I have white Macbook that's about four years old. I few months ago, it wasn't turning on. When I took it to the Apple store, they told me that the logic board is dead. Since I am out of warranty, it would cost $600 replace. I am not sure what to do. I definitely don't want to get it fixed and would rather buy a new one. I'm leaning towards selling the old Macbook for parts or something. Will I even make anything off of it? What should I do?
