Hi Everybody! So here is the problem. I left my Macbook Air alone and someone has messed around with it. He or she (most likely he) has changed the Admin Password. Also, you know when you enter cmd + R at the startup and go to Password Reset Utitlity. Well he put some password there too. Because what i was going to do is I was going to reinstall the OSX through recovery partition, but now I can't do that either. I have no access to my laptop at all. I tried contacting Apple through the phone as we don't have Apple store here in Rochester, MN. They gave me a address of the apple certified store in rochester and told me that they could reset it for free. However when I went there they said it was going to cost me 60$. Does anyone know how to fix this? Please, I miss my mac so much and I really cannot afford to spend $60 on this.
