VirtualBox and a VirtualBox Extension Pack?
VirtualBox is a virtualization program and essentially its purpose is to create virtual machines that can run on Linux, macOS or Windows operating systems on a desktop that is already under the control of another operating system. Using this software you can create a virtual machine, manage and access it with ultimate ease.
Also using VirtualBox, you can also integrate both your Windows 10 and macOS Catalina virtual machines allowing you to share files. There are also an abundance of many other interesting features included in VirtualBox and Mac OS can also affect the performance of your base Windows Operating system.
This new system USB wise will only support USB 3.0. If you install the VirtualBox Extension Pack this can help you in fixing the problem as it has the capability to connect to the VirtualBox which unlike the macOS system can cater for USB 3.0 devices also.
Download macOS 10.15 Catalina ISO Image
If you want to run macOS 10.15 using your VirtualBox virtual machine first and foremost you’re going to need a macOS Catalina image (ISO file). On here are the installation files that you need to install macOS versions 10.15. These images are available online however not all of them guaranteed to work with VirtualBox. In order to help you create a macOS ISO image below. This has been made from scratch, and will help you set up macOS Catalina 10.15 on your Virtual Machine in just a few minutes.
How to install macOS 10.15 Catalina on VirtualBox on Windows PC
Step 1: Download Catalina Final from the Mac App Store
The first step towards creating a macOS Catalina ISO file is to download macOS Catalina Final from the Mac App Store.
This is not possible if you can't access a Mac. If you do not have one, consider borrowing it from your friends or use a Virtual Machine. You will need it for about a 15 minutes. The consecutive steps can be completed on your Windows PC. The installer will launch once the process is complete. You only need the downloaded files. If you want to access the Installer File, you can find it in the Application folder.
Step 2: Create macOS Catalina ISO File
Find your macOS Catalina.App and move it to the Application folder. You must use the Terminal to convert the files to an ISO. You can find the Terminal in Applications > Utilities.
# Create a Catalina Virtual Disk Image
hdiutil create -o /tmp/Catalina -size 8500m -volname Catalina -layout SPUD -fs HFS+J
# Mount this Image to macOS
hdiutil attach /tmp/Catalina.dmg -noverify -mountpoint /Volumes/Catalina
# Use macOS Createinstallmedia Tool to create a Installer Image
# Unmount Volume Catalina
hdiutil detach /volumes/Install\ macOS\ Catalina
# Convert the Catalina.dmg to a Catalina.iso for Virtual Machine
hdiutil convert /tmp/Catalina.dmg -format UDTO -o ~/Desktop/Catalina.cdr
# Move and Rename Catalina Image to Desktop
mv ~/Desktop/Catalina.cdr ~/Desktop/Catalina.iso

Step 3: Install New VirtualBox 6.1.4 and then install the Extension Pack.
Now that we have unzipped the folder and we now have access to the image, we need to then install VirtualBox and also at the same time make sure that it is the latest version. You're going to want to go ahead and download, and install VirtualBox.
VirtualBox 6.1.4 (free): Download
If you remember we mentioned the VirtualBox Extension Pack, well you can download that here. Then open the application and click to install the extension pack on your VirtualBox.
Step 4: Create a New Virtual Machine
Now that you have successfully downloaded VirtualBox and we also have the ISO image ready, we are going to want to create what is called a new Virtual Machine. The first step of this is to go to the top of your VirtualBox window and click "New " button. What happens next is that a wizard will appear that will walk you through the steps of creating a Virtual Machine.
As the wizard guides you through the process of creating a virtual machine you are going to be asked various bits of information:
Name for Virtual Machine: macOS Catalina 10.15.
Type: Mac OS X.
RAM: We usually recommend this be around 50% of your physical RAM availability, so if your computer has 8GB RAM go ahead and select 4GB.
Once you have named your virtual machine and decided upon the RAM Usage it is next going to ask you what Hard Disk you want the Virtual Machine to use. You will see three options, do not add, create or use an existing one. Select "Create a Virtual Hard Disk" with 100GB and browse to where the "macOS 10.15 Catalina.vmdk" file was located and then finally click create!
Step 5: Edit the Virtual Machine
We have now finally created the Virtual Machine, however that isn't everything finished, we need to alter a few settings. And to do this, go into settings. From the list on the left select 'System'. There will be three tabs at the top, select 'Motherboard' and tick the box which says 'Enable EFI' and for Chipset from the drop down list select PIIX3.
Then in the Processor tab tick the box next to ‘Enable PAE/NX’ and increase the amount of core to 2 (presuming that is 50% of your CPU).
Next up in the settings select 'Display' from the list on the left. The first tab you should see should say 'Screen'. Here you can decide upon the Video Memory of your Virtual Machine, its ideal to set it at 128 MB and Graphics Controller is VMSVGA.
The final part of the settings process is to select USB from the lsit on the left and go ahead and tick the box that says USB 3.0 as if you remember it only supports USB 3.0 natively and not 2.0
Step 6: Add ISO Image
Open Storage tab, Click on CD/DVD icon and open your "Catalina.iso" image.
Step 7: Use Command Prompt to add the following code to VirtualBox
Close VirtualBox before follow this step, we are going to give you some code to add in to VirtualBox however you're going to need to do this through CMD or Command Prompt. Go to your start menu and type in CMD and you should see the below, if you do, go ahead and right click and click 'Run As Administrator'.
Code for VirtualBox (New): Download
Note: replace "Your VM Name" in this commands line with your Virtual Machine Name in step 3, then type in the following code:
- cd "C:\Program Files\Oracle\VirtualBox\"
- VBoxManage.exe modifyvm "Your VM Name" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff
- VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3"
- VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0"
- VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Iloveapple"
- VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"
- VBoxManage setextradata "Your VM Name" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1
Step 8: Install macOS Catalina in VirtualBox
Reopen your VirtualBox and click "Start" in the left-hand corner. This will turn on your Virtual Machine. Once you have seen the macOS Utilities, open "Disk Utility".
Select VBOX Virtual Disk and format it as "Mac OS Extended (HFS)"
Now, Install macOS Catalina on your VirtualBox Disk.
Once it has rebooted up. Turn off your Virtual Machine. Open VirtualBox, then remove "Catalina.iso" in Storage tab.
Once you have seen that the macOS Catalina installation has completed, turn off your VirtualBox.
Step 9: Run macOS Catalina VirtualBox
If you have followed all of these steps correctly which hopefully you have you can now open your Virtual Machine and start running Mac OS. As you would have to on a normal Mac you'll have to go through the initial set up and set yourself up an account however once this is done you can then use your Mac OS Virtual Machine to its full potential.
Now have you followed all of these steps you should now be able to start using macOS Catalina for whatever purposes you may need it for. Hopefully this guide has made the process of running macOS Catalina 10.15 on your VirtualBox easier than ever.
Now have you followed all of these steps you should now be able to start using macOS 10.15 for whatever purposes you may need it for. Hopefully this guide has made the process of running macOS Catalina on your VirtualBox easier than ever. This now means that you'll never need to settle for running a single OS again, you can run macOS alongside your Windows Operating system with ease.
