Hey everyone. I had a MacBook a while back and it broke. I managed to salvage the HD and the RAM. Soon, I am going to buy another MacBook (new white plastic, nvidia series) and I was wondering if I could just remove the HD of that machine and put in the old HD from my last MacBook? Would it still work like the last one did, or would there be differences because of new hardware? Not sure about this at the moment. Thanks.
