Hi, I'm just wondering what is the best way to upgrade to snow leopard. My Mac Book does not accept DVD but I have downloaded a copy of Snow Leopard Build 10A432 and really want to use it, I initially wanted to burn it to DVD and use it to install but forgot that my mac book won't accept it. What I want to know is the cheapest, most efficient and reliable way to get Snow leopard up and running on my macbook. By the way, I plan on buying Snow Leopard once it comes out but just want to test it out now. Thanks for all your help.
