hi everyone!! i'm andy, and i'm new here, so if i did anything wrong please lemme know. i tried to sort my thread into the right forum and i think this is where it's supposed to be. but anyway, this is prolly a really common question, but what exactly does it mean when my macbook begins the whole startup procedure and just hangs at the blue status bar before the login screen for hours? i'm totally not a computer expert, but i'm taking a wild guess... does my hard drive have a problem? and if so, what can i do about it? thanks so much!!
