macOS Catalina software update isn't showing as a software update for my Mac, why?
I have macOS High Sierra and macOS Catalina software update isn't showing as a software update for my Mac. I've checked pending downloads, checked my computer for software updates, but not sure what I can do get the new software. Any ideas on how to get the update when it's not showing in my App store?
