could you please elaborate?
I use VMWare Fusion on my Mac and never had problems running a Teradata or Aster VM.
Should be similar with Parallels or Virtual Box, but you probably have to convert the VM images to work with those programs.
I tried to use Virtual Box and in past tried on Parallels (Running latest Mac OS).
Do you have details on how you set it up?
You could send it to my email that we had used in past.
