Problem with Leopard Software Update
Recently my Mac OS X Leopard Software Update stop working, when I try to do Software Update get ridiculous problem, and this is not good for my Leopard in the future. So I ask on some forum includes official forum from Apple.com
After look around for a while I got the solutions how to fix this problem. All need to do just go to your Terminal and deleted your cache corrupt. You can find you cache on ~/Library/Caches/com.apple.SoftwareUpdate/
Lets do it,Open your terminal then write this command
cd ~/Library/Caches/com.apple.SoftwareUpdate/
Then remove your old cache, with this command
rm *
And re-run your Software Update again
