Hello! I have a Macbook Pro and about two weeks ago it was working fine. I went to the park two weeks ago and brought my laptop to work on some files in Microsoft Word. I was there for about two hours total.. I was sitting in a shade, but it was still somewhat humid out. (don't know if this has to deal with it)... Anyhow, later that night I get home and it takes literally like ten minutes to get to the desktop and when I would move the cursor it would take five seconds for it to respond and when I opened up Firefox it would just freeze up and I would be forced to shut it off manually... So the first thing I did was go into safe mode so I could back up all my files. I backed them up through mediafire.com and I never got around to actually trying to fix my laptop til now. When I went into safe mode, the laptop seemed to work fine. Then I would try to go back to the normal mode and it would just go extremely slow so I decided deleting all the content and reinstalling os x would be the best and most simplest way to fix whatever the problem was. So I went into recovery mode from the startup, deleting all the contents from the disk utility, and then afterwards went to reinstall mac os x, but every time I try to install it I get a prompt that says "Mac 10.7 OS X is not available", then I go back to the recovery mode menu. I do have an internet connection so I know that is not the problem. I am confused why I can not install the OS. Also I have a disc of OS 10.6, but when I input into my laptop it just ejects.. It will eject for any disc you input it so I am confused on what to do.. Any help would be very much appreciated. Thanks!
