I'm having the same problem. The furthest ive got the installer to go is at 2 mins left a screen comes up saying osx cannot be installed and a list of shutdown options. The last line on the installer log at this point says;-
loalhostviewer(1956)folder manager is being asked to create a folder (asav) while running as uid0
Anyone got any ideas?
