So I'm basically a newbie and an idiot when it comes to computers.
Here's the problem: I didn't use a log-in screen initially when I started, but felt the need to do so when my brother would always use my computer, so I didn't pick a user name or anything it was just the same as how when I first got my computer I put my first and last name for the user and then I picked a password so when I first restarted my computer the password wasn't working because there was a slight problem with my username which i figured out that i actually double-spaced between my first and last name after many hours so i managed to log in and change my user name and password so when it started I just wanted it to start with the name Jackie. Well unfortunately, last night my macbook rebooted while i was sleeping, dunno why. and so now it's like i never even made any adjustments it's back to my old user name and it won't take my password and it won't take the double space. and i have the startup disk but i dunno what to do because i dont want to reformat my whole computer and when i did use the cd to just reset password i clicked my user name and reset password however when i restarted the computer, nothing had changed and when i tried to go back and went to utility and then reset password no authorized users exist at all!!! what happened? what do i do?? please help.. i'm almost at my wit's end...
