-The script assigns the minimum required storage size for the installation. After the installation is complete, the storage size may be increased. First increase the virtual disk image size through VirtualBox Manager or `VBoxManage`, then in Terminal in the virtual machine run `sudo diskutil repairDisk disk0`, and then from Disk Utility delete the "Free space" partition, allowing the system APFS container to take up the available space.
