The reason I have not been posting recently has nothing to do with the holidays. My computer would not stop giving me prompts to install a software upgrade every day until I did it. When I finally clicked on the Install button, it was the last time I could do anything except turn it on and off. Somehow the upgrade installation got stuck at one point and could not finish, as if there was an impasse. Apple Care could not figure it out on the phone. Geel Squad at Best Buy could not fix it and shipped the computer to Apple, so now it is in California while I borrow Mom's laptop. One more reason to not like Apple because this never happened to me with any Windows computer.
