I got this Mac pro with osx. It's a old bussines computer, so i don't have the log-in password for the user or administrator. I had this instalation CD, and it worked fine when i tried holding "c" down while restarting the computer. But i couldn't fix the problem at the moment so i turned it of again. Now it won't start up as usual with the " choose language menu " so i can't get acces to the computer. I really don't know why it does it, and i'm so lost right now. How do i get acces to the computer now, and reset the computer and password? - im from Denmark, sorry for my bad english, any questions, just ask me. Thank you!
