Bought Used macbook pro, don't have administrator password and don't have the OS disc. Is there a way I can reset or delete the password?

I recently bought a used macbook pro. I can pretty much do everything I need on it until I want to change setting and such things. Then it asks me for an administrator password which I do not know or have. On top of that I do not have the OS disc either. Is there a way I can SAFELY reset or delete the password so I can set my own without the possibility of screwing thing up. LIke I said I can do most anything. I figured this out when attempting to tether it to my smartphone for internet access (I do all the time from my desktop but my desktop is a PC so things are a little different) I am a very new mac user, I have always been a devoted PC user until now. I have to say I am really loving my macbook pro 🙂 I may just stick with mac from now on (if I can get this problem figured out without too much stress.


I am looking for the safest and best way to fix this issue where nothing I do would mess up the laptop. I can use it now and I do not want that to change, I just want to be able to change my setting and set a password of my own. PLEASE HELP, THANX!

MacBook Pro, Mac OS X (10.4.8), I am not 100% positive on the OS

Hey mate!


As you don't have the disc available, and don't know the password already, you're in a bit of a pickle.


Follow the step by step process of this website, and you will be able to reset the password. Be very cautious and type ONLY what you are told via the steps, as you're using the equvilent of Terminal, you could without too much effort muck up your Mac.


As i said though, I've done this a thousand times, if you follow it word for word, character for character, you'll get your password reset.


Good luck mate,

Regards,

Zet.

Hi


There actually is a slightly easier way in OS X 10.5 or greater.


1. Start up in single-user mode (hold Command-S as the computer starts up).

2. Type: mount -uw /

3. Press Return.

4. Type this:


passwd (user's short name)


Replace "(user's short name)" with the short name of the user account whose password you wish to reset. If you are not sure what the account name is, you can get a list of user names by typing: ls /Users



5. Press Return.

6. Enter a new user password.

7. Press Return.

8. Type: reboot

9. Press Return.
