I installed the new beta of OS X last night, and all went smooth until it started to boot up. All it does is go to he apple logo with he spinning circle gets stuck and goes completely black. I've friend resetting pram, smc, I've tried holding option, removing part of the ram, holding option, none of these things work. I also don't have OS password on it. I also don't have another mac so I can't use the FireWire boot
