Prior Mac OS versions will find Security Update 2017-001 Sierra or Security Update 2017-004 El Capitan available in the Updates section of the Mac App Store as well. Answer: A: 10.10 is no longer available for download. I finally had to restart the computer and download 10.12.2 separately (it no longer showed as an available update). I changed my mind about iTunes and clicked to stop the download.
I clicked to upgrade the system to 10.12.2 and at the same time a new version of iTunes. When I try the update to Yosemite, though, I get the spinning cursor and it stays that way. I first did the 'Software Updates' which was ready in a few minutes. The 'more info' gives me (among others): Model name: iMac Model identifier iMac 11,3.
