Snow Leopard has officially been discontinued, but is the only way to start fresh on a CustoMac without access to a Mac. I present another method to obtain the Snow Leopard DVD right through Apple Store online. You will have to do a bit of homework on this as you will be calling Apple Store online and requesting a Snow Leopard disk. What you will need to do is get a Macintosh computer detail of a system that was released with Leopard and then explain that you want to upgrade to Snow Leopard but are unable to find a disk via the store online or any curbside store. Only reason I say to get some older Mac info is encase they ask you for what system because they are going to make sure you can run Snow Leopard on it so make sure you don't choose a PowerPC version Mac. You also want to say that you want to upgrade to the latest version but are unable to because you don't have access to the App Store online. That was introduced in 10.6.8. so with a tad of white lying you should be able to obtain a Snow Leopard disk via Apple. You might even be able to get the Lion USB stick as well. I know Snow Leopard works as I have conformation of this from a close personal friend who I told to call Apple a get a disk after he received a MacBook running Leopard and needed to upgrade to run WoW on it. He called and was able to buy it for $21.62 after shipping. I do not know if this is a fixed price but its a heck of a lot cheaper then $100. that you find on Amazon or eBay.
