Since the first ARM systems (may be before) you can’t upgrade things on your own, i had an Air which can be SSD upgraded but not memory upgraded. Memory can only be upgraded from factory.

Unless you are dosdude on Youtube

You could just solder on a new ram set

The amount of people for whom this is a "just" kind of task is very very low. I don't think "just" should be in that sentence ;)
