I continue to install the latest macOS Catalina Betas. Today I installed Developer Beta 4 of 10.15.5. It seems to work just fine, very fast still. However, the Finder issues I have been experiencing have yet to be repaired. Perhaps they are only present because of something in my system, only time will tell. My main workflow Apps all seem to work well in this Beta update. This Beta has a Battery Health tracking feature for laptops which might be helpful. I am assuming the final of 10.15.5 will be released soon.
