Hey everyone, After doing lots of searching, I found that a lot of the guides are specific to certain user's problems. Can someone refer me to a simple guide for general reinstallation? I found one for the macbook air in the guides section -should I just use that? The reason I want to reinstall leopard on my macbook (dec2007) is because it's been really weird and slow lately and I just want to start fresh. I will obviously save all my documents that are impt on an external drive. Do I have to delete everything else on my mb, or will the reinstallation process automatically erase everything? I wanted to stop by the apple store and ask them too, should I just pick up a snow leopard upgrade? Browsing through the forum, I found alot of threads titled "snow leopard bugs", etc. Does this mean I should just hold off if I don't need it. Thanks in advance.
