My old imac with Snow Leopard 10.6.8 was super slow.
I decided to do a clean install after backing up on Time Machine. When I reinstalled Snow Leopard, it asked for an account name so I just put in a logical one. I then went to TM and found that none of the files I wanted were there. Reading info about this, it seems I made a new account and that if I can rename the account to the original name, I may be able to get to those files.
Unfortunately, I cant recall my old account name.
