Hello, first of all, my appologies for deleting your previous post, we are fighting spammers on the daily basis, and I was carried away during clicking.
What you say is rather strange, but fortunatelly I encountered the same thing, but not in Espionage!
I downloaded the damn Adobe Flash updater, just as I did thousand times already, and when I doubleclicked on it it mounted as Google Updater??? and it was empty.
But when I check the mounted volumes in /Volumes folder the it is Adobe Flash updater, and there is a file inside, the updater app, but when I try to launch it, it says it does not exist.
So there is something fishy in High Sierra and Volumes, but I had no time to investigate it, because I encountered it during work, and today I’m away traveling.
I will come back on this, in the mean time if you find something on the google, please let me kniw,
Thanks
Zsolt
