I recently installed the v1.0 macbook firmware EFI that fixes a few sleep issues, and it's completely changed the way my macbook works. If I now close the lid it will sleep for a few seconds, but once I leave it alone it either shuts down/crashes and will power up on opening again. Once logged back in, firefox reports itself as having crashed. Now this never happened before firmware updated - but now happens every time. What can I do??
