Hello everyone, I just got Windows 7 64 bit on my Mac Pro 1,1. I used oscdimg to modify the ISO and activated it using my product key. I am downloading Windows 10 right now. I would like to get my Mac Pro 1,1 up to Windows 10. Once I do the upgrade, will I have the 64 bit version? And will it work with my Mac Pro? I appreciate any response I get!!
