I just received my new retina MacBook Pro purchased online from apple.ca. However my f3 button came with a chip. I've upgraded the specs of this Rmbp 13 so I don't think I can just exchange it at the store. What's my best option here? I kinda don't want them to open open up my laptop which is brand new.
Should I just return this? I don't even know if I can return an upgraded rmbp.
