  1. Install Virtualbox On Macos Monterey
  2. Virtualbox Mac Os X Sierra

VirtualBox 6.1 did not install on macOS 10.15.0. Neither VirtualBox 6.0.14 or 6.1 would install on macOS 10.15.1 or 10.15.2. Since the rest of the team has (unfortunately) already updated the OS to newer than 10.15.0, it looks like we're dead in the water and will continue using our 5 year old MBP's for the time being. The default resolution of macOS or any guest OS that you install on VirtualBox is 1024×768, which is probably not what you want. However, this can be changed using the macOS screen resolution code. Close VirtualBox, run Command Prompt as an administrator, and copy/paste the first line from the screen resolution code file.

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.

Install virtualbox on macos catalina
  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.

Why?

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.

Macos

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.

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.

There are three major steps to install OS X High Sierra in VirtualBox in a Windows 10 host:

Install Oracle VM VirtualBox on Windows. First and foremost, pull up the VirtualBox. Download MacOS Mojave ISO. You have to get macOS Mojave ISO in the link. Install macOS Catalina 10.15 on VirtualBox on Windows PC. Now you are done completely with the steps of macOS 10.15 on VirtualBox. Therefore, open VirtualBox and start the installation of macOS Catalina 10.15 on VirtualBox. After that, you run the installation just follow the steps to install properly macOS Catalina 10.15 on VirtualBox. Download macOS Catalina ISO. You’ve to download macOS Catalina ISO from the.

I used a Mac in the first two steps and completed the last two steps on the target Windows machine.

Downloading High Sierra

At the time of this writing, High Sierra was the most recent version of Mac OS X that could be installed in a VirtualBox virtual machine. However, High Sierra is no longer available for download from the Apple App Store.

High Sierra can still be downloaded from third-party websites. I downloaded a copy through this macOS High Sierra Patcher Tool for Unsupported Macs. Once the tool is downloaded, open it and use its built-in downloading feature. In the menu bar, select Tools > Download macOS High Sierra…

Install Macos Catalina Virtualbox Windows 10

After a few minutes, you should have a copy of the High Sierra installer.

Preparing an ISO

Once you have a copy of the High Sierra installer, an iso file must be prepared to install it in the virtual machine. The only way I could get an iso that worked on VirtualBox was by using the script suggested in this superuser.com answer:

Note that this is the original script, and it was written assuming that the High Sierra installer was downloaded from the App Store into the Applications directory. Before running the script, make sure the installer variable points to the right location of your High Sierra installer.

Setting up the Virtual Machine

Switch to the Windows 10 machine in which you want to set up the virtual machine. Copy over the iso created in the previous step and make sure both VirtualBox and its extension pack are installed. If not, both can be downloaded from this page. With both pieces of software installed, create the virtual machine the following steps:

  1. Open VirtualBox
  2. Click New to create a new virtual machine.
  3. Enter the name for the new virtual machine; e.g., High Sierra, and click Next.
  4. Select the amount of RAM for your virtual machine, making sure you leave enough for Windows, and click Next.
  5. Choose Create a virtual hard disk now and click Create.
  6. Leave the default setting VDI (Virtual Disk Image) and click Next.
  7. Leave the default setting Dynamically allocated and click Next.
  8. Choose the size of the virtual hard disk and click Create.
Macos

At this point, the virtual machine has been created, but it requires extra configuration to install High Sierra from the iso file you created earlier.

  1. Select the High Sierra virtual machine you just created and click Settings (the button with the cog icon).
  2. On the side menu, click System.
  3. On the Motherboard tab of the right panel, uncheck the Floppy option from the Boot Order list.
  4. Switch to the Processor tab, set the number of Processor(s) to 2 or more and check the Enable PAE/NX option.
  5. On the side menu, click Storage.
  6. Under storage devices, click Empty.
  7. Under Attributes, click the optical disk icon.
  8. Select the High Sierra iso, and check the Use host I/O cache option.
  9. On the side menu, click Display.
  10. Set Video Memory to 128 MB.
  11. Click OK to save.

Virtualbox Mac Os X Sierra

For the last configuration steps, close VirtualBox, open the Windows command line prompt, and run the following commands:

Install Snow Leopard Virtualbox Windows 10

Finally, open VirtualBox again, select your High Sierra virtual machine, and click Start. This will boot your virtual machine with the High Sierra iso set up earlier. Simply follow the steps to install the operating system.
