http://www.bestbuy.com/site/Apple%A...218646127726&skuId=5430505#tab=specifications This is the Mac I bought. I have a few questions? Not sure if I bought a new 2010 model or a 2012 one? so... Where can I find out when my Mac was manufactured? What is the difference between my Mac and the retina display ones Did I overpay or is that a good price? Again I a new to macs and new to computers in general I don't know much. I just wanted a good reliable computer. And I heard Macs were good computers. So far I absolutely love this computer.
