Hello all. I am running "Leopard" on my mac that I have been running since 2009. I have never updated my software and I now realize that is a mistake. I want the newest OSX which happens to be Mountain Lion. I've read that if I get the disk I need either Snow Leopard or Lion to upgrade and I can't download it from the Mac store because I need Lion or higher. So what the heck do I do? Do I really have to purchase a new macbook or what? Thanks in advance for the help.
