Hi, guys. I wanted to update my OS to 10.5.6 with auto update. When I was downloading the update file, the internet disconnected for a while but it finished at last. Then the system failed to be updated with message" the file is damaged". I want to download again but the auto update always showed that the update file already downloaded and the system is updated with the damaged file. What should I do? how to deleted the downloaded message and let the system download again? where is the downloaded updated file? THanks of ur help ahead.
