Software update works. Only made one little change, though, that I noticed, though no record of it in console. Can anyone else find out where the changes are logged? It said none of my software needed updating, but it did make that little change.
Weird. OK, the change was it changed my software update icon in my dock to a little OS X cd with an orange arrow, in place of the gray icon it has now. But when I logged out, and logged back in, it was gone. Must have been a test.
