Can't install mavericks on a MacPro Early 2008
This machine is listed to be supported. After download, I started installation, Mac rebooted - and - got stuck right after reboot with a dark grey screen. Same happened when I tried to install from a USB boot disk with Mavericks installer on it.
All software is latest version, no special hardware drivers installed. Current system is 10.8.5, running without any problems.
Machine configuration (sorry for German):
