MDS Fails- Error: system reboot failed


I have been testing out MDS for possible use in our environment for the small number of Macs we have. I have created a Workflow that includes Mojave with about 8 applications. When trying to apply to either of my test systems It gets to 100% Preparing and then hangs showing the error that the system reboot failed. A manual reboot does not get the process to pick back up. Any help would be appreciated.
MDS v 1.6


Are you installing macOS? It is macOS installer that does the reboot, so something in the hardware is stopping it. Try resetting the SMC and resetting the PRAM.
