Everything seems to be is working fine. Is it a good idea to move on to a newer operating system, or leave good enough alone.
I see on Wikipedia there are newer systems: Sierra, High Sierra, Mojave, Catalina. Is it just a matter of going to the app store and hitting a download button? My wife used to take care of this, but she died. Thanks in advance. Andy
