What if I don't want to "upgrade" to a newer software.
I have MacOS High Sierra version 10.13.6. Early 2015. I am mostly satisfied with the way it works. I am afraid that if I upgrade to a newer version I will have lot of problems. Is it okay to stick with what I have? I am not a sophisticated user. Most of my computing is just word processing, email, spreadsheets (infrequent),- just typical stuff.
