Has been asked in the past many times with no response from Graphisoft. It's really annoying for me, too, and ArchiCAD is the only application on my Mac with this issue so it isn't an OS X issue, but a Graphisoft programming issue.

I'm the one that complained about this awhile back and your post just made me realize that I am not seeing the popup. Both in 18 or 19. The only thing that has changed is that I am running off of a Temporary License because the new Archicad Software Key and my computer are not playing nice and this was Tech Support's solution while they dig into it.
Maybe the WIBU key stuff is the culprit and not Archicad?

We know about this problem, but unfortunately there is a limitation with the digital signature of ARCHICAD and the Mac Firewall at the moment. As soon as it is possible, we will fix the issue!!
