TMG 9 with Windows 10 and Parallels 11 in The Master Genealogist v9 Posted September 23, 2015 · Report reply Thanks Glenn. Just to make sure I understand.... upgrading to Parallels 11 has worked fine for you with Win 8.1. However there is a disclaimer that the Virtual Machine's graphics device is not compatible with Win 10? Can you tell me how that might effect things? If I'm going to get Win 10, I want to get it while it's still a free upgrade. I also use only the same Windows programs as you (except for the .csv converter) plus a couple of small utilities similar to your converter. Have you heard of anyone else's experience who has tried to use W10, P11 and TMG?
