Upgrading - I thought

Mi Problema

Lack of memory and the word of the Apple salespeople that we could upgrade the memory got us to buy the tool.

Mi Solución

We successfully opened the machine - and successfully closed it again (wohoo!)

Mi Consejo

Yeah! Don't expect to upgrade the RAM of a MacBook Air. Ever. Don't expect to upgrade the SSD either unless you have the unconventional gumstick variant of SSD that Apple uses.
