    Welcome to Apple Support Communities

     

    What are you seeing on your computer display now? If you see a grey screen with a grey progress bar, the firmware is being updated. If not, the update hasn't been installed. If you aren't seeing that grey screen, are you seeing the App Store window or just the update window with a progress bar and your wallpaper?

    Press Alt, Command and Esc keys, choose App Store and quit it. Then, restart your computer and run the update again. If you can't close the App Store, hold the Power button to turn it off

    The installation is frozen, so software won't get damaged. However, it's not good to do this because of the hard drive, but it's the only way to turn off the computer
