I was able to get Catalina working in a VM but I am having a few issues: 1. Network connection has to be enabled each time to access the internet 2. Cannot move anything around on the desktop, windows won't budge, icons won't move. 3. Can run some programs but the one I wanted to test, ArtStudio Pro, always crashes, have tried several different configuration settings to memory and graphics. Note that ArtStudio Pro did not work when I had 10.14 as the VM before I updated to the beta. 4. Memory allocation for Graphics is stuck at 256mb in the Mac VM even though I have set it higher in the configuration. 5. iMovie is not in the App Store (yet) so I was able to copy it over from my Mac but won't run as the graphic settings are not sufficient. I would be interested in other people's experiences with Catalina and any solutions. Public Beta 3 will be released tomorrow so will see if it makes any difference.
