Really no “advantage,” just a newer operating system with more bells and whistles, but also more security rules, AND a change in the programming that will stop older programs from running. Apple applications like Mail etc will have been upgraded with Catalina, and subsequently have upgraded/altered their data/settings if you opened them on Catalina, changes that the earlier versions of those applications, which will be reinstalled with High Sierra, cannot know about and therefore cannot parse.

I updated my MacBook Pro to Catalina, but now certain plugins in my music software do not work. I want to revert back to what I had before (I believe it’s high Sierra). So I tried to restore from a previous backup in time machine, but got the following:
“the system can’t be restored onto this disk because HFS systems can’t be restored to space sharing APFS volumes. ReInstall macOS on this disk and then use Migration Assistant to transfer data from your backup instead.”
does anyone know what this means, and how I could do get back to high Sierra?
Thanks
