All you need: hdiutil create 1016.dmg -size 16g -layout SPUD -fs HFS+J hdiutil attach 1016.dmg -noverify -nobrowse -mountpoint /Volumes/InstallBigSur sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/InstallBigSur hdiutil detach /Volumes/Install\ macOS\ Big\ Sur hdiutil resize -sectors min 1016.dmg

@gatetester If you created the virtual machine as Windows 10 x64, probably VMware didn't format the disk. Either create a new machine as MacOS 10.14, start it once and then switch to Windows 10; or use Disk Utility in the existing virtual machine to format the disk for MacOS.

Based on that, here is my solution: 1. Install Catalina the usual way 2. When it fails to boot, use a Mojave dmg to boot into recovery 3. From Terminal rm -r /Volumes/Macintosh\ HD/System/Library/PrelinkedKernels mkdir /Volumes/Macintosh\ HD/System/Library/PrelinkedKernels kextcache -c /Volumes/Macintosh\ HD/System/Library/PrelinkedKernels/prelinkedkernel -K /Volumes/Macintosh\ HD/System/Library/Kernels/kernel -l -- /Volumes/Macintosh\ HD/System/Library/Extensions /Volumes/Macintosh\ HD/System/Library/Extensions/IOACPIFamily.kext 4. Shut down and set the hard disk as startup disk. For convenience, the commands can be saved into a txt file on an USB drive and accessed in Recovery from Terminal with cat filename.txt

You can try to create an install dmg from the app and use it as an install disk in VMware. In Terminal hdiutil create -o ~/Desktop/MojaveInstall.cdr -size 7g -layout SPUD -fs HFS+J hdiutil attach ~/Desktop/MojaveInstall.cdr.dmg -noverify -mountpoint /Volumes/install_build sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build hdiutil detach /Volumes/Install\ macOS\ Mojave For details see https://gist.github.com/jamieparfet/0479c938495f88d1b75b30aff318f735​ and How to create a bootable installer for macOS - Apple Support

Instead of using the Install macOS 10.15 Beta.app, it is better to create a dmg. Here are the steps adapted from Create an ISO from the mojave installer app · GitHub hdiutil create -o /tmp/1015.cdr -size 7g -layout SPUD -fs HFS+J hdiutil attach /tmp/1015.cdr.dmg -noverify -mountpoint /Volumes/install_build sudo ~/Downloads/Install\ macOS\ 10.15\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/install_build mv /tmp/1015.cdr.dmg ~/Desktop/Catalina.dmg hdiutil detach /Volumes/Install\ macOS\ 10.15\ Beta When using Install macOS 10.15 Beta.app, VMware creates a temporary dmg inside the virtual machine, then deletes it. By using the Catalina.dmg, the installation time is shorter, you can use the dmg to boot into recovery (OS set to Windows), and you can easily reinstall Catalina.
