Is anyone else having trouble with software update. When I run it, it finds all the software needed to be updated. Then when I try to download it I get this message: The installation has encountered a problem. None of the checked updates were successfully installed. To try again, choose Download Checked Items from the Update menu and open the package from the Desktop. I clicked OK, and tried the suggested procedure, and got the same dialog. I also am unable to download Safari from apple's site. I thought just the developer seeds of Safari were pulled.
