Hi Everyone. I took the plunge again and have come back to Macdom. I had a couple of sticks of matched memory for my standard white macbook. I popped out the old ram and put in the new. However, the old memory, the metal contact pins, had a white substance on it. Is this normal? I'm thinking perhaps glue to prevent the memory from moving. Other than that, it can only be corrosion, and that on a 6 day old MacBook isn't good. Anyone got any ideas ? Also, is there such a key as minimise all in OS X Leopard?
