can i upgrade the memory ram in a Mabook Air 2014?
Sadly, no Apple soldered the RAM to the logic board. The good news here is sometime in the future you should be able to upgrade the SSD, its replaceable! Presently there are a few vendors looking at making upgrades for this series just not available yet.
short answer no you can’t long answer yes if you go on ebay or a part retailer you can probably get a new logic board and thats what the ram is sottered onto look for that and swap it out with the old one. save the old one though cause with an adapter you can connect that to a monitor or tv and it will run
