I am trying to install software update in macbook, but when it says downloaded completed and you need to restart your machine, I press Restart button but my machine does not restart, it just gets freezes; when I try to restart it from Apple menu it restarts but when I try to restart when software updater asks to restart it, it does not restart and blank screen appears without dock and topbar; just wallpaper appears.
I am new to Mac OS. So please help me to solve this problem and install updates successfully.
