I recently updated my Mid-2009 15" Macbook Pro to 10.8.3 from 10.8.2 and have been having huge problems since then. Since the update, my computer will freeze when you wake it from sleep. I will get the spinning beach ball and it will never "un-freeze." I have to do a hard reboot. When I do the hard reboot, I get the Apple logo with the spinning gear at the bottom but then the Apple logo turns into a logo that is a a circle with a line through it like there is no hard drive or OS installed. I am forced to go into recovery console and do a repair disk and repair disk permissions. When doing these steps, Disk Utility finds no errors at all. After rebooting from the recovery console, my computer boots as normal and is able to be used. Problem is, I have to go through the whole cycle again when I wake the computer from sleep again. I've called into Apple support and they say to reinstall the OS but I really don't want to do that. I know everything was working perfectly fine before this update and was trying to see if anyone else is having the same issue. Thanks in advance for the help or any advice that you can give.
