I recently got my macbook fixed by an apple certified dealer. My macbook originally comes with memory of 4 GB 1333 Mhz DDR3. On the repair sheet it says that they replaced my logic board and memory on unit with the following product SDRAM, 2GB, DDR3 SO-DIMM (product code 661-5860). My question therefore is, did I get cheated out by them taking out 4GB of memory and replacing it with 2GB? I just need to make sure before I call them and blame them for doing this. I posted this in the apple support page yesterday and no one has gotten back, I would really appreciate an answer asap so I can fix this problem before the apple dealer says its been too long.
