My mother has a early 2009 24" iMac that was running Lion and the HD died last week. I ordered a new one and installed it. I used the Snow Leopard disk to format the drive and then ran a restore from the Time Capsule. Now, when it boots up, it makes it to the log-in screen, but none of the passwords work. The hints are all the same but no luck on the passwords. It appears the log-in screen is the Snow Leopard log-in screen. I'm not sure if that has anything to do with it. Any suggestions?
