If you intend to install software in your SheepShaver VM, then you will need to expand that blank 30GB file and move your Mac OS 9.0.4 installation to it. Please note that the 250MB base image is not intended for users to install more software. It already contains a compatible ROM file (Mac_OS_ROM.rom), a ready 250MB disk image on which Mac OS 9.0.4 is already fully installed (as well as an optional empty 30GB, yes 30 gigabytes, disk image to accomodate heavy disk space use). This bundle was put together by 'that-ben' and is intended to be the easiest possible for starters.
