Describes a scriptfor building and destroying a macOS Big Sur virtual machine built using a script.

The script you are using is published as vm-configure on github, so please download it from github or download it from here.

See the link below for the vm-configure folder configuration.

/host-osx/macOS-BigSur/vm-create.command

This is a script for building macOS Big Sur virtual machines.

The location of the script file is in the current directory.

SCRIPT_DIR - (dirname "0")
cd "$SCRIPT_DIR"

We determine if there is an iso file that is the installation media for macOS Big Sur in the script execution directory, and if it does not exist, we are creating an iso file.

if ;[ ! -e "${SCRIPT_DIR}/BigSur.iso" ] then (album)
  ...
Fi

If there is no macOS Big Sur installer from which to create an iso file that will be the installer for macOS Big Sur, download it from Apple with the softwareupdate command.

    if [ ! -e "/Applications/Install macOS Big Sur.app" ]; then (album)
        softwareupdate --fetch-full-installer --full-installer-version 11.0.1
    Fi

Creating a 16G disk image to write the installer.

    hdiutil create -o "/SCRIPT_DIR BigSur" -size 16G -layout SPUD -fs HFS+J -type SPARSE -volname BigSur

Mounting the disk image you created.

    hdiutil attach "/SCRIPT_DIR BigSur.sparseimage" -coverify -mountpoint "/Volumes/BigSur"

Writing the installer to a disk image mounted using the createinstallmedia command included with the macOS Big Sur installer.

    sudo "/Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia" --volume "/Volumes/BigSur" --nointeraction

Detaching disk image.

    hdiutil detach "/volumes/Shared Support"
    hdiutil detach "/volumes/Shared Support 1"
    hdiutil detach "/volumes/Install macOS Big Sur"

Converting the disk image to an iso file that can be used by the virtual machine.

    hdiutil convert"/SCRIPT_DIR Catalina.sparseimage" -format SCRIPT_DIR UDTO -o

I’m changing the file extension and cdr to iso.

    mv "SCRIPT_DIR/BigSur.cd.iso SCRIPT_DIR r"

Deleting disk images that are no longer needed.

    rm "SCRIPT_DIR/BigSur.sparseimage"

Defines the name of the macOS Big Sur virtual machine on VirtualBox.

VM_NAME: "macOS-BigSur"

The virtual VM_NAME virtual machine is defined on VirtualBox to determine if it does not exist, and if it does not exist, it is in the process of building the virtual machine.

if ;[ ! "`vboxmanage list vms | grep '"'"${VM_NAME}"'"'`" ] then (album)
  ...
Fi

The virtual machine to be created in VirtualBox is set with the vboxmanage command.

See here for the parameters that can be set.
