After trying for an hour and failing to get Transporter from Windows talking to Transporter/Importer on Mac, I gave up and transferred as a file, using Windows Transporter to write a .pvm, ~117GB and copied that file to my Mac desktop. However, trying to import this PVM into a new VM on Mac, the Installation Assistant is completely hung, at "Transferring your PC", "Preparing to transfer...". The progress bar has not even started. It has, however created a the 74GB PVM in my ~/Parallels folder, which is the size that it said it would be at the start. Now what? This is a pretty important feature to me, as the org I'm working for is all Windows based, so slurping up their IT-approved Windows image is critical to using enterprise apps etc.
