Finally started the Mavericks Install that has been prompting me for months. Over 5Gb download. Started it and left to do stuff. Several hour later it appeared to have downloaded. Said "Downloaded" instead of "Install". Did prompt me to restart. But restart only took about 30 seconds, and afterward I was not upgraded to Mavericks 10.9.2. Still 10.8.5.  Software update no longer gives me the download option. Can't find anything that was downloaded to run. Any ideas what happened? Mac Mini 2.6 Ghz I7
