Hi, after an accident with my MacBook and the trackpad and keys melting I sent it off to my insurers, they told me they can't repair it so will replace it for a brand new one. The model they've offered me is me294b/a. I told them that when I bought my MacBook I paid extra to upgrade the RAM to 16gb and keep the ssd at 256gb. I think because it was a custom order they've had to replace it like for like or better and because they can't get the custom orders 2.3/16/256 they've offered me a 2.3/16/512. The model they offered me is a late 2013 if I'm right?? The question I want to ask, apart from the obvious ssd upgrade, are there any other differences between my old 2012 macbook and the new one they'll be sending me?? Thanks for bearing with me, I'm stuck on my mobile and this post may not be edited perfectly!
