MacMini Update - How do I know
I have a Mini I got from a friend after a long period of only owning Windows computers. I recently updated to Snow Leopard (10.6) and then to Lion (10.7). I was checking the requirements on Mountain Lion (10.8) and it says I can update to this OS if My Mini is "early 2009 or newer".
How do I know if I can update to Mountain Lion?
I've asked my friend but he's not sure when he purchased the Mini originally. Is there somewhere on my computer that I can find this information?
