I've had four attempts and nothing works. I spoke to a very rude woman at Apple Customer Support to fix it. Her first and last suggestion was to reinstall the whole operating system. I said I was not confident that would work (seems from some of the posts here it's been true for others), and that I didn't have an infinite amount of data to waste on this. Very, VERY disappointed. This update would seem to make Windows 10 seem rather the gold class operating system.
