Need to reset system password; don't have system Disk. 10.5.8
I'm trying to help a widowed friend setup a printer with her imac. Her late husband bought the computer used and she doesn't have the system disk and doesn't know the password setup by him. She also needs to take some system updates that also require that password.
How can I reset her password?
Please and thanks.
iMac, Mac OS X (10.5.8)
