Hi- Im new to the forums here so i hope im posting this in the right place but i recently bought a MacBook Pro 15" (a month ago) and it was running very smooth with nothing wrong until about 2 days ago. Whenever i try to shutdown my computer the dock and toolbar slide off the screen leaving me with the wallpaper which is normal for about 10 seconds then its supposed to shut off and go black but the wallpaper just stays there and there is that circle thing with spinning gray lines that wont stop. Eventually the screen goes black but the computer is still on... P.S. I repaired my disk and it still happens. Also it shuts down fine on any other user account on this computer. Any help is much appreciated!
