I have the Macbook, its 7 months old. And its in great condition, except today as usual it asked me to install the updates so i said yes. and it was in the process, and in the middle i lost my internet connection, and the installation was bugging. So I held the power button down to turn it off. then i turned it back on, and it was taking a while and then a black screen came on with a bunch of codes with another little window saing to restart or turn off coputer. so i did that a few times. then i decided to wait a few hours and its still not working!!!!!!!!!!!!!! Please any advice, or help would be great.
