I think it's safe to say the house iMac is officially retired, and has been replaced with a huge old Toshiba laptop, running an #ubuntu 16.04 variant called Accessible Coconut. The Main Squeeze likes the web browsing speed improvement of the new GNU Linuxified notbook over that of tghe even older iMac running that Safari thing. I gave him a login, and everything; isn't that cool! LOL. It took a long time to get him this far. True, my Thinkpad and the other Toshiba run better, for my purposes, He wants big screen and keyboard, and this machine was a long-ago gift from his mother, so, here we are.
