On older computers, a fixed size virtual disk will provide an extra performance boost. If you are using one of the VirtualBox 6.x versions, select VDI (VirtualBox Disk Image) as the virtual hard disk type you will create on the virtual disk configuration screen and click Next.Īlso, if you configure the virtual hard disk as Fixed Size while creating a virtual machine with VirtualBox, a space equal to the size of the virtual disk will be allocated on your host disk.

But if you are doing a clean installation, choose the Create a virtual hard disk now option and click the Create button to continue. If you have the virtual machine disk ready in the Virtual Hard Disk window, you can add it and run your macOS system directly. If your host computer is getting errors and stuck on the logo during installation, we recommend that you configure the virtual processor core count to an appropriate 1 and test it. Under normal conditions, a macOS virtual computer runs smoothly with a memory size of 4096 (4 GB).Īlso, set the number of 2 or 4 vCPUs for the macOS system to work more efficiently on the virtual computer. If your host RAM has a capacity of 16 GB, assign a RAM size of 4 GB or 8 GB in the Memory Size window. You should allocate RAM size and virtual processor to the virtual machine according to the hardware performance of your host computer.

In the window that opens, go to the location where you downloaded the ISO file, select the relevant file and open it.Īfter following the basic steps, click Next to proceed to the next step.

To add the Ventura image file to the virtual machine, select Other from the ISO Image drop-down menu. In the Version section, select which version of macOS you will install, and then click the Next button. In the Create Virtual Machine window, type the version of the macOS system in the Name field and select Mac OS X from the Type field.
