24" iMac core2duo. Brand new hard drive. I just updated to the most recent version of Snow Leopard. After restarting after the update, I can't login to any of my user accounts. It goes to a blue screen, then back to the user account/login screen. I've tried each account, and can't login to any of them. Any guesses?
Logic Pro, iOS 6.1, Using new MBox and condenser mic
I have tried rebooting with the original OS CD, and holding down the "c" key. Didn't boot up using the CD. I tried rebooting and holding down Shift +c, and that didn't work either. Apple, you're bringin' me down.
