Relist: Inaccurate answer.
Expert:  Engineer John C. replied 2 years ago.
The name is XXXXX XXXXX username.

A lot of customers don't have an administrator password, so please try entering your username (usually it is already there) and then leave the password XXXXX

Does it work?

If no luck, we can reset the password. Please let me know.
Customer: replied 2 years ago.
no.
Customer: replied 2 years ago.
How can I set the user name as well?
Expert:  Engineer John C. replied 2 years ago.
The username should be there automatically, you can restart the computer and you will see the username there when you try to update any software.

Or fo to Finder, then go to Applications, then Utilities, then double click Terminal to run it.

You will see a blank or black window with a $ prompt. You username is XXXXX XXXXX before the $ prompt.

It's exactly what I thought it was. Interesting thing is they give me a hint about the password. I know I have that correct. Dogs name.
Expert:  Engineer John C. replied 2 years ago.
Please remember that the password XXXXX XXXXX sensitive, for example "A" is different from "a".

If your dog's name is Alfalfa (just an example), try with alfalfa, Alfalfa, ALFALFA, etc.

Please keep me posted.

Thank you

I've tried it multiple ways. It's not accepting it.
Expert:  Engineer John C. replied 2 years ago.
Then you are not entering the right one. What exact Mac OS X version do you have ? Go to apple icon, then About this Mac. You will see the version number under "Mac OS X"

Thank you.
Customer: replied 2 years ago.
10.5. I just installed Leopard. Although most of it installed. Gave me a failed message due to something with my Epson printer. Not sure if this has anything to do with it. Looks like Leopard is working, I just need to update the software downloads.

  • Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill Bill M. Schenectady, New York
