I downloaded and installed OS 10.15 Beta (Catalina) on an old computer. I have not tried to do thorough testing with Panorama X, but so far Panorama seems to work without a problem. One change in the System may affect some applications: most, if not all, of Apple apps have been moved to a new folder: /System/Applications/ instead of /Applications/. I had procedures that opened the Dictionary, and that had to be revised to use the new path.
As expected, Panorama 6 does not open under the new system.
