reinstalled Snow leopard and can not open, dosn't accept my usuale password, how do I get pass this to open my computer?
Reboot into your Leopard bootable backup/clone or restore your Time Machine backup and try again.
Try booting from the instal disc, you can change the password form one of the menus I think it might be under utilities.
Did you ever resolve your issue, and if so, how?
Rather than reopening a nine-month old thread, it's better for you is to start your own discussion, providing the salient details of your issue.
