How to Create macOS Ventura VMDK for Virtual Machine

macOS Ventura was released in WWDC 2022. It was released with tons of new features and amazing changes. We are not going to deep dive into what new features or changes are added or what features were removed, as we are here to create a macOS Ventura VMDK file. For those who are interested in knowing more about the features and changes in macOS Ventura, they can use this link.

Before we start the process of creating a VMDK for macOS, you will need to understand that VMDK is a Virtual Machine Disk File or disk image file. It means that you are going to have an identical image of your macOS.

The VMDK file is used on different Virtual Machines. The file format can’t be used on Mac or Macbooks to perform a clean installation. It is only limited to virtual machines only.

I have already mentioned that you can’t use VMDK on Mac or MacBook, nor you are able to create one on Mac or MacBook directly. For creating a VMDK file, you will need to possess a macOS inside the virtual machine. For this, you will need to download VMware (install it on your system) and then you will install macOS Ventura on VMware.

You will need an ISO or DMG file of macOS Ventura before you start the installation of macOS Ventura on VMware. Here we have used VMware, but you can use any other software that you feel confident with. Virtualization software such as VirtualBox is a great alternative to VMware.
