Hi everybody,
This is the setup:
New 2011 macmini. Installed and pre-programed with help of a FHD monitor.
This catalyst server is going to be used as showcontrol server. It is configured in Mac ambient network and the catalyst show works very well. After this the monitor is disconnected, and the Mac mini is accessed thru a Macbook Pro with screen sharing. After a reboot, no monitor connected, catalyst crashes on startup, repeatedly. the only way to resolve this is to reconnect the monitor on the MDP-port.

Any ideas?
