Hi Claudio,
As I said - our specialists are working hard to resolve the issue. Unfortunately, addressing the problem might take a while. Thus, I do not have any further information at the moment.
Are you currently running macOS Catalina? If yes and Z-SUITE runs fine - please, pass me your Mac specification (you can send it to me via PM). We would like to gather more information which may help us to find a solution.
Best regards,
Karolina
