When I ran software update it listed the 10.6.8 combined update, I'm assuming that's what is meant by "combo". The install disc I have is the original 10.6 disc so I'm also assuming that the combined update saves from having to update for each update between 10.6 and 10.6.8
I actually have solved my own problem, I didn't repair the permissions, I simply manually downloaded the installer from Apple. It would appear that there is some difficulty downloading the OS update if airport is out of date, which (by default) it is when you load 10.6.
I would recommend that other users download and install one item at a time when updating from 10.6 and install the airport update first. That resolved my issue.
Thank you for providing your solution.
Combined & combo updates are 2 different kinds of updates. The combined from Software Update only installes the items your model Mac needs. The combo update installs the whole shabang wheither your model computer needs it or not. It sometimes clear up issues that the combined install misses.
I did a clean install on a computer the other day. When I ran Software Update I got an error message about the Mac OS X Update Combined 10.6.8v1.1. This computer is networked via a ethernet cable. I noticed that only 10% of the Combined Update was downloaded.
I quit Software Update then ran it again. It finished the download at which point I installed all the updates.
It's interesting that you were connected via ethernet yet still had a similar issue. I wonder if perhaps our hardware issues that prompted the clean install may have been similar?
When I attempted to run software update again, it seemed to think that it had completed the download for the 10.6.8.v1.1 update, even though it listed it at over 1Gig, and had "completed" after mere seconds. I know my wifi setup isn't THAT good, and even if it were, I've never seen a wireless connection allow for download speeds of that magnitude.
I wonder if there is something missing from the original install discs that causes trouble with network connectivity? This is conjecture, I really don't have a solid working knowledge of the Mac OS X network tools. When i downloaded the intaller package from the website it seemed to resolve all my issues.
My clean install was done on a brand new HDD with a new partition, my unit seems to be functioning normally (for) now. Fingers crossed...I'm a teacher and my system crashed the day before labour day, taking with it a LOT of things I had prepared, and not backed up due to my foolish weekly backup schedule on Time Machine.
Thanks all for the suggestions and the help, interesting things to discuss!
