Ive had my MacBook for a few years now and I have never had any major issues. I left it on running yesterday and today it had obviously run out of charge and died, so i plugged my charger in and turned it on. The Mac turned on fine the went to my desktop, a message came up saying that the dates of my mac are all basically out of whack, which may cause some of my applications to run erratically. Before i could do anything the screen went black as if it had turned off, but the light at the bottom of the actual mac that lights up when the mac is on was still flashing, and i could hear noises as if it was on coming from the computer. I had to turn it off by holding the button down. I have tried turning the mac on a few times now and each time it dosnt even get to the desktop, it turns on like normal with the apple logo, but then switches to a blue screen and goes black again. This keeps repeating. I have tried calling apple support but they dont take calls on Sundays and neither does any apple stores. I really need help as i have alot of important documents on there! thanks.
