Easy peasy macbook squeezy.
The guide is very detailed, sometimes overcareful, but its completely ok because the delicate.
I personally skip some last steps because it wasn't necessary, but I recommend those with less experience to stick the guide.
Good luck to further readers.
Am also trying to replace an early 2014 i5 4GB to i7 8GB and need some answers. Will a 2014 i7 be compatible with a 2014 i5?
