Productivity? I really don't see the benefit of Catalina over High Sierra.
Once I get home from work, opening up Catalina is fine, it's full of things to stop me working, Arcade, App Store, AppleTV, Apple Books, Audiobooks, Podcasts, Apple Music.
But why the hell would anyone deploy this distraction into a working office environment? I just can't see any benefit over El Capitan/High Sierra. I really don't need a desktop wallpaper that changes with the time of day and I can live without dark mode/auto mode.
