I have it installed and have used it before with no issues and VBox itself tells me that Hardware Acceleration is available so why is Rosetta telling me its not!?

Hi, you can try the software in step 4 here as a starting point:

But it seems some machines will not run VirtualBox tasks successfully at the moment - they get an MKL fatal error in Virtualbox in the first 20 seconds or so of processing. Hopefully it is something they can fix.
