software update does not work after re-install of 10.6.8
I re-installed my system software, upgraded to 10.6.8, restored from time machine and now when I use my software update it says "failed cannot connect to the internet." I checked and I am connected. I did download and install a "combo update" that I found through the apple communities. My itunes also needs to be updated and my internet is very slow. I use an airport and it is only this mac that is slow the rest of the devises in the house are fine. Please help!
Mac Pro 2 x 3 Ghz Duel Core Intel, Mac OS X (10.4.11), 6 GB RAM
