Hello, I have updated the Mac 64-bit BETA. This version should install and work on 10.15 Catalina. This is expected to be the final Beta release prior to a final 64-bit release soon.

Known issues: In current beta versions of 10.15 Catalina, some extra black lines show in the display. We are working to address this issue.
