    Anyone have problems installing the Macbook Pro EFI firmware update? It's version 2.3. I have tried twice to install this. When my MBP goes to restart, the screen just keeps flashing on and off. I am running Lion and my MBP is a 2011 model. Thanks for the info

    I've only heard of people having trouble when they try to update without the computer being plugged in.
