I am running OS 10.5.8 on a refurbished Macbook Pro. I am not running an OS early enough to be able to use the Mac App Store. Everytime I go under Software Update it says everything is up to date. I would like to put the latest OS on this computer, but must install 10.6 first (apparently)?? My only question is how?

MacBook Pro, Mac OS X (10.5.8)
