My 2009 macbook has 2gb ram and my 2010 macbook pro has 4gb ram. I bought 8gb ram for my 2010 macbook pro and is it possible if I can put the old ram in the pro into the 2009 macbook? Would there be any issues if I do? Thanks!
Thanks.. My 2009 Macbook says DDR3 so I'm guessing it should work like you said.😀 If anybody wants to confirm or add any more info that would be appreciated!
Then please explain why exactly a 2009 macbook running snow leopard, one year older than the other computer i have, will "ignite" if I put in the 4gb ram?
