hi I was trying to help my aunt with late 2009 MacBook. She got from ubid website listed as a refurb. Anyway she couldn't make any changes because last admin never cleared password. I did some research and took me into single mode with black and white screen. Had me do some sbin fsck -fy stuff among other things and now no matter what I do I can't get past apple gray screen with logo spinning. I don't have recovery disc. Please help otherwise I may need to buy my aunt a new computer!!! Thank you in advance
