hey all ive had my black intel macbook since my birthday 1/24/07......and i have a problem thats not all the time but once in a while and its REALLY annoying......for example i would shut down my macbook normally..... and when i would go to turn it on it will load up and show the status bar load.....and when it ask's me for my password i will type it in and when i hit enter it shows a pinwheel and dosent do anything just sits there......ive left ir for 20 mins 1 time and nothing......to the point im hard rebooting over and over again untill it works.....it usually takes me 1 or 2 reboots to work but this time took me over 1 1/2 hours to make it work......i dont kno what it is but also my dad and mom's macbook does this also.....is there a fix to it?......i have all my updates and so do my parents......its really bad when i have work to do and my macbook is asleep and i open it for it to do the same thing even when its not shut down......please help
