I reinstalled 10.4. On restarting the computer (a G5) it asked for my name & password. It has never done that before. But it WILL NOT accept my name & password. BUT I am certain what the name & password are as I use the same ones on ALL my computers. Plus I have a backup HD and it has the same name & password. So I restarted from the 10.4 install DVD and went to where one can change the password. Obviously I put in the same password that I have always used. I restarted. But the problem remains. Anyone have any ideas?
