Okay so I have this MacBook Pro my brother bought me a few weeks back but its been off because the charge died and the charger I had wasnt compatible. Last night when I got the charger I held down Command and S and mounted the drive then used :rm /var/db/.applesetupdone and this was supposed to let me create a new account at start up. Well now I turned on the MacBook and I just get a never ending spin wheel on a grey screen. I also tried pressing Command and R at startup to use time machine but theres no dates to go back to. Also i tried using resetpassword in the terminal but I get a message saying I dont have permission; I do NOT have the dvd/cd with the OS or a good internet connection so I cant use either of those to bring my MacBook back to life. How do i fix this?
