And yet it happens to me 2 of 2 times
I’m aware my configuration isn’t officially supported (Mojave running on a 2008 Mac Pro), but I fail to understand how this could be related. That’s the only thing I expect to be rare enough on my setup resulting in no one experiencing the same issue. I don’t have a supported Mac at hand anyway.
I’ll try again, re-downloading the installer, perhaps
Thank you, Douglas, for all your suggestions and help.
