I bought Macbook Air with 4GB Ram and i want to upgrade to 8 GB RAM is that possible?
Macbook Serial Number is C02GR1SADRQ4
It is not possible to upgrade the memory in a MacBook Air as it is soldered to the motherboard.
Even by Apple Store?
Nope they would have to replace the logic board with a different one that had more ram soldered on, which they will not do.
Your only option is to return or sell the macbook and then buy another one that has more ram built in.
If you had it for more than 14 days, they will take it back.
