Thanks! Worked for Mojave. Here's the modified steps for nubies like me... Create a sparse disk image: sudo hdiutil create -o Mojave -size 8G -layout SPUD -fs HFS+J -type SPARSE Then mount it: sudo hdiutil attach Mojave.sparseimage -noverify -mountpoint /Volumes/install_build Run the create install media program: sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build Detach Apple's high Sierra volume: sudo hdiutil detach /Volumes/Install\ macOS\ Mojave/ sudo hdiutil convert Mojave.sparseimage -format UDZO -o Mojave.dmg Then use VMWare Fusion to create a new disk image using Mojave.dmg you just created.
