This worked for me…

I have a unibody Macbook Pro 15” 2.53 GHz Intel Core 2 Duo.
I decided to update iTunes two weeks ago.
It was then, when I was prompted to input my admin password, that I realized that I had forgotten it. The hint didn’t even ring a bell!
I looked it up on the net and immediately found that the “easy” solution was to use the Mac OS X boot disk. Great! Problem solved!
I inserted the disk.
My laptop spit it right back out.
I reinserted.
Spit right back out.
I played that game for hours.
The next day I called Apple to find out my warranty had expired A DAY EARLIER!
So the disk drive is a separate issue…
But I did figure out a way to “back-door” into my Mac.
To “Hack-a-Mac” and reset the admin password.

This method is posted to assist those who are the OWNERS of Macs and NEED to gain access to their OWN machines.
If you are a waste-of-flesh thief…Kharma IS a *****…and she WILL catch up to you.
The following is what worked for ME on my machine.
I make no guarantees or promises that this will work for you.
All machines are as different as their individual users.

1) Reboot or restart your Macbook Pro
2) When you hear the boot-up “tone,” hold down “command “ and “s” keys simultaneously, until you see a black screen with text on it, when you see this, release the keys.
3) Wait for all of the codes to load.
4) Press the “return” key once to make sure you have a fresh root prompt.
5) Enter the following: /sbin/mount(space)-uw (space)/
**Do not type the (space)…this is where you will tap the spacebar…these spaces are important…but type everything else.
6) Press “return” It should say something like “removed orphaned unlinked files” or something
7) Now enter: rm(space)/var/db/.applesetupdone
8) Press “return”
9) Now enter: reboot
10) Press “return”
11) The machine will now reboot. It will ask you for language selection and go thru the intro video as it did when you first bought your machine.
12) It will ask if you want to transfer data…I did. I didn’t lose anything by doing it and it may be integral to not losing any personal things.
13) Next it will ask for you internet connection stuff….know it or set it up later.
14) Next it will ask you to create a new local account to administer the computer. IMPORTANT: Do NOT name it the same as the previous account! It will overwrite the previous account completely!!!
15) After creating the account you will automatically be logged in as the new admin!

From here you can access the previous account and change the password to one you will hopefully remember!
Now you can delete the newest account and continue with the old account.
Every once and a while it asks me for a “keychain pass” I just click cancel and continue.

I hope this helps!

Two ways to try to recover a lost password:

One way, although there's no real way to recover a lost root password, you can change the root password even if you do not know the current one. You must have physical access to the machine in order to accomplish this task.

Click Restart at the login window
While the computer is restarting, hold down "Command-S" ( The command-S means the apple key + s) until you see text scrolling through the window.
This boots the computer into single user mode.

At the Localhost% prompt type:
/sbin/mount -uw //sbin/SystemStarter

You will then see various services starting up.

When the Localhost% prompt reappears, type:
passwd root

It will then ask you to type the new root password twice, so do so.

After entering the new password, type:

At the login window, enter username root wih the new password.

Once you are connected, you can use the Multiple Users application (/Applications/Utilities) to change your normal user's password, or create a new user account.\

The 2nd way to recover a lost password is:

to change the administrator (known as "root" in unix) password on a Mac OS X Tiger, Panther, etc., computer. The key to unlocking your system is the Mac OS X install disk.

Once you have an install disk in hand, double click on the Install Mac OS icon and you'll get a window with a big graphic and a restart button. Click on it, and your PowerBook will restart and go straight to the install process.

But don't install the OS again!

Just click through windows far enough until you get the regular set of choices on the menu bar. One of those menus is Utilities and one of the choices on that menu is Reset Password....

Using this tool, you'll be able to change your password to something you know. Then choose Quit from the Installer menu and when your computer restarts, you'll now know the admin password.

Hope this info helps.

I cant not login in too my users i forgot my password

Thank you for contacting Fixya Support, I am glad to assist.

If you are unable to gain access via the password to login to your Mac OS X desktop, you are going to reset your password.

What you will need to do is use the Mac OS X restore (Disk 1) or the Mac OS X installation disk which came with your Macbook Pro.

Now perform this process:

* Insert your install disc
* Reboot your Macbook Pro

* Press the C key on your keyboard and hold until you see the white screen, grey apple, and eventually the spinning gear.

* Release the C key when you see the spinning gear

* When you reach the Mac OS X install environment, click past the language screen.

* From the Installer Menu bar select "Utilities" and then "Reset Password".

* Within the Reset Password utility, select the User Account you need access to.

* Reset the password.

* Quit the Reset Password utility when you have reset and confirmed the new password

* Quit the Installer and restart your Mac..

* At the log in window, enter your username and newly reset password. You should now be able to successfully log in. * I hope this helps.
