Ok, Thank you so much. Now, because I am not the most technically savvy person, I have a few questions about the process. I am taking college classes and have assignments on my mac that I need, would I need to just save them to a usb and load them back in after the hard drive had been erased? I also have microsoft word, powerpoint, and excel and after erasing the hard drive will all of those apps be erased? It seems as though it would be extremely hard to get those apps in particular back up. I bought the apps online(so i only got the download and not the disk).
I am not worried about any other apps but I am just afraid I won't be able to get those apps(word, powerpoint,etc) working again, or myself not having a clue what to do to retrieve it.
Now also I have never turned time machine on. When I went to buy my macbook pro at the store it was just one of those things that I thought I did not need so I did not look into it. Based on this fact does this mean I can't do the time machine back-up?
Once again thank you so much for all the help, I really appreciate it!
