First, we must create a temporary disk image:.

Next launch the Terminal application by hitting Command+Spacebar and typing “Terminal” and hitting the return key, or by launching it directly from the Utilities folder.

The MacOS installer app should be in the /Applications folder and be labeled as “Install macOS Big Sur.app” or similar, keep it there and make note of the file name.

For MacOS Big Sur, macOS Catalina and MacOS Mojave, go to the Mac App Store (or use this method to download full macOS installers) and download the installer applications for the macOS version you wish to make an ISO file of.

Get the MacOS Installer application that you wish to use:.

We will be focusing on making an ISO file for macOS Big Sur, but you can use this same approach for making an ISO file of MacOS Catalina and macOS Mojave too. For the purposes here, we’ll walk through how you can make a MacOS Big Sur ISO file by using the terminal. app file and do not arrive as a disk image, to create a MacOS ISO file requires a sequence of steps through the command line, or the use of a third party application. The canonical discussion thread on the VirtualBox forums that covers this in more detail is here.Because the macOS installer application is an.

There will never be any way to run a VirtualBox image that ran on an Intel Mac on an Apple Silicon Mac. So, not only will VirtualBox not work on Apple Silicon, it will never work on Apple Silicon. they don't use any of the standards built up in the PC ecosystem over the last 40 years. None of these take the same form on the Apple Silicon platform - i.e. These include system memory, various bus controllers (PCI, USB), hard disk controllers, sound cards, graphics, BIOS/UEFI, etc. So, it means not only that VirtualBox only runs on x86 CPUs, but also that it requires all the other elements of the x86 platform. However, it appears from various discussions I've seen on this topic that many users don't really understand what this really means.

As per David Leitko's answer, VirtualBox is an x86 (more specifically, AMD64/x86_64) virtualization hypervisor.
