Lightroom Classic 9.2 is incredibly slow after updating Mac Pro to Catalina
I updated my 2013 Mac Pro to Catalina yesterday, and now Lightroom Classic, which was running perfectly fine on Mojave, is super slow. Adjusting sliders is painful..it takes a good two seconds for the slider to move, and simply switching between images in the library grid view takes a little over two seconds just to switch to the next image. That action was previously instantaneous. I am very disappointed and wish I could switch back to Mojave, but can't now. I know all about the performance suggestions (using GPU, etc), but nothing is helping.
