To Reproduce
Steps to reproduce the behavior:

  1. Run make all
  2. Open runMacOSVirtualbox.log
  3. See error

Expected behavior
The ISO should be created.

Additional context

I have noticed this error before when I was trying to create the ISO myself. I think it has something to do with detach not working properly.

I have tried running the ejectAll function which succeeds but doesn't do the right thing. There is a process that is dissenting the unmount:

doing a sudo kill -9 with the PID of the process returned by hdiutil info then rerunning make all seemed to do the job.

Thanks for the feedback. Seems the script needs better / more checks.
