as needed.

Creating the Mac OS X Disk Image

  1. Install iesd, to customize OS X InstallESD:
    gem install iesd
  2. Turn install image into base system:
    iesd -i '/Applications/Install OS X' -o yosemite.dmg -t BaseSystem
  3. Convert into UDSP (sparse image) format:
    hdiutil convert yosemite.dmg -format UDSP -o yosemite.sparseimage
  4. Mount the InstallESD:
    hdiutil mount '/Applications/Install OS X'
  5. Mount the sparse image:
    hdiutil mount yosemite.sparseimage
  6. Copy the base system into the sparse image:
    cp '/Volumes/OS X Install ESD/BaseSystem.'* '/Volumes/OS X Base System/'
  7. Unmount InstallESD:
    hdiutil unmount '/Volumes/OS X Install ESD/'
  8. Unmount the sparse image:
    hdiutil unmount '/Volumes/OS X Base System/'
  9. Unmount both mounted disks:
    diskutil unmountDisk $(diskutil list grep 'OS X Base System' -B 4 head -1)
    diskutil unmountDisk $(diskutil list grep 'OS X Install ESD' -B 4 head -1)
  • If you have difficulty/receive an error, you can also do this in Disk Utility. 'Right' click on the disk image (either InstallESD.dmg or yosemite.sparseimage) and then select Eject Disk Image. Repeat for the other disk as needed.
  1. Convert back to the UDZO compressed image format:
    hdiutil convert yosemite.sparseimage -format UDZO -o yosemitevagrantbox.dmg

Common Error

What to do if you encounter the this error on the last step:
hdiutil: detach failed - No such file or directory

  1. Remount the sparse image file. One way do to this is to open Finder and double click on the sparse image file.
  2. Use hdiutil detach instead of hdiutil unmount:
    hdiutil detach /Volumes/OS X Base System/
  3. Re-run hdiutil convert command.

Creating the VM in VirtualBox

  1. Click 'New' or ctrl+N/cmd+N to create a new VM
  2. Give it a name, select Type: Mac OS X and Version: Mac OS X (64-bit) if these are not populated for you (they will be if you use 'Mac' in the name). Click continue.
  3. Default of 2 GB of RAM is adequate for a quick test, but if you plan on using the VM for more than 5 seconds I recommend 4 GB if you can spare it. Otherwise the lag is really frustrating. In any event, click Continue.
  • Note if you change the RAM to 4 GB you will need to change your chipset later.

Virtualbox Vm Quit Unexpectedly Mac

  1. If you do not already have a virtual hard drive leave the default selection and click 'create'.
  2. I used VDI, click Continue.
  3. I left the disk as dynamically allocated. Click Continue.
  4. I left the default 20 GB. Click Create.
  5. If you upped your RAM, 'right' click on the new VM and click 'Settings'. Then go to System -> Motherboard to change the chipset to PIIX3. Feel free remove 'Floppy' from the boot order while you're in there.
  6. 'Right' click on the new VM and click 'Start'.
  7. Select the disk image as an 'optical disk':
  • You do not need to create an ISO, although if you do it will still run normally. If you would like to create an ISO just run this command:
    hdiutil convert yosemitevagrantbox.dmg -format UDTO -o yosemitevagrantbox && mv yosemitevagrantbox.cdr yosemitevagrantbox.iso
  1. Wait a few minutes while the installer runs. Grab a coffee?
  2. Once the installer starts go ahead and select your language.
  3. Go into Disk Utility and create a formatted partition. Instructions for how to do this are in the 'Creating a formatted partition..' section below.
  4. When prompted, install on the partition you created in the previous step.
  5. Go through prompts as normal (iCloud, etc.). I personally didn't sign into iCloud/etc. for a test VM.

Creating a formatted partition with Disk Utility

How To Install Mac On Virtualbox
