Upgraded my hard drive from a 250gb to a 500gb. After reinstalling Mountain Lion, I did a restore from my TM backup. All seemed to go well, and was quick.
The system told me to reboot after the install and again all was good, but it won’t complete the boot. Apple symbol comes up, progress bar starts up, slows down, then stops. I am looking at a screen that is ready to start the GUI, but... it just sits. I tried restarting, no different.
