Hi, I recently bought Red Alert 3 for Mac. When I ordered I was assured that I could run the game on Leopard 10.5 but it appears I need 10.5.6, could someone please tell me where I can upgrade this? or do I need to buy a new Mac OS disk? I assumed it would fall under the "Software update" category and I am installing updates as we speak.. maybe I have answered my own question but I'd still like to be a assured. 
Sorry if this is a really stupid question by the way, I am still noob with macs.
