Hi. Thanks for you suggestion. I tried "version --dup" in terminal and while it appears to clear up cache it did not appear to work properly or was failing to resolve some issue. Showed an error about not finding a web site location. Also it did show an update was available. There was also a message that some optimizations were needed before the update could proceed. Needed about 1.5GB memory which was available. It appears to me that when trying to update that the download is not completed. Once download was completed it asked to update and it failed.I then get the message to try again later as if there might have been a bad internet connection such that the download was corrupted. Sorry if this is a little vague as I don't have phone with me so I'm simply recalling what happened. Should I have run "version --dup" as superuser? Any other insights?
