So this morning I rebooted to install 10.8.1 finally, and it goes through the first spinning wheel acts like it's going boot into the desktop almost starts to fade and then it goes back to a spinning wheel that spins and stalls and then spins and stalls, non stop, I tried doing a verbose boot but that just starts booting with tons of things passing by and then goes to a blinking cursor. I can boot in safe mode but nothing in the logs or anything. I am now reinstalling, but out of curiosity anyone else have this happen?
