Hi! I've got a Macbook with with Leopard v10.5-something installed. When I installed the latest update and was at about 25% done with the "writing"-part it suddenly failed. I got a message prompting to restart (I think it said that it was something wrong with the source from which it was writing), when I restart the computer I get another message promting me to restart. My backup is a few months old, so I wonder if there is some way around my problem?
