    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?

    Apple have been using some sort of white/grey substance on the RAM contact pins for a while now - looks like corrosion but isn't - possibly acts as a lubricant when pushing them into those tight slots.

    Does not look nice but nothing to worry about !

    It's lithium grease used to make RAM installation at the factory easier.

    As for your "minimize all" question, try Option-Command-M.

    I think its normal. I was watching a video on youtube of a guy switching out memory and he mentioned how the memory already in there had white stuff on it (he made a smart remark about how its probably made by Samsung).

    I doubt its something to worry about.
