Hi everyone, I bought a new MacBook in December last year running Snow leopard 2.26Ghz 2 GB mem 1067 MHz DDR3. model number A1342. I am interested in adding more RAM to it to increase its speed but I am not sure what specifications the RAM should have or where I should buy it from (a reputable place I can trust). Does anyone have any specifics on what RAM i should get for this Mac model and a good place to buy it from? Thank you very much in advance. Michael.
