Hi, All of a sudden two days ago I began getting the random shutdown problem on my MacBook 2GHz Intel Duo core, which was manufactured in the 19th week of production. This is a brand new problem. I just installed the firmware to correct this, which I wasn't aware of until I went to software update. My question is, is this just a coincidence? Or is it possible that this was some warped way of letting me know that the update was availavble???
