Hi all, I just purchased a new mac mini with Mountain Lion on it. I use my computer almost exclusively for audio production with Pro Tools and my version of Pro Tools doesn't support ML. My current computer uses Snow Leopard and is very stable and I would like to continue to use that until ML support is added for my version of Pro Tools. My question is, will I be able to go back to ML from SL even though the mac mini didn't come with any physical version of the OS? Do I have a license in the app store or something where I could download ML for free or do I need to do some kind of time machine back up before I install SL?
