Background: I bought my macbook pro a few days ago and installed a Vertex SSD. I checked the system for updates and it said I had the EFI update... So, I ran the update and the laptop turned off, turned back on to a white screen, made a buzzish noise, and repeated 3 times. Then the mbp booted up fine and went to check for updates again, that update was still there. 2 questions... 1) Is it normal to go white screen/short buzzish noise when installing updates? 2)Why didn't the update work? I received no failure notification or anything like that.
