Just as an FYI . After I found the Virtual Box and VM download for updating Godox firmware on my MAC and downloaded it all (about 5 gb), when I tried to do anything wit all I got was the spinning beachball of death. Tried this several times and finally gave up. Going to just use my wife's older windows laptop and do it all there Plus, will wait for Godox / Adorama to release the Mac version that is supposedly being worked on. I would not think out to be too difficult to come up with that, myself.
Did you extract the .ova virtual machine file with
Unarchiver like the Microsoft page instructed before you loaded it? Or did you just try to unzip the .zip file by double-clicking and end up with another archive?
I'm on a 2012 MacbookPro with 8GB memory running on El Capitan. I didn't have any problems importing the .ova for the Edge on 64-bit Windows 10 VM and booting up into Windows 10 on VirtualBox.
