Hello. This is my first time posting here. I just got a used early 2014 Macbook Air. Bought it home a few hours ago. Was very pleased with it. It performed as it should. But i noticed the remaining battery time showing was a little low. It was showing around 5 hours. So I decided to do a clean install of Yosemite. As I was doing that, I typed in my serial number on the Apple website to check if i have any warranty left and... guess what, it's a Mid-2012 model!!! When I go to the "About this Mac" screen, it says "MacBook Air (13 inch, Early 2014)". How is this even possible? Can this be faked? I am so confused and disappointed right now. I don't know what I should do right now. I just wanted to share this with you guys. Thanks for hearing me out.
