Reset manual settings (?? all I know is the Apple guy told me to restart the computer holding Command, Option, P and R I think)
Repaired permissions
Repaired disk (worked somewhat because it showed me the available updates but when I went to download them they said the server was unreachable and when I re-opened Software Update the updates were no longer visible)
Does anyone have any other brilliant ideas???
THANKS!
PS: The last successful update was on March 20 2010 with Safari 4.0.5 and a Digital Camera update.
