New to Mac. How do I change the short name of the Admin. in "account"?

I just got myself a used macbook from a friend of mine. I would usually format it out of the box, but I guess that's not an option. I deleted everything I can think of, but I couldn't change the Admin's short name. Need help on that and any other advice is welcome.

Thanks in advance.

 

Make a new admin account, give it all privileges, log into the new admin account, delete the old admin account.

You add and delete accounts using the + and - buttons below the listing of users in the Accounts panel of the System Preferences.

 

Thanks, it worked Well deserved rep power.

 

How do I change the name of the BT device? It's still reading "John's Bluetooth device".

 

You can also reinstall everything from the install DVDs.

 

I am happy to help, but it's not that I know these things off the top of my head, it's just that it's usually not too hard to figure out things in OS X.

So... I go to my System Preferences > Bluetooth panel, choose the settings pane, and there under the Bluetooth device name, it says "The device name is the same as the Computer Name in Sharing preference."

I then go to System Prefereces > Sharing, and right there at the top you can type in your computer name of choice.

 

Already realised/done that. Wow, this OS X is really user friendly. So are you mzlin, thanks. Things are great so far. I'm still need to download software updates, or do I?.

 

to see if your apple software needs updates, just click the apple in the top left corner and select software update.... it will check for updates.
