In the Users & Groups preference pane, there's a checkbox marked Allow user to administer this computer. Is it checked? If not, do you have any other user accounts?

it's not checked, but in order to check it i have to unlock the changes by inserting the username and password and guess what? the one i used to log in and out doesn't work
here's the whole story: 3 years ago i bought this 24" imac from another person, who bought it refurbished and kept it for a very short time; i changed the name of the user by a complex procedure i can't recall anymore, in order to have my name on the disk and so on. i remember i entered into some sort of "root" mode, and from then on, despite the name and password i had set while installing the OSX, i had "System Administrator" as username and a different password i had to set up. since then that worked fine, until yesterday, when i installed the new OSX. i had my original account, this new System Administrator account and a guest account. now the SA account is gone, i am using the old account (but nothing's changed, and i've been able to log in and out fine), but this user name and password doesn't allow me to install any new software or system update, nor the old SA account and password.
i'm afraid it's a bit of a mess, but there must be some way to overcome it, right?
thanx for your support!

You went wrong at the very beginning by not erasing the hard drive of a used computer before starting to use it yourself. I suggest you do that now.

wow, that sounds scary. luckily i just bought a new hard disk so i can have 2 total backups. i'll finish sorting out a few things and the i'll try this way, i'll let you know how it goes.
thank you a lot!

hello, i still didn't try erase the startup volume because, for some reasons that i can't solve now, i'm not able use the assisted backup function of my hard disks. i managed to manually copy the folders with my files and archive on one of the hard disks, not the system files and applications, but those i can get back most of them.
my question is: can i try to erase the startup disk, re install osx, and then place back my files without problems?

I have no way of knowing that. You obviously have a damaged system and I don't know why you're unable to back up in the usual way. If you didn't back up when your system was working normally, there may be no easy way out now.
