Let me start by saying that I am aware that the ram in a macbook is soldered to the motherboard, is very much not meant to be replaced / upgraded, and the whole laptop can be damaged or destroyed if something goes wrong. I would still like to consider the option anyways because it might be (hopefully is) cheaper than buying a new mac, and it also sounds fun to do.

I would like to try upgrading this mac from 4 GB to 8 GB, but I am having difficulty finding ram chips online. I am looking for 2 GB ram chips to swap the 1 GB chips with (this mac has 4 memory chips).

Does anyone know of a good source for these?

Thank you for your time.
