I am specifically interested in preview or thumbnail images not being displayed in the Browser, which is what is happening with my current setup--a MacPro (2013) running Mojave. The graphics card is an AMD D700. I am wondering if Catalina has an updated driver for that particular graphics card.
As an aside, I have been trying to create a boot backup drive but cannot get the Mac Startup Manager to recognize it. With a bootable backup, I could easily install and test Catalina with ON1. I have tried both Carbon Copy Cloner and Super Duper with the same negative results.
